Hi @vadash! I'm Dosu and I’m helping the Roo-Code team.

Codebase indexing in Roo Code depends on Tree-sitter language support to parse code and identify semantic blocks like functions and classes. C# (dotnet) support may be incomplete or missing in Tree-sitter, which likely explains why no blocks are found in your dotnet project, even though it works with TypeScript projects. This is a known limitation, and the documentation does not list dotnet/C# as a specifically supported language for indexing, so effectiveness may vary or not work at all for C# projects docs.

If you want to dig deeper, check Roo Code’s logs for any errors or warnings during the indexing attempt—they might reveal more about what’s happening. You could also try indexing a minimal C# file or project to see if any blocks are detected, or test with another non-TypeScript language to compare results.

There isn’t any official troubleshooting guidance or workaround for dotnet projects in the docs right now. If you need robust C# support, you may want to keep an eye on future releases or updates to the documentation docs.

To reply, just mention @dosu.

Just FYI: https://github.com/LuotoCompany/cursor-local-indexing
looks like also uses Tree Sitter and it supports charp
also for extensions that are not supported by Tree Sitter they are indexed as text blocks

(Also would be nice if Roo Code codebase index will follow .rooignore if not already implemented)

Thank you for reporting this issue!

Our tree-sitter also supports .cs files so this issue might be related to the C# queries present on src/services/tree-sitter/queries/c-sharp.ts rather than the languageParser.ts file.

Do you still have this issue? I've tested right now and it's working fine, I asked it to create an example project and all the C#/dotnet files were indexed properly.

Closing this for now, but please feel free to re-open if it's still an issue!
