+### .NET bindings for the SCIP protocol

+|---|---|
+| Change | Add .NET bindings to `scip-code/scip` |
+| Pull request | [scip-code/scip#475](https://github.com/scip-code/scip/pull/475) |
+| Asked and accepted on | [#468](https://github.com/scip-code/scip/issues/468), 17 August 2026 |
+| Fork it came from | [dbhq-uk/scip](https://github.com/dbhq-uk/scip) |
+| Status | Open |
+
+`bindings/` held go, haskell, java, kotlin, rust and typescript, so every .NET SCIP
+producer or consumer vendors `scip.proto` by hand, vela and `sourcegraph/scip-dotnet`
+included. Package id `Scip`, `netstandard2.0`, generated by a `protoc_builtin: csharp`
+entry beside the existing java and kotlin ones, with a nix check and a NuGet publish job
+because those were the maintainer's two conditions. Verified by round-tripping a real
+60,867-byte `scip-typescript` index: 4 documents, 702 occurrences, byte-identical
+re-encode.
+
+This also unblocks the rest. Criteria 1 and 2 for moving an indexer into `scip-code` both
+depend on bindings existing to depend on.
+
+**One thing needs admin action at their end:** a `NUGET_API_KEY` Actions secret. The `Scip`
+package id is unregistered, so the first release creates it.
