Forum Post: RE: Some Problems after UR 12 - MissingMethodException

Hello Gus,

i resolved the problem today :)

I was sure, that the problems cause from an old Microsoft.Xrm.Sdk.dll.

So i found a version, which was not up to date after RU12 installation - In .net GAC:

C:\Windows\Microsoft.NET\assembly\GAC_MSIL\Microsoft.Xrm.Sdk\v4.0_5.0.0.0\Microsoft.Xrm.Sdk.dll

How to resolve the Problem:

1. Stop Asynchronous Processing Service (And helper Service)

2. Save the .dll in the folder

3. Replace it with Microsoft.Xrm.Sdk.dll from C:\<Path to CRM>\Server\bin

4. iisreset

5. Start the services

Now, everything works fine!

Thank you for your help!

Best Regards,

Benjamin
