How do I design a type that loads it's properties from the App.Config file in the same way that SMTPClient class, or a TraceListener would? What standards should I follow when doing this?
Look into the ConfigurationSection class and the ConfigurationElement class
Here is a nice tutorial article
http://msdn.microsoft.com/en-us/library/2tw134k3.aspx
and here is a snipped of the system.net configuration group from the machine.config

I am using VS 2013 for a webform project. But when adding a rdlc report I am getting the below message
"NuGet Package restore failed for project VTS: Unable to find version
'10.0.0.0' of package 'Microsoft.ReportViewer.Common'.."
I tried every possible way to dowload version 10.0.0.0; Unfortunately I failed every time. I have installed reportviewer2010 &reportviewer 2015 runtime.
In .aspx page I added this:
<%# Register Assembly="Microsoft.ReportViewer.WebForms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" Namespace="Microsoft.Reporting.WebForms" TagPrefix="rsweb" %>
and in webconfig file
<!--<assemblies>
<add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>
<add assembly="System.Data.Entity.Design, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>

<add assembly="Microsoft.ReportViewer.WebForms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845DCD8080CC91"/>
</assemblies>-->
Nuget package has no dll with Microsoft.ReportViewer.Common 10.0.0.0; There is only one version available i.e Microsoft.ReportViewer.Common 10.0.40219.1;
Getting this error (in the Application EventLog) when trying to display a particular report:
Exception message: The base class includes the field 'reportViewer', but its type (Microsoft.Reporting.WebForms.ReportViewer) is not compatible with the type of control (Microsoft.Reporting.WebForms.ReportViewer).
We have this in web.config for CRM:
<httpHandlers>
<add path="Reserved.ReportViewerWebControl.axd" verb="*" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" validate="false" />
</httpHandlers>
...
<add assembly="Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
We're seeing an error on some machines, but not others.
This CRM machine has the Microsoft Report Viewer 2010 Redistributable Package installed. As I noted in the title, we have CRM 2011, UR 18.
Is there a different version of Report View that we need to install here?
We were able to resolve this issue. We had to install the Microsoft Report Viewer 2012 Runtime onto the CRM web server, https://www.microsoft.com/en-us/download/details.aspx?id=35747.
Microsoft had modified the PublicKeyToken for v2012 (which is version 11.0.0.0), so the resulting web.config edit also was more than just a version change.
The resulting, correct, CRMWeb web.config (for CRM 2011) is:
<httpHandlers>
<add path="Reserved.ReportViewerWebControl.axd" verb="*" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" validate="false" />

I then checked the references of my website project. There I noticed a lot of different MySQL versions are referenced. I tried to delete all references but version 6.7.4.0, however, I can't even delete the references (see screenshot).
I have these files in my bin folder, both of version 6.7.4.0:
MySql.Data.dll and MySql.Data.Entity.dll
How to fix this error?
try to add this to your web.config:
<system.data>
<DbProviderFactories>
<remove invariant="MySql.Data.MySqlClient" />
<add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" description="Data Provider for MySQL" type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data" />
</DbProviderFactories>
</system.data>
Also, you don't need to reference any dlls from GAC. Just use nuget packages (MySQL.Data, MySQL.Web)
I am working in a modularized asp.net mvc4 project. Some views are located in a Class Library project. I already set the web.config to enable the intelligence in razor views. The #model, #Html.* and others are all working well. But when I try to reference a js file in my view by using the #Scripts.Render(). It says cannot find "Scripts". I checked the web.config file. The System.Web.Optimization is in the // node. I also installed Microsoft.AspNet.Web.Optimization package by Nuget.
I tried to type the code in a .cs file to use the System.Web.Optimization members, it works. But I cannot do same thing in the .cshtml file. Even when I typing #using System.Web.Optimization, it prompt me the Optimization cannot be found.
I am not sure what else I can do to resolve this issue. Any clues are very appreciated.
If you have a Web.config at the root of the class library, confirm it contains the following: <add namespace="System.Web.Optimization"/>
If you do not, trick Visual Studio into thinking that it is a web project and enable Intellisense and resolve your issue by adding a web.config file to the root of your class library project (the one that contains the Razor views) with the following contents (taken from this blog post) :
<configuration>
<configSections>
<sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web.WebPages.Razor, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">

</sectionGroup>
</configSections>
<system.web.webPages.razor>

The above is what worked for me when I faced this issue, but here are more links:

Getting System.Web.Optimization to work in a razor view within a class library
I just made a Linq-to-SQL .dbml file in Visual Studio 2010.
I'm getting the following 2 errors, a total of 60 times in total, mostly the first.
The type or namespace name 'Linq'
does not exist in the namespace 'System.Data'
The type or namespace
name 'EntitySet' could not be found
I've found various similar questions here and on other sites, all of which seem to say that some extra assembly needs to be added.
I've added every one suggested, the problem persists. Another odd thing is that VS2010 itself doesn't underline the errors in the editor screen, but it does show them in the error log.
Anyways, I've seen all the existing topics and applied their solutions, the problem persists.
Some technical details:
I'm running Windows 7 32-bit.
I still have Visual Studio 2008 SP1
installed. I just installed VS2010
when it came out and didn't remove
the older one.
I'm running MSSQL server 2008 R2.
And here's the assemblies listed in my web.config file:
<add assembly="System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>

I found this link which solved it for me. The net is that the following must be added to web.config:
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0">
<assemblies>
<add assembly="System.Data.Linq, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>
</assemblies>
</compilation>
</system.web>
</configuration>
Note that the configuration/system.web/compilation tags are already there, and the assemblies/add assembly tags need to be added. This even though System.Data.Linq is readily found by VS when building.
The failure was in App_Code.LinqToObservations.designer.cs, code that's generated by Linq from my LinqToObservations.dbml file.
(Additional background: I likely got into this situation because I enabled Linq after the fact using the procedure found here.)
I've been having the same problem on exactly the same config except for my Windows 7 is 64-bit. Got it solved by doing [project name] -> References -> Add reference -> System.Data.Linq Why do you add references by hand?
Important, you must set in webconfig
<system.web>
<compilation debug="true" targetFramework="4.0"/>
</system.web>
You can try following:
Add reference to System.Data.Linq (Right click on References folder | Select Add Reference | Select .Net tab(Is default selected) | select System.Data.Linq reference | click OK.
I hope this will help you or someone else.
