Does SourceLink work with local non-indexed pdb files?

Context

I prototype a feature in VFPT that uses pdb files to go to a symbol in C# project. It would be a compelling case for using SourceLink because that part isn't supported by FSharp.Compiler.Service.

I have had all the bits wired up correctly. You can see the prototype at https://github.com/dungpa/PowerTools/tree/go-to-csharp-project.

Results

To my surprise, SourceLink returns garbled results when reading local non-indexed pdb files of C# projects. I also make a test using your console program, no difference. You can see the test at https://gist.github.com/dungpa/7504c7633a613ba59d04. Most of the time, SourceLink points to wrong locations. Sometimes, it even points to wrong files.

Questions

Should SourceLink support local non-indexed pdb files? Or did I miss something to get this working?

The original design of SourceLink.SymbolStore was to support source indexed pdb files. Supporting pdb files that are not indexed sounds reasonable.

Do you plan to support this use case soon?

It is a common use case since most of C# projects in a mixed C#/F# solution has pdb files for use. This would be a great showcase for SourceLink in the area of design-time tooling.

@ctaggart Have you seen this https://twitter.com/ploeh/status/614328824969490432? People start to notice SourceLink :-)

The Portable PDB format solves these issues. See details in #93. I think the the Microsoft teams will start shipping them and everyone will probably follow suit.
