Is there a way in .NET to perform the same technique Photoshop uses for Gradient Mapping (Image - Adjustments - Gradient Map [Gradient Editor])? Any ideas, links, code, etc. would be welcome.
I have a question, which Unicode encoding to use while encoding .NET string into base64? I know strings are UTF-16 encoded on Windows, so is my way of encoding is the right one?

I have a .net 4 application that uses a Com Dll to send SMS messages. I used TlbImp to create the interop assembly and that is what is referenced in the application.
When I try to create an instance of this class, it takes a really long time (2-5 seconds).
I ran performance profile in VS 2010 and the call that takes the longest by far is System.Activator.CreateInstance().
I am looking for tips on how to debug or gotchas with using Com Interop.
I look for a free launcher or bootstrapper that checks whether the .net framework is installed, and starts my app1.exe, or app2.exe if not. Alternatively a louncher that checks for the OS version.
At the last PDC (can't remember which talk it was) they gave us the information that it will be possible to share assemblies between regular .Net 4 and Silverlight 4.
Unfortunately I can't find anything on this. Was this feature dropped? What options/limitations are there?
(There are similar questions on SO but they don't say if they apply to SL3 or 4.)

I was using...
HttpContext.Current.Server.MapPath("~")
