Description

• our projects target netcoreapp2.0
• .NET SDK 2.x versions are out of support

As a result, developers are required to use an out-of-support version of .NET SDK.

.NET Framework Support Policy: https://docs.microsoft.com/en-us/lifecycle/products/microsoft-net-framework

Action Items:

• Switch libraries to netstandard2.0
• Switch legacy libraries to the supported version of the .NET Framework
• Switch csproj files to the new SDK-based format
• Fix examples
• Remove all conditional compilation ('#if')
• Update build script
  • "dotnet build" can be used to build everything, including Full Framework solution

  • "dotnet pack" can pack NuGet packages
    • Get rid of nuspec files
