[BUG] Cannot debug using Debug > Start New Instance in the Solution Explorer

[AnhQuanTrl]

Describe the Issue

I'm currently using VSCode with WSL2. I could debug the application using the traditional launch.json way. However, when trying to debug using the new option in the Solution Explorer, it failed with the following error:

App: /home/arthur/dev/cas/src/ServiceHost/bin/Debug/net6.0/ServiceHost
Architecture: x64
App host version: 6.0.22
.NET location: Not found

The target process exited without raising a CoreCLR started event. Ensure that the target process is configured to use .NET Core. This may be expected if the target process did not run on .NET Core.
The program '[15503] ServiceHost' has exited with code 131 (0x83).

I have already installed dotnet sdk 6.0 and dotnet runtime using the version from Microsoft Feed (Ubuntu). Everything else worked fine except for this debugging feature.
Here is my dotnet --info result:

Weirdly enough, if I'm installing dotnet sdk 7.0, there is a new error as C# Dev Kit tried to use the preinstall runtime instead:

Starting Spawn .NET server...

Starting Clear environment...

I have to uninstall the dotnet-sdk-7.0 so that I can make the extension somewhat work again (except for the debugging feature of course).

Steps To Reproduce

1. Running VSCode in WSL2
2. Installing dotnet-sdk-6.0 through Microsoft feed (Ubuntu apt)
3. Install the extension
4. Try to use Debug > Start New Instance -> it fail even though launch.json work.

Expected Behavior

It should debug successfully using the new debug feature.

Environment Information

• OS: Window WSL 2 Ubuntu 22.04
• VSCode Version: 1.82.8
• Extension version: 0.4.10
