Change projects to target netcoreapp3.0 #3754
Description
As a part of only supporting .NET Core, we can change most projects to target netcoreapp3.0 instead of netstandard2.0.
This change applies to test projects, which no longer need to cross-target .NET Framework.
Remaining feature areas (I likely missed a few here, keep adding them ~Chris):
- Html
- Razor - make sure to ping @rynowak on this one. We're splitting code here into a new repo soon.
