CC.NET Dashboard Error: Could not load type 'System.Security.Authentication.ExtendedProtection.ChannelBinding'

Question

Late last week I upgraded CC.NET locally and on the build server. The build server is still fine, but locally I am now getting the following error:

Exception Details: Exortech.NetReflector.NetReflectorTypeLoadException: Unable to load types from assembly System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089: Failed to load 1 of the 3612 types defined in the assembly. Exceptions: - Unable to load type: System.Security.Authentication.ExtendedProtection.ChannelBinding Exception: System.TypeLoadException: Could not load type 'System.Security.Authentication.ExtendedProtection.ChannelBinding' from assembly 'System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

I'm afraid this started after a batch of Windows updates this morning. I had another two updates that won't run, 979909 and 982168 (I had an update that wouldn't run last month).

Anyone else having any issues? Thanks!

Edit: I can connect through CCTray and CCNET is running properly. I just can't get to the Dashboard.

EDIT. Thanks to both of you. I uninstalled everything you both suggested and turned off Windows Update per our IT dept. It didn't work yesterday after a reboot, but after a night of rest and another reboot, it seems to be working now.

Answer 1

I got the same exception this morning, seemingly out of nowhere.

Turns out some Windows updates were installed over the weekend. After uninstalling the KB976765 and KB979909 updates, the problem went away.

I hope this helps

Answer 2

There is a problem with the update KB976769v2. It can be fixed as detailed in this KB article.
