I am working in a Web Project in Visual Studio 2008. When I hit F12 (or right-click and select Go To Definition) Visual Studio is consistently going to the Metadata file in
In my case, I had just recently changed
to "true" in my site's .csproj file (to find compile errors in my Razor view files: http://forums.asp.net/t/1909113.aspx?How+to+have+Visual+Studio+2012+returned+compile+errors+on+razor+syntax+error+in+asp+net+web+page+2+ ), and when I then built I was getting errors from my within my site's /obj/Debug/ directory. From any of those files (which were out-of-date), right-clicking and selecting "Go To Definition" would give me the [metadata] version.
So for me, none of the solutions here worked, because I wasn't starting from a file that was actually in my project. Deleted that entire /obj/Debug/ directory, the errors went away, and from any normal file I can correctly use Go To Definition.
