关于[Release Candidate builds of Entity Framework Core 3.0 and Entity Framework 6.3 are now available]的摘要:
We previously said that preview 9 would be your last chance to test EF Core 3.0 and EF 6.3 before general availability. But it turns out that we made enough improvements to our libraries and across the whole of .NET Core 3.0 to justify publishing a release candidate build. Hence the packages for EF Core 3.0 RC1 and EF 6.3 RC1 were uploaded to nuget.org today.
