How do I write an IE 8 Add-On in pure managed C#

Question

I would like to write an add-on for IE 8, but I want to use pure managed C#. Is this possible yet? I know for the longest time we were talking only C++.

Answer 1

Ultimately, the C# will end up calling into IE8's COM functions. There's a framework called Spicie that makes this easier, and some other examples here: http://www.enhanceie.com/ie/dev.asp

Generally, it's a bad idea to write browser extensions in .NET because there's a severe performance impact, and there's the possibility of runtime collisions because only one version of .NET can be loaded into a process currently; if two addons want to use conflicting .NET versions, one will fail.
