I use VS2012.
I know how to debug the 3rd party code using the .NET Reflector and always used it.
I was wondering whether this is possible with dotPeek from JetBrains or with R# itself without the dotPeek. I am able to navigate to the decompiled 3rd party code, but not step through it.
Any ideas?
I see this question is still driving traffic to my blog, so I'll add an answer: yes, debugging 3rd-party assemblies is now possible with the JetBrains dotPeek decompiler (completely free), by using it as a Symbol server.
In my blog post How to debug anything with Visual Studio and dotPeek, I detail exactly how to set it up and step into 3rd-party code with the debugger.
