After upgrading Enterprise Vault to V12.1 from 11.0.1. the Enterprise Vault /EnterpriseVault application fails with
Could not load type 'System.ServiceModel.Activation.HttpModule' from assembly 'System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
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.TypeLoadException: Could not load type 'System.ServiceModel.Activation.HttpModule' from assembly 'System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
This is hosted on a fully updated Windows 2012 R2 server.
All pre-req's are in place using pre-installation and checked with the deployment scanner.
This appears to be an IIS 8. error with .Net 3.5 and .Net 4 http activation protocols enabled.
Anyone have any ideas how to fix this for version 12.1 of EV?

There are some MS docs on this.

Thanks,
Those microsoft articles only work for iis 7.
I found this...
https://www.codeproject.com/Articles/613812/Solve-IIS-Error-Could-not-load-type-System-Servi
Removing the ServiceModel Module and the svc-integrated handler mapping corrected the error for all EV sites.
Thanks for the assistance.

Yep, I just found that link and was going to post it here but got side-tracked and see you beat me to it. Seems like one of the many new quirks to come in with the newer IIS. I have found so many strange issues with IIS since V7 and I hardly do anything with it. That's progress for you I guess.
