After watching the torturous train wreck of .NET reflector come to its cruel end (i.e. a tool I have to actually pay for, ugh), I am really delighted by the introduction of version one of ILSpy. The options are kind of straight forward you can view your decompiled code in either straight IL or C# (VB to supported in a future release).
You do have a basic search option that can be filtered by Type or Member, however, there remains no options for integrating plugins but this is version 1, and I am sure that will be in some future road map. Watched this video I know you will recognize and appreciate the effort poured into this project. Developers everywhere please show your support visit the home page and download the tools!
