For many of my ASP.NET websites I've used reflection to get version information about the loaded assemblies, (I used this for statistics and deployment purposes).
On a few of the websites I've noticed an assembly called JScript Thunk Assembly, but I have no idea where it came from - or what it is used for.
I've had a google around for it, but returned nothing useful.
There's no problem with that assembly being there, was more curious of why and where it came from.
Update: After getting curious about this again, I have found where the "JScript Thunk Assembly" comes from. See this shared-source for .NET 2.0: Microsoft.JScript.Runtime.cs#L111.
I can see that a call to CreateThunkModuleBuilder() is made from the internal ThunkModuleBuilder property, but I am unsure how or why it is call from my own application.
(The mystery continues...)
