Thanks for dotnet core 3.0

[fluffynuts]

Just wanted to say thanks for the dotnet core 3.0 release & ask if it's possible to have multiple runtimes side-by-side? I mean to update projects, but in the meantime, I also have to be able to build existing ones, but I see messages like:

  The specified framework 'Microsoft.NETCore.App', version '2.0.9' was not found.
    - The following frameworks were found:
        3.0.0 at [/opt/dotnet_core/shared/Microsoft.NETCore.App]
  
  You can resolve the problem by installing the specified framework and/or SDK.
  
  The .NET Core frameworks can be found at:

This is possible since about a week, just try it out :)

You can request an explicit slot using emerge dotnetcore-sdk-bin:2.2

Thanks! Most excellent and confirmed working :D

Unfortunately, to resurrect something quite old, slotting doesn't seem to be able to solve more recent requirements of side-by-side, specifically net7.0 with net6.0 - eg #516:

❯ emerge dotnet-sdk-bin:6.0
Calculating dependencies... done!
Dependency resolution took 10.42 s.

I feel like slotting is probably the correct way to solve this, but it's not currently possible.

[filmor]

It is. You just need to ensure that exactly one version has USE=dotnet-symlink. It's not ideal because the slotted /usr/bin/dotnet will by default not be able to see the other installed frameworks, but that's fixable with a few more symlinks :)

[fluffynuts]

There was another issue where someone was asking about 6.0 in 7.0 - I've mentioned this discussion and the resolution there.

Also, I've learned a little more about slotting, which is a very cool feature of portage that I've never really needed before, tho have read about before.

[slonopotamus]

the slotted /usr/bin/dotnet will by default not be able to see the other installed frameworks, but that's fixable with a few more symlinks :)

Is there any tracking issue for this?

this would also make my life much easier
