VS extension does not install when using azure VS2019 hosted image.

[networkfusion]

Details about Problem

nanoFramework area: https://github.com/nanoframework/nf-tools/blob/master/AzureDevOps/TaskInstallMSBuildComponents/TaskFiles/install-nf-build-components.ps1

VS version: 2019

VS extension version: latest

Target: all

Firmware image version: all

Device capabilities output: N/A

Description

The extenstion fails to deploy to azure pipelines when the image is set to VS2019. This is due to the detection of the VM image not being recognised properly and defaulting to installing the VS2017 extension. This could be solved by setting the parameter VS_VERSION to each repo, but this is tedious and not futureproof.

Detailed repro steps so we can see the same problem

Additional context

Make an effort to fix the bug

After some research, it seems that https://github.com/microsoft/vswhere would be able to fix this issue. Mainly the use of the function discribed in https://github.com/microsoft/vswhere/wiki/Find-VSIXInstaller .

Additionally, it seems that this tool is installed on the hosted build agents by default: microsoft/azure-pipelines-tasks#4441

Hi @networkfusion,
😞 Make sure to include the complete Device Capabilities output. After doing that feel free to reopen the issue.
