Note - this currently only cares about the installed runtimes. It does not confirm there is an SDK. It will also only install a 7.0 runtime. Is that what you expect?

I think this is the best we have for now until the .NET SDK installation API is avaliable to use.

This is to just workaround the scenario where dotnet exists in the PATH and we can hope there is an SDK.

Do you require a .net 7 SDK or higher? Or can you use a .net 6 SDK? Because if oyu only have a .net 6 SDK installed on the path, this will return a locally installed .net 7 runtime (with no SDK information, you won't be able to see the .net 6 SDK from it)

What Andrew is trying to do is find a version of .NET for the target app. The debugger itself will ignore DOTNET_ROOT and run on its own runtime.

It would be whatever the user's target framework would be.

The scenario is that the user was able to build their application with dotnet build and I was hoping this API would help me grab the dotnet install path to set as DOTNET_ROOT.

E.g. ~/.dotnet

So if the user's app targets .net6 and they only have .net6 SDK installed, this API will not return the path to the dotnet 6 installation. It will return a locally installed .net7 runtime path. Just want to make sure you know what to expect from this API.

See https://github.com/dotnet/vscode-csharp/pull/6567/files#r1364688699

Maybe instead what should happen is getDotnetInfo should return the real CLI path and the set of SDKs that are installed at that path (via dotnet --list-sdks) - and then you use that.

Because DotnetRuntimeExtensionResolver is really focused on making sure the runtime to host the server processes is available.

Be careful with the clipath here - I believe it comes from here - https://github.com/dotnet/vscode-csharp/blob/main/src/shared/utils/getDotnetInfo.ts#L22

which will return 'dotnet.exe' unless you pass in explicit CLI paths to getDotnetInfo - it looks like you pass in the clipaths option, so I think it will only return a real path if that option has a value.

IMHO getDotnetInfo should probably actually return the real dotnet installation exe path in all cases, but I've been afraid of making that change (not sure what else will break 😆 )

Yeah. This normally worked with omnisharp beacuse I think they set the clipaths but this changed when it was all moved to roslyn.

I think you need some more checks here:

  1. If the architecture of the debugger != the architecture of this runtime, we don't want to use it
  2. If there already is a global .NET runtime, we don't want to use it

We might need to re-write getHostExecutableInfo to get the correct architecture. Is it worth it when we will be throwing away this code for the NET SDK installation API?

If there already is a global .NET runtime, we don't want to use it

Whats the best way to check for this? I thought this was covered with process.env.DOTNET_ROOT

I think you just want to ignore it/not compute it if we are trying to get a different architecture. In other words, if you want to target x64, but you are on an ARM64 mac, you need to download the the .NET Runtime yourself

Normally we wouldn't use DOTNET_ROOT if there was a globally installed .NET SDK. I would think you would want to exec dotnet --version and if that succeeded: we use the global version.

dotnetRoot = path.dirname(hostExecutableInfo.path);
} else {
dotnetRoot = '';
}
}
