.NET 5.0 Preview7 is now available, the penultimate preview version (before moving to RC). New features included are:
Default values for value type properties can be ignored when serializing
Can handle circular references when serializing
Performance enhancement
Garbage Collection improvements
RyuJIT improvements
Microsoft says individual files and ARM64 intrinsics are the two feature areas that will take the longest to complete, but are expected to be implemented in Preview 8. In addition, ASP.NET Core and EF Core have also been released simultaneously.
