问题
I've built a fairly simple website in using Visual Studio 2012 using .net 4.5 version.
When I uploaded the website to my server I get the following error:
Method not found: 'Void System.Web.UI.ScriptResourceDefinition.set_LoadSuccessExpression(System.String)'.
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.

I am aware of this question/answer: http://forums.asp.net/t/1823969.aspx/1 But I find it wasn't very helpful since it doesn't provide any details about where I would correct the references (I am not sure where/what csproj is).
Also I am aware of the similar question posted here with no answers:
Method not found: 'Void System.Web.UI.ScriptResourceDefinition.set_LoadSuccessExpression(System.String)'
Any tips and suggestions how to fix this issue are appreciated.
Thank you!
回答1:
The LoadSuccessExpression property is a new property in .NET 4.5. Since your host only supports .NET 4, this property does not exist when deployed.
You're getting a missing method exception since a property setter is really just a method behind the scenes.
