Boots doesn't work with DotNet5

[SaqibS]

1. I install DotNet5
2. I install boots
3. I try to run Boots, but get an error about DotNet3.0 not being installed.

While it would be relatively trivial to install DotNet3 on the build server, it seems unnecessary since surely DotNet5 is backwards compatible, and indeed I used DotNet5 to install Boots.

Any tips appreciated.

Output below:

You can invoke the tool using the following command: boots
Tool 'boots' (version '1.0.3.527') was successfully installed.

It was not possible to find any compatible framework version
The framework 'Microsoft.NETCore.App', version '3.0.0' was not found.

• The following frameworks were found:
  5.0.1 at [/Users/runner/hostedtoolcache/dotnet/shared/Microsoft.NETCore.App]

You can resolve the problem by installing the specified framework and/or SDK.

The specified framework can be found at:

• https://aka.ms/dotnet-core-applaunch?framework=Microsoft.NETCore.App&framework_version=3.0.0&arch=x64&rid=osx.10.15-x64

Is this running on Azure DevOps? What agent pool is it?

On Azure DevOps, last I checked macos-latest and windows-latest were both working, but maybe an update to the image broke this?

[SaqibS]

Yes, this is on Azure Dev Ops. We're using the macOS-10.15 image.

Our YAML includes the following two tasks:

    - task: UseDotNet@2
      displayName: 'Use .NET Core SDK $(DotNetCoreVersion)'
      inputs:
        version: '$(DotNetCoreVersion)'

    - bash: 'dotnet tool install --global --ignore-failed-sources boots && boots --stable Mono && boots --stable Xamarin.iOS'
      displayName: 'Install latest stable Mono and Xamarin.iOS'

In the failing version, DotNetCoreVersion is set to 5.x.

Ok in this repo, I removed the UseDotNet task completely and that is why it works, I think.

I think the solution is to compile boots for netcoreapp2.1;netcoreapp3.1;net5.0 and it would work everywhere. I had to do something similar when .NET Core 3.0 came out.

Thanks! I haven't built/tried this, but looking at the commit that should fix it. Let me know when this is published and I'll give it a go.

[jonathanpeppers]

Let me fix the build on AppVeyor; then I'll close this when a new package is available for you to try.

[jonathanpeppers]

Let me know if this build works, thanks!

I used 1.0.3.556 successfully on another repo where only .NET 6 is installed, so I think this will work for you. Let me know, otherwise, thanks.
