You aren't able to use .net core versions previous to 3.0 due to the fact that Windows Desktop support is, in fact, a new feature to core 3.0.由于Windows 桌面支持实际上是核心 3.0 的新功能，因此您无法使用 3.0 之前的 .net 核心版本。
@madreflection has pointed out in comments that there is a designer for WinForms that will work in core 3.0, but it is currently in preview. @madreflection 在评论中指出，有一个WinForms 设计器可以在 core 3.0 中工作，但它目前处于预览阶段。 This may prove sufficient for your purposes in the interim, but you may be looking at sticking with Framework until the designer is out of preview.在此期间，这可能足以满足您的目的，但您可能会考虑坚持使用 Framework，直到设计器不再预览。
