For reference, in this thread you are working with this library: Shell Extensions (.NET)
When testing it, I could not make that work at all. Not getting any errors, but it produced no preview for me.

Something you may or may not know, it has always been adviced against The Shell and Managed Code
CLR 4 and SxS execution is what allows this to happen using .Net 4, see for example CLR Inside Out: In-Process Side-by-Side
Still there are considerations, for example the Edanmo library used here is a managed library compiled for .Net 2, so it will load and run under the CLR 4 engine along with the registered shell handler. So technically it will be ok to use this with a .Net 4 class library.
