Disclaimer: I do realize that this is considered an unsupported experimental feature.

The current nightly build does not seem to include #1613 but at the first glance it does not seem to change the logic.

It seems that if my machine already has a .NET SDK the extension will never download the analysis engine:

https://github.com/Microsoft/vscode-python/blob/f18a5ee52999d0cd0d3dec61f5534c6246e85d87/src/client/activation/analysis.ts#L120-L124

The error is:

No executable found matching command "dotnet-/Users/patrys/.vscode-insiders/extensions/ms-python.python-2018.5.0-alpha/analysis/Microsoft.PythonTools.VsCode.dll"

Which is true as the engine was never downloaded.

I'm not sure how to fix it though, is the nuget package meant to be usable if the .NET runtime is not installed? If not, shouldn't the condition be reversed?

By the way, it was hard to find the actual exception as it seems each linter run clears the contents of the "Python" panel in the "Output" tab and the exception is not logged anywhere else.

    Yes, it is usable without .NET. There are two types of engine binaries

    1. MSIL, depend on .NET Runtime preinstalled.
    2. Full package, platform-specific, does not require .NET runtime.

    The plan is that (1) is packaged with the extension since size is relatively small ~4MB.

    The logic is as follows.

    1. Try to determine if .NET-independent components are installed. See if (!await this.fs.fileExists(mscorlib)) {. mscorlib is packaged with the .NET-independent install.

    2. If mscorlib is missing, try to launch pre-packaged MSIL components - perhaps .NET runtime is preinstalled (say, someone also works with C# extension). createSimpleLanguageClient

    Here you see the error since you probably have .NET runtime BUT pre-packaged MSIL bits are missing (they are not currently included in the public insider builds). You can build them yourself - see contributing guildelines. Or contact me [mikhaila] AT microsoft DOT com

    1. If launch fails, extension tries and downloads the complete package, which is ~26MB.

    I got it compiled and working using this:

    git clone --depth 1 https://github.com/microsoft/ptvs
cd ptvs/Python/Product/VsCode/AnalysisVsc
dotnet build
../../../../BuildOutput/VsCode/raw/
mkdir "/Users/$USER/.vscode/extensions/ms-python.python-2018.4.0/analysis"
cp ../../../../BuildOutput/VsCode/raw/*.{dll,pdb,json} "/Users/$USER/.vscode/extensions/ms-python.python-2018.4.0/analysis"

    but then after a few seconds it seemed doing something, I got:
