Quick answer

Godot C# builds fail with 'SDK Godot.NET.Sdk could not be found' when the .NET SDK is missing, not on PATH for the shell, or the SDK version does not match the editor.

Most likely fix: Use the .NET editor and install the .NET SDK

How to fix it

Try these in order — the most common fix is first.

  1. 1. Use the .NET editor and install the .NET SDK

    1. Download the .NET version of Godot
    2. Install the .NET SDK version the Godot docs list for your editor
    3. Run dotnet --list-sdks in a terminal to confirm it is found
    Did this fix it?

  2. 2. Match the SDK version in the project

    1. Open your .csproj
    2. Make the Godot.NET.Sdk version equal your editor version
    3. Rebuild with the Build button in the top-right of the editor
    Did this fix it?

  3. 3. Set DOTNET_ROOT for command-line exports

    1. Set DOTNET_ROOT to the .NET install folder in the same shell
    2. Re-run godot --headless --export-release
    3. Pin an SDK in global.json if a newer SDK breaks resolution
    Did this fix it?

  4. 4. Check platform limits

    1. Godot 4 C# projects cannot export to the web
    2. Install .NET export templates, not the standard ones
    Did this fix it?

Symptoms

Build or export fails with 'The SDK Godot.NET.Sdk/4.x specified could not be found' or '.NET Sdk not found', sometimes only from the command line.

Why it happens

  • Using the standard editor instead of the .NET editor build
  • No .NET SDK installed, or DOTNET_ROOT not set in the shell running the export
  • Godot.NET.Sdk version in the .csproj does not match the editor version
  • A newer .NET SDK conflicting with older tooling
