I recently upgraded to Glass v3 from v2.  I am getting this error across my web farm.  Any insight is appreciated.

Thanks.

Do you have .NET 4.5 installed? There was a couple of breaking changes in .NET 4.5

I do not have .NET Framework installed on my development workstation, or the farm.  I do not get the error in development.

What you could try is removing the WebActivator references and then call

{namespace}.App_Start.GlassMapperSc.Start();

From the Application_Start in the Global.ascx.

[tom.p...@xlgroup.com]

That removes that error, however looks there is still some issue with .NET 4.5 being sought:

Method not found: 'System.Delegate System.Reflection.MethodInfo.CreateDelegate(System.Type)'.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.MissingMethodException: Method not found: 'System.Delegate System.Reflection.MethodInfo.CreateDelegate(System.Type)'.

Source Error:

The source code that generated this unhandled exception can only be shown when compiled in debug mode. To enable this, please follow one of the below steps, then request the URL: 1. Add a "Debug=true" directive at the top of the file that generated the error. Example: <%@ Page Language="C#" Debug="true" %> or: 2) Add the following section to the configuration file of your application: <configuration> <system.web> <compilation debug="true"/> </system.web> </configuration> Note that this second technique will cause all files within a given application to be compiled in debug mode. The first technique will cause only that particular file to be compiled in debug mode. Important: Running applications in debug mode does incur a memory/performance overhead. You should make sure that an application has debugging disabled before deploying into production scenario.
