It is a commonly used type when WinForms PropertyGrid control is in use, as custom collection editor is needed to edit custom collection types.

It is not yet available in .NET Core 3.0 Preview 1.

ℹ See dotnet/core-sdk#79 (comment) for an in-depth explanation of why we need to ship these types for our end users to use at runtime.

Same here...
Trying to test our WinForms stuff in .NET Core 3.0 and hitting up on these missing APIs as part of property-grid related runtime support.

In my case the missing types are:

  • CollectionEditor
  • ObjectSelectorEditor

Sure. Editors were ported as prioritized. We will get these ported as soon as possible.
