• VS Code Version: 1.80.1
• OS Version: Windows_NT x64 10.0.19045

Steps to Reproduce:

1. Install C# dev kit
2. Clone C# extension and start debugging the extension
3. Create a .NET console app (I tried .NET 6 or .NET 7)
4. Open Program.cs and click F5. Select C#:
   

Expected
The debugger gets queried for its configuration variables and start debugging.

Actual
C# extension registers two debug providers, but the second provider, BaseVsDbgConfigurationProvider.resolveDebugConfigurationWithSubstitutedVariables (which implements vscode.DebugConfigurationProvider) is never called.

Remarks

• If you have a launch.json with a profile type specified (only one provider is used), step 5 is called.
• If you start debugging from the project in Solution Explorer window (from C# dev kit extension, so only one provider is used), step 5 is called.

This is the launch request for the repro scenario:

-> (C) {"command":"launch","arguments":{"name":"C#: ConsoleApp47","request":"launch","type":"coreclr","launchConfigurationId":"TargetFramework=;ConsoleApp47"}
