PR #640 causes very annoying .NET SDK not found

[ITaluone]

Usage Information

Fallout as developer (not consumer) via Rider

Description

The PR #640 causes a very annoying "bug". It does resist to load the solution if 10.0.302 SDK isn't installed.

Running .\build.ps1 installs it into .fallout/temp/dontet-{win,unix}, but this does not help Rider. Of course you could change in the Rider settings the SDK search path, but you have to do this every SDK update.

Reproduction Steps

• Having .NET SDK 10.0.400 installed and no 10.0.3xx
• Checkout develop

Expected Behavior

Solution loads in Rider/VS

Actual Behavior

Does not load

Regression?

You could argue: yes (because rollForward: latestMinor got this)

Known Workarounds

• Changing rollForward back to "latestMinor"
• Update global.json to this content:

{
  "sdk": {
    "version": "10.0.302",
    "rollForward": "latestPatch",
    "paths": [
        ".fallout/temp/dotnet-win",
        ".fallout/temp/dotnet-unix",
        "$host$"
    ]
  }
}

This tells Rider/VS/IDE to look into the locally install directories first and then what's installed on the host.
Works locally, in CI/CD with pre-installed SDK and in CI/CD with no matching SDK installed (since build.{sh,ps1} installs it and will be picked up)

I propose to add this to the global json, since it doesn't hurt anyone, but restores a fallback path for local dev.

Could you help with a pull-request?

Yes
