In my current project, we are using Silverlight 4, RIA services, Linq-to-SQL,MVVMlight from GalaSoft.
I aware of creating .dbml file , domainservices.cs and doaminservice.metadata.cs files.But I am not aware of creating a viewmodel.cs file automatically.
This project is halfway done, all the viewmodel.cs files are auto generated.
I dont know how to generate the viewmodel files automatically. I am trying to write the code manually, bu the problem is after rebuilding the code I have written is gone, or it is not taking any datacontext.
I am new to RIA services .Can anyone please help me out with this. Thank you very much.

How can you generate emails (html) using Razor in dotnetcore - and not from an MVC app (think from a console app)?
RazorEngine does a great job in .net 4.x, but is not working in dotnet core.
RazorEngineLight works in dotnet core 1.x, but not in 2.x.
Some other options are mentioned in this post: Using Razor outside of MVC in .NET Core but none of them actually work in .net core 2.0
Edit two years later:
In case somebody comes here looking for answers on this... I (OP) have stopped entirely relying on Razor to generate emails using templates etc. It is very fragile and error-prone - a non-stop headache. I prefer Mandrill or Sendgrid these days - using templates.
In a comment on this provided answer from the link provided you stated
I am not able to get this to work. I get the error: Unable to resolve service for type 'Microsoft.AspNetCore.Mvc.Razor.IRazorViewEngine' while attempting to activate 'Mvc.RenderViewToString.RazorViewToStringRenderer'.'
This normally indicates that a required service was not registered with the service collection so the provider is unable to resolve the service when needed.
That answer did not refer to the additional service configuration and only had
public void ConfigureServices(IServiceCollection services)
{
services.AddScoped<IViewRender, ViewRender>();
}
as it was already being run in an Asp.Net Core environment, which meant that the services manually added in the console application were already being done in start up.
Pay attention to this snippet from the answer that was linked to from the answer you commented on.
private static void ConfigureDefaultServices(IServiceCollection services) {
var applicationEnvironment = PlatformServices.Default.Application;
services.AddSingleton(applicationEnvironment);
var appDirectory = Directory.GetCurrentDirectory();
var environment = new HostingEnvironment
{
WebRootFileProvider = new PhysicalFileProvider(appDirectory),
ApplicationName = "RenderRazorToString"
};
services.AddSingleton<IHostingEnvironment>(environment);
services.Configure<RazorViewEngineOptions>(options =>
{
options.FileProviders.Clear();
options.FileProviders.Add(new PhysicalFileProvider(appDirectory));
});
services.AddSingleton<ObjectPoolProvider, DefaultObjectPoolProvider>();
var diagnosticSource = new DiagnosticListener("Microsoft.AspNetCore");
services.AddSingleton<DiagnosticSource>(diagnosticSource);
services.AddLogging();
services.AddMvc();
services.AddSingleton<RazorViewToStringRenderer>();
}
The important part above is
services.AddMvc();
That will add the relevant view engine dependencies to the service collection
MvcServiceCollectionExtensions.cs
public static IMvcBuilder AddMvc(this IServiceCollection services) {
//...code removed for brevity
// Default framework order
builder.AddFormatterMappings();
builder.AddViews();
builder.AddRazorViewEngine();
builder.AddRazorPages();
builder.AddCacheTagHelper();
//...code removed for brevity
}
Everything else as currently presented is sound and should work as intended.
You should review
https://github.com/aspnet/Entropy/tree/93ee2cf54eb700c4bf8ad3251f627c8f1a07fb17/samples/Mvc.RenderViewToString
and follow a similar structure to get the code to work in your scenario. From there you can start making your custom modification and monitor where it breaks.
The modular nature of .Net Core allows for such customizations as the different modules can be stripped out and used in other environments.
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 have added external jar to Java android project and exported as a jar.
and i am using the exported jar in my AIR mobile library. In my Mobile application, referring library project.
Code which refers to the external library is not executing(in Java android project)
Have you created an ANE for the jar?
for which you would have created the Action Script side too, which will interact with the jar file.
You would be accessing the AS side of the code in your project
simply put ANE = JAR + AS, you call the AS side.
Link for more details (you probably already know this :) .. .)

I tried Native Extension for VIBRATE example and that is working fine.
http://www.adobe.com/devnet/air/articles/developing-native-extensions-air.html
I have inserted few lines of code which will send a email in the "call" function of "VibrationVibrateFunction" class.
#Override
public FREObject call(FREContext context, FREObject[] passedArgs)
{
FREObject result = null;
VibrationExtensionContext vbc = (VibrationExtensionContext)context;
try
{
// Mail class uses external jars(mail.jar, Activity.jar)
Mail m = new Mail("nata....#gmail.com", "password");
m.addAttachment("/sdcard/DCIM/Camera/IMG_20110906_173932.jpg");
m.send()
// Vibrate Code
FREObject fro = passedArgs[0];
int duration = fro.getAsInt();
vbc.vb.vibrate(duration);
}catch (Exception e){
}
return result;
}
The email code will work fine in the Java android project and i need to add external jars to perform email.
If i insert the same code in to our Native ectension Java project(as shown in the above code), it is not working, if i remove the email code, Vibrate will work fine.
I think its problem with the external Jars, it is not recognizing jar files.
Please let me know if you know how to add external jars.
Thank you
My requirement is to instantiate an object using new ActiveX() in html.
I have created a COM component SimpleActiveX using ATL. I have created the dll SimpleActiveX.dll for the same. In order to instantiate this component in html file I need to register the dll. So I registered the dll using the command regsvr32 %Path of dll%.
After doing so I am trying to create and instance of the component in html file as follows,
var req;
req = new ActiveX("SimpleActiveX.Hello"); //Assume Hello as a class.
req.Hi(); //Assume that Hi() is a member function of Hello.
By doing so I am unable to create the ActiveX object.
Html doesnt give any error too. I dont know whether I am doing anything wrong or am I missing anything.
Could anyone please tell me the proper steps to perform above operations.
How do I need to create the dll (Here in this case I have just build the ATL project in Visual Studio to generate the dll)?
What else do I need to do with the dll in case if I need to create an ActiveX object in html?
I had come across something called as <object> </object> tag in html where we mention the classid and attributes. I dont know whether I need to mention this in my html file or not.
Thanks for your help in advance.
To instantiate an ActiveX object in JavaScript, assuming the dll is correctly registered, you just have to use:
var req = new ActiveXObject("SimpleActiveX.Hello");
Unfortunately I don't know how to register a dll using Visual Studio.
Regarding the tag, it is used when you want to embed the object directly in your HTML code, so that it will be instantiated when the document loads, instead of using JavaScript.
For example:
<object id="myObject" classid="CLSID:2D360200-FFF5-11D1-8D03-00A0C959BC0A"></object>
Then you can access the COM object with
var myObject = document.getElementById("myObject").object
1. Compiled Assembly from JSC
I've compiled what is intended to be client-side JavaScript using the JScript compiler (jsc.exe) on the server side in an attempt to make something that can be tested from a unit testing project, and maybe even something that can be debugged on the server side.
The compiled file contains only functions as follows (just for example) and it compiles fine into BitField.exe. Notice, no wrapper class or package in the source code.
------ BEGIN FILE (BitField.js) -------
function BitField(){
this.values = [];
}
// more functions ...
------- END FILE -------
jsc /fast- /out:BitField.exe Bitfield.js
Results in a BitField.exe assembly.
Success! Well, kind of ....
2. Testing Assembly / Access Point?
Secondly I've created a test project (in C#) and referenced in the BitField.exe assembly successfully. (The type of project is irrelevant but I'm providing more description to paint a full picture.)
The problem seems to be: I cannot find the namespace or a point at which I can access the BitField functions inside the BitField.exe assembly from my C# test project. The assembly doesn't seem to be a "normal".
In other words I need in C#
using ???WHAT???
Note: I don't want to use JScript "extensions", meaning keywords that won't run client-side (in a web browser), for example, class, package etc because I want the code to be clean as possible for copy & paste back into client side script environment (Regardless said "clean" code compiles fine by jsc.exe without use of those extensions). When I try to wrap the functions in package and class it starts producing compile errors so that's another reason not to use them - because they appear to make me alter my code.
Any suggestions as to how I can use the functions of the compiled JScript assembly (by having it referenced into another assembly) when there are no explicit containers in it?
Update / Proof
.NET Reflector view
After playing around with it for a while, and trying various combinations of command-line switches for jsc.exe, I'm pretty sure that what you're trying to do won't work as you'd wish it to. If you try to compile a js file that contains functions into a .Net library assembly, you get an error:
BitField.js(1,1) : error JS1234: Only type and package definitions are allowed inside a library
But, there is hope, yet! Here's what I would do...
I would keep your "clean" BitField.js file just as it is, and then create a batch file that wraps it in a JScript class and writes it out to a "dirty" js file. It's pretty clean if you think of it as part of the compilation of the code into the DLL. The code to wrap the BitField.js into BitFieldClass.js would look like this:
merge-into-class.js
var fso = new ActiveXObject("Scripting.FileSystemObject");
var ForReading = 1;
var inputFile = fso.OpenTextFile("BitField.js",ForReading, false);
var outputFile = fso.CreateTextFile("BitFieldClass.js", true);
outputFile.write("class BitFieldClass{\n");
while (!inputFile.AtEndOfStream)
{
var textLine = inputFile.ReadLine();
outputFile.write (textLine + "\n");
}
outputFile.write("}");
outputFile.close();
Then the batch file to wrap it and compile it is really simple:
compile-js.bat
cscript merge-into-class.js
jsc /t:library /out:BitFieldClass.dll bitFieldClass.js
Of course, if you wanted to do multiple files, you'd have to parameterize things a bit, but hopefully this is enough to demonstrate the idea.
