Debugging dynamically compiled code with Roslyn

Question

I'm using Roslyn to dynamically compile arbitrary *.cs files. I am able to generate the DLLs and PDBs and execute methods within the loaded assemblies via reflection, but when attaching the VS debugger from System.Diagnostics.Debugger.Launch(), I'm getting 'source not available' errors. The 'Modules' windows in VS shows that the symbols have been loaded successfully. The source in question lives in a project under the same solution, but is not compiled until runtime.

Has anyone successfully gotten this working? Thanks!

Answer 1

Ah, so the solution was to have:

CSharpSyntaxTree.ParseText(File.ReadAllText(srcfile), path: srcfile, encoding: System.Text.Encoding.UTF8)

Thanks @hvd!
