"Go To Definition" in Visual Studio only brings up the Metadata

1. close your solution.

2. delete hidden <name of the solution>.suo file in folder where your solution's <name of the solution>.sln file exists.

3. open your solution.

4. rebuild your solution.

It happens when you don't add reference as a project but point to a dll or exe using Browse tab in Add Reference dialog. If you add reference using Projects tab you should go directly to the source code when you select Go To Definition.

However, if you install ReSharper, you'll go to source code even if you added your reference to a dll/exe using Browse tab.

Looks like it needs to be setup in Resharper as well. My Visual Studio does not navigate to .NET Framework source code until I enable it in Resharper.

Well, another developer found the answer. The specific project we had an issue with was originally added as a file reference, then removed and added as a Project Reference. Visual Studio however, kept both in the csproj file for the web site, causing the issue. He went in and manually edited the csproj file to remove the file reference to the problem project and all is fixed now
