I have updated my project yesterday with IdentityModel 2.6, and I can't find why it does not compile anymore with this error.
error ASPRUNTIME : The pre-application start initialization method Start on type
Thinktecture.IdentityModel.Web.Configuration.AppStart threw an exception with the
following error message: Value cannot be null.
I have just updated the package, no code change.
EDIT: The problem comes from missing web.config section described here http://brockallen.com/2013/05/28/configuration-for-wif-session-helper-apis-in-thinktecture-identitymodel/
This seems mandatory and all attributes must be filled otherwise it throws... sessionTokenCacheType for exemple must be filled...
It would be great to have more information on this.
TIA
That's a bug in 2.6. Please upgrade to 2.6.1
