Hi,
I'm using a plugin which communicate with another application through legacy asmx web services. But I'm getting the following error messages.
Unhandled Exception: System.TypeLoadException: Could not load type 'System.Runtime.CompilerServices.ExtensionAttribute' from assembly 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

I don't have this problem in QA or my local environment but exists in UAT and Production server. All servers are using .NET Framewrok 4.5.2 for CRM 2013. I don't know if it is a best practises to use web services in plugin or not. I don't get it why the plugin is looking into wrong .NET Framework(I believe it is 4.0) for ExtensionAttribute when its moved to 4.5.2.
Does anyone face the same problem?
thanks
