Hydra version : 188.8.131.527 (purchased)
Plugin created in c# .net framework 4.7.2
Tested using both c# and Delphi 7 host.
Winforms Plugin created as per documentation with custom interface inherited from IHYCrossPlatformInterface
Visual plugin loads correctly into both D7 host and .net host.
The RemObjects.Hydra.CrossPlatform.IHYCrossPlatformHost in the plugin is always Null.
Tried creating a WPF host and the Host is correctly populated in the plugin and interface methods can be called.
