[wix-devs] Build and test with Windows on Arm

[Pierrick Bouvier]

Hello Wix developers,

at Linaro, we are working with Microsoft help enable and test projects 
for Windows on Arm (https://www.linaro.org/windows-on-arm/). Wix is 
widely used, and is a project where we are focusing our attention now.

As a first step, I've been trying to build and run tests for Wix4 on 
this platform (using devbuild.cmd).

I successfully installed dependencies:
- dotnet 35 sp1
- dotnet 6 sdk (for all arch)
- VS components for ASP/Dotnet dev
- dotnet core (for x86/x64)

The problem is that some tests are trying to run using dotnet core, and 
on arm64 platform. However, dotnet core 3.1 is not installable for arm64 
(and probably won't be, as it's reaching end of support in December 2022).

Is there a way to deactivate those tests for this platform specifically?

Beyond that, why Wix is supporting all those older Dotnet versions 
(customers need or codebase need)?

Thanks,
Pierrick
