Ever wanted to see what the code of the Microsoft ESB is like ?
Microsoft has some guidance on an ESB build with BizTalk. The guidance is around for quite a while. There is a document describing everything and there is even a Virtual PC with the ESB installed.
I was pretty curious how the code was looking so I used reflector a lot on the Image. This is no longer needed since they have posted the sources on Codeplex. You can find the sources >>here<<
