I would like to track down a possible error in Visual Studio, but it is terribly difficult without debugging symbols for Visual Studio itself. Does Microsoft provide these features?
In the updated Visual Studio, it should already be possible to download symbols from Microsoft (Check: Tools-> Options-> Debug-> Symbols). When it comes to debugging Visual Studio itself, take a look at this post.
No, the closest is the debugging symbols for the libraries, which can be downloaded after the steps here . But, as I said, this is not for the visual studio itself.
Based on my experience, most Visual Studio libraries had characters on a character server. msenv.dll is one of the most important.
