Microsoft.CRM.Webservices.dll is required in GAC for all ISV Web Application
Posted Wednesday, March 17th, 2010
Most applications that I have put in the ISV folder of the CRM website has used the WebService SDK and if you don’t have the Microsoft.CRM.Webservices.dll in the GAC(C:\Windows\Assembly folder) you will get an invalid token error. The other day I build a web application that did not use the CRM SDK but displayed data from an ERP system related to the account. When I deployed the application to the CRM server I still got the same error. I put the Microsoft.CRM.Webservices.dll in the GAC, reset IIS and everything worked fine. So for now on before I deploy an application to ISV folder I always check to make sure the following dlls are in the GAC:
1. Microsoft.CRM.Webservices.dll
2. Microsoft.CRM.Sdk.dll
3. Microsoft.CRM.SdkTypeProxy.dll
Remember you must do an IISREST or stop and start the services.
