关于[Updates to .NET Core Windows Forms designer in Visual Studio 16.5 Preview 1]的摘要:
We are happy to announce the new preview version of the .NET Core Windows Forms designer, which is available with the Visual Studio 16.5 Preview 1. The big news is that the designer is now part of Visual Studio! This means that installing the .NET Core Windows Forms designer from a separate VSIX is no longer needed!
