I’ve been working on how to recycle the current application pool for my ASP .NET application.

There are 3 steps for doing this:

1. Verify if application is running on IIS that supports application pools (if not, there’s nothing to recycle).
2. Get application pool name (obtained from the DirectoryServices entry corresponding to our virtual directory).
3. Invoke Recycle method in the DirectoryServices entry corresponding to the application pool.

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'.
