I’m working on an architecture project now, and I needed to create an HttpModule which would measure the request time for pages.

So I needed to save information (the time and some other data) in the Begin_Request event and then read it in the End_Request event. I could have used Request.Context, but part of the idea of the project is this information in the current thread because it can be used both in Winforms and in Webforms.
This information is saved in the current thread using a class that implements ILogicalThreadAffinative. When I saved my information in the current thread (using CallContext.SetData()), suddenly an exception (not debuggeable) came up, which said:

System.Runtime.Serialization.SerializationException: Type is not resolved for member 'xxx'.
