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?
Debugging and symbols server are implemented in dotPeek since 1.2 version. This version is in Early Access now.
More info you can find here
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.
Unfortunately, not yet. But this is in JetBrains' near plans.
Yes. dotPeek was released. See this post that explains how to do it in details.
