I'm using enterprise library for logging. So, to hold my configurations, I'm using the client's app.config. The requirement changed to "split EL configuration and UI configuration". I did it using enterpriseLibrary.ConfigurationSource. Split the configurations to app.config(For UI) and EL.config(For EL).
Now I want to hide the reference to this EL.config from app.cpnfig, so that the mere existence of this EL>config is hidden from the User.
App.config Code:
<enterpriseLibrary.ConfigurationSource selectedSource="EntLib Configuration Source">
<sources>
<add name="EntLib Configuration Source" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.FileConfigurationSource, Microsoft.Practices.EnterpriseLibrary.Common, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
filePath="C:\My.CommonServices.Logging\My.CommonServices.Logging\EL.config" />
</sources>
You can use FileConfigurationSource to programmatically load an external configuration file.
During application load or initialization you can load your external configuration file:
FileConfigurationSource fcs =
new FileConfigurationSource(
#"C:\My.CommonServices.Logging\My.CommonServices.Logging\EL.config"
);
var builder = new ConfigurationSourceBuilder();
builder.UpdateConfigurationWithReplace(fcs);
EnterpriseLibraryContainer.Current =
EnterpriseLibraryContainer.CreateDefaultContainer(fcs);
Once that is done you can access your favorite features:
LogWriter logWriter = EnterpriseLibraryContainer.Current.GetInstance<LogWriter>();
logWriter.Write("Test");
The only "trick" is ensuring that the configuration file is always present where you expect (either absolute or relative).

I have tried to create the Razor Class Library with Asp.Net Core in following project structure:
I have used in my web application these settings for localization in Startup class:
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1)
.AddViewLocalization(
LanguageViewLocationExpanderFormat.Suffix,
opts => { opts.ResourcesPath = "Resources"; })
.AddDataAnnotationsLocalization();
services.Configure<RequestLocalizationOptions>(
opts =>
{
var supportedCultures = new[]
{
new CultureInfo("en-US"),
new CultureInfo("en")
};
opts.DefaultRequestCulture = new RequestCulture("en");
opts.SupportedCultures = supportedCultures;
opts.SupportedUICultures = supportedCultures;
});
....
var options = app.ApplicationServices.GetService<IOptions<RequestLocalizationOptions>>();
app.UseRequestLocalization(options.Value);
In Index.cshtml:
#using Microsoft.AspNetCore.Mvc.Localization
#inject IViewLocalizer Localizer
<h1>#Localizer["Title"]</h1>
Unfortunately, the result is only string "Title". I can't load these resx files from Razor Class Library.
How can I use the localization in Razor Class Library like above?
UPDATE: This is very similiar use case - https://github.com/aspnet/Localization/issues/328 - that provides some example.
I haven't tried the accepted answer and based on the comments, it seems the OP didn't get it to work. I implemented a pattern similar to the View/Page locator pattern that MVC/Razor Pages uses namely, that resources can be provided in a RCL or separate assembly and use ViewLocalizer and it'll just find the matching resource string from the highest precedence resource. You can read my implementation and see if it might work for you.

You appear to have forgotten to configure localization correctly using AddLocalization
Using details provided from documentation
Reference Globalization and localization in ASP.NET Core
Configure localization
Localization is configured in the ConfigureServices method:
services.AddLocalization(options => options.ResourcesPath = "Resources"); //<<< This is required
services
.AddMvc()
.SetCompatibilityVersion(CompatibilityVersion.Version_2_1)
.AddViewLocalization(LanguageViewLocationExpanderFormat.Suffix)
.AddDataAnnotationsLocalization();
AddLocalization Adds the localization services to the services container. The code above also sets the resources path to "Resources".
AddViewLocalization Adds support for localized view files.
AddDataAnnotationsLocalization Adds support for localized DataAnnotations validation messages through IStringLocalizer abstractions.
Localization middleware
The current culture on a request is set in the localization Middleware. The localization middleware is enabled in the Configure method. The localization middleware must be configured before any middleware which might check the request culture (for example, app.UseMvcWithDefaultRoute()).
var supportedCultures = new[] {
new CultureInfo("en-US"),
new CultureInfo("en")
};
app.UseRequestLocalization(new RequestLocalizationOptions{
DefaultRequestCulture = new RequestCulture("en"),
// Formatting numbers, dates, etc.
SupportedCultures = supportedCultures,
// UI strings that we have localized.
SupportedUICultures = supportedCultures;
});
//...other middleware
app.UseMvcWithDefaultRoute();
The path to the resource file shown in the example image follows the path naming convention given that
you are using the ResourcesPath option which was set to "Resources". This should allow the view to find the resource file in the relative path to the "Resources" folder.
An alternative is to not use the ResourcesPath option, and place the .resx file in the same folder as the view, following the naming convention of course.
Base on additional details provided it was indicated that the UI project would be packaged as a nuget package.
Then have the resources files packaged into the nuget package and have them unpacked to the resources folder of the target project when when installed.
The resources need to be in the site root to be available to the view, so you then need to reference all the files in your .nuspec:
<?xml version="1.0"?>
<package>
<metadata>...
</metadata>
<files>
<!-- Add all resource files -->
<file src="Resources\**\*.resx" target="content\Resources" />
</files>
</package>

My Spring.NET configuration is using the following type syntax and is working ok.
<object id="JohnUsingVariableSource"
type="XmlConfig.StringInjection.Person, XmlConfig">
<property name="Name" value="${JohnsFullName}" />
</object>
Values for the ${JohnsFullName} placeholder are configured in the app.config file. My requirements have changed and I know need to get the name from the database at startup. How is it possible to overwrite the value in the app.config file ? Can I do it in code without opening the app.config (as here App.Config change value), does spring.NET have a way of doing this ?
Yes, you can do that without modifying the app.config file. Simply implement a custom IVariableSource:
public interface IVariableSource
{
string ResolveVariable(string name);
}
In the ResolveVariable method you read from the db.
The first variable source configured in your config will be the one used by the spring config, if I recall correctly.
From Miguel de Icaza:
We use a library profile that is better suited for mobile devices, so we removed features that are not necessary (like the entire System.Configuration stack, just like Silverlight does).
After years of .NET development, I'm accustomed to storing configuration settings in web.config and app.config files.
When using Mono for Android, where should I put my configuration settings?
If it matters, I'd like to store different configuration settings for different build configurations as well.
I would probably recommend using shared preferences and compilation symbols to manage different configurations. Below is an example of how you can use a preferences file to add or change keys based on the compilation symbols. Additionally, you could create a separate preferences file that is only available for a particular configuration. Because these keys are not available on all configurations, make sure to always perform checks for them before using.
var prefs = this.GetSharedPreferences("Config File Name", FileCreationMode.Private);
var editor = prefs.Edit();
#if MonoRelease
editor.PutString("MyKey", "My Release Value");
editor.PutString("ReleaseKey", "My Release Value");
#else
editor.PutString("MyKey", "My Debug Value");
editor.PutString("DebugKey", "My Debug Value");
#endif
editor.PutString("CommonKey", "Common Value");
editor.Commit();
We have had exactly the same problem in our current project.
My first impulse was to put the configuration in a sqlite key-value table but then my internal customer reminded me the main reason for a configuration file - it should support simple editing.
So instead we created an XML file and put it there:
string documentsPath = Environment.GetFolderPath(Environment.SpecialFolder.Personal);
And access it using these properties:
public string this[string key]
{
get
{
var document = XDocument.Load(ConfigurationFilePath);
var values = from n in document.Root.Elements()
where n.Name == key
select n.Value;
if(values.Any())
{
return values.First();
}
return null;
}
set
{
var document = XDocument.Load(ConfigurationFilePath);
var values = from n in document.Root.Elements()
where n.Name == key
select n;
if(values.Any())
{
values.First().Value = value;
}
else
{
document.Root.Add(new XElement(key, value));
}
document.Save(ConfigurationFilePath);
}
}
}
via a singleton class we call Configuration so for .NET developers it is very similar to using the app.config files. Might not be the most efficient solution but it gets the job done.
there's a Xamarin centric AppSetting reader: https://www.nuget.org/packages/PCLAppConfig
pretty useful for continuous delivery (so a deployment server such as octopus allows to alter your config file for each environment with values stored on the cd server)
there's a Xamarin centric AppSetting reader available at https://www.nuget.org/packages/PCLAppConfig
it is pretty useful for continuous delivery;
use as per below:
1) Add the nuget package reference to your pcl and platforms projects.
2) Add a app.config file on your PCL project, then as a linked file on all your platform projects. For android, make sure to set the build action to 'AndroidAsset', for UWP set the build action to 'Content'. Add you settings keys/values: <add key="config.text" value="hello from app.settings!" />
3) Initialize the ConfigurationManager.AppSettings on each of your platform project, just after the 'Xamarin.Forms.Forms.Init' statement, that's on AppDelegate in iOS, MainActivity.cs in Android, App in UWP/Windows 8.1/WP 8.1:
ConfigurationManager.Initialise(PCLAppConfig.FileSystemStream.PortableStream.Current);
3) Read your settings : ConfigurationManager.AppSettings["config.text"];
ITNOA
Maybe PCLAppConfig is help you to create and read from app.config in Xamarin.Forms PCL Project or other Xamarin projects.
For different configuration in different build mode such as release and debug you can use Configuration Transform on app.config.
I don't see how Windows Azure lets you vary the configuration of an application when you have no choice but to hold configuration settings in web.config (or app.config).
For example...
Quite often projects will make use of a 3rd party library that makes heavy use of web.config. The use of web.config may involve connection strings, app settings or custom configuration sections. A good example of this is ELMAH. A web.config file for ELMAH might look like the following:
<configuration>
<configSections>
<sectionGroup name="elmah">
<section name="security" requirePermission="false" type="Elmah.SecuritySectionHandler, Elmah" />
<section name="errorLog" requirePermission="false" type="Elmah.ErrorLogSectionHandler, Elmah" />
</sectionGroup>
</configSections>
<connectionStrings>
<add
name="MyElmahDatabase"
providerName="System.Data.SqlClient"
connectionString="Server=tcp:myServer.database.windows.net,1433;Database=myDB;User ID=user#myServer;Password=password;Trusted_Connection=False;Encrypt=True;Connection Timeout=30" />
</connectionStrings>
<elmah>
<security allowRemoteAccess="1" />
<errorLog type="Elmah.SqlErrorLog, Elmah" connectionStringName="MyElmahDatabase" />
</elmah>
</configuration>
There are a couple of problems here:
There is no way for me to update or vary whether remote access is enabled between Service Configurations.
There is no way for me to update or vary the ELMAH connection string between Service Configurations.
This is because the web.config is packaged as is into the .cspkg file and ELMAH will not look at the Service Configuration settings (which are the only way I can vary configuration settings between Service Configurations).
I can think of many other examples where this is a problem...
Any data access frameworks that look directly at the connection strings section.
Any custom configuration settings I need to create.
...to name just two.
Am I missing something or is this a significant gap in the configuration management offered by Windows Azure?
EDIT
From the answer and comments below, it looks like this is something that is not well supported. I think that managing multiple solution build configurations to support different configuration profiles is a very weak solution. I should not have to rebuild the solution for each configuration profile I need (there will likely be quite a few). Compilation is not equal to configuration.
I was wondering if there was a way to modify the .cspkg file as it is just a zip file. According to this documentation you can on Linux.
I've looked at the manifest in the .cspkg file and it looks like this:
<PackageManifest version="2">
<Encryption keytype="1" />
<Contents hashtype="1">
<Item name="MyApp.Web.UI_<GUID>.cssx" hash="AED69299C5F89E060876BC16BD3D6DE5130F6E62FFD2B752BAF293435339B7E2" uri="/MyApp.Web.UI_<GUID>.cssx" />
<Item name="MyApp.Web.Services_<GUID>.cssx" hash="7AC81AFF642E4345173C8470C32A41118A4E3CFD4185B82D0ADA44B71057192D" uri="/MyApp.Web.Services_<GUID>.cssx" />
<Item name="SMPackage_<GUID>.csmx" hash="B5E6B83B62AF64C7C11CAC1A394ABBF15D7DB7667A773C5284CE5BE95C5834E9" uri="/SMPackage_<GUID>.csmx" />

<Item name="NamedStreamPackage_<GUID>.csnsx" hash="FA2B5829FF5D9B2D69DCDDB0E5BDEE6B8B0BC09FFBF37DAEEE41CF3F3F4D0132" uri="/NamedStreamPackage_<GUID>.csnsx" />
</Contents>
<NamedStreams>
<Stream name="RequiredFeatures/MyApp.Web.Services/1.0" />

<Stream name="SupportData/MyApp.Web.Services/1.0" />
<Stream name="SupportData/MyApp.Web.UI/1.0" />
</NamedStreams>
</PackageManifest>
Unfortunately, if I re-compute the hash of the unchanged "MyApp.Web.UI_.cssx" file, my hash is different from the one in the manifest.
Hash from manifest: AED69299C5F89E060876BC16BD3D6DE5130F6E62FFD2B752BAF293435339B7E2
My calculated hash: E3B0C44298FC1C149AFBF4C8996FB92427AE41E4649B934CA495991B7852B855
Note that I have not yet changed the file, so the hash should be the same.
This suggests I'm calculating it wrong. My method was as follows:
class Program
{
static void Main(string[] args)
{
using (FileStream fs = new FileStream(args[0], FileMode.Open))
{
ComputeHash(new SHA256Managed(), fs);
}
}
private static void ComputeHash(HashAlgorithm hashAlgorithm, Stream stream)
{
byte[] hash = hashAlgorithm.ComputeHash(stream);
string hashString = BitConverter.ToString(hash);
Console.WriteLine(hashString.Replace("-", string.Empty));
Console.WriteLine();
}
}
The documentation link above, suggests it is straightforward to re-calculate the hash (on Linux anyway).
Does anyone know how to re-compute the hashes?
Passing a Stream to ComputeHash() ends up with a different hash as compared to using the byte[] overload. I don't know why.
Try something like:
private static void ComputeHash(HashAlgorithm hashAlgorithm, Stream stream)
{
BinaryReader reader = new BinaryReader(stream)
byte[] hash = hashAlgorithm.ComputeHash( reader.ReadBytes( (int)stream.Length ) );
string hashString = BitConverter.ToString(hash);
Console.WriteLine(hashString.Replace("-", string.Empty));
Console.WriteLine();
}
This will give you the hash you're after.
As you've probably already discovered, on linux you can get the digest with
openssl dgst -sha256 /path/to/file
I you have items in your web.config that you want to change depending on how it's being built, there is a solution that is outside of Azure that you can use. You can use Web.config transforms. These transforms are tied to your build configuration not your service configuration, but your service configurations a likely closely tied to your build configurations anyway (...Local.csfg -> Debug, ...Cloud.csfg -> Release). If the default build configurations don't work for you, just create the ones you need.
If you want to use different service definitions per service configuration, then it's not supported by the UI, but you can mess around with the build process to make it work
I know how to send mails using the Microsoft Enterprise Library 2.0 using a text formatter. But these emails are always in plain text. Is there any way with entlib 2.0 to send these mails in HTML format?
Well that is funny, I am now writing my own answer.
What I did was use the source code of entlib.
Within
Microsoft.Practices.EnterpriseLibrary.Logging and
Microsoft.Practices.EnterpriseLibrary.Logging.TraceListenerData
I found the classes that I needed.
Copy EmailMessage.cs to EmailMessageHTML.cs
Copy EmailTraceListener.cs to EmailHTMLTraceListener.cs
Copy EmailTraceListenerData.cs to EmailHTMLTraceListenerData.cs
Put these classes in your own new Library Project.
Within EmailMessageHTML change all constructors to match the new classname and than ADD following line to the method:
protected MailMessage CreateMailMessage()
{
.....
message.IsBodyHtml = true;
.....
return message;
}
After that, I had to use this new EmailMessageHTML class in EmailHTMLTraceListener (change EmailMessage to EmailMessageHTML) and also use this EmailHTMLTraceListener in the new EmailHTMLTraceListenerData.cs file.
Compile this new project and than use this in your config as follows (example)
<loggingConfiguration
name="Logging Application Block"
tracingEnabled="true"
defaultCategory=""
logWarningsWhenNoCategoriesMatch="true">
<listeners>
<add toAddress="your#emailgoes.here"
fromAddress="yourserveraddress#goes.here"
subjectLineStarter=""
subjectLineEnder="My HTMLemailLogger"
smtpServer="localhost" smtpPort="25"
formatter="Text Formatter"
listenerDataType="MYLibrary.HTMLEmailLogger.EmailHTMLTraceListenerData,
MYLibrary.HTMLEmailLogger, Version=2.0.0.0,
Culture=neutral,
PublicKeyToken=null"
traceOutputOptions="None"
type="MYLibrary.HTMLEmailLogger.EmailHTMLTraceListener,
MYLibrary.HTMLEmailLogger,
Version=2.0.0.0,
Culture=neutral,
PublicKeyToken=null"
name="EmailHTML TraceListener"/>
</listeners>
</loggingConfiguration>
and add a valid category to log this to of course:
<add switchValue="All" name="OutOfBalanceBooking">
<listeners>
<add name="Database Trace Listener"/>
<add name="EmailHTML TraceListener"/>
</listeners>
</add>
Of course you need some HTML document to than log with EntLib. I leave that as an exercise for the reader.
And indeed! I get a nice HTML email now for every outofbalance booking that customers make on the site...
