Dotnet 5 non-visual plugin error calling from Delphi in hydra v6.6

Hi,

Have you read the NonVisual Plugins (.NET 5+) article ?

Just checked - 6.6.0.1309 is correctly installed to GAC.

we ship nuget package - C:\Program Files (x86)\RemObjects Software\Packages\RemObjects.Hydra.6.6.0.1309.nupkg. it contains all required dll for .NET 5+ plugins.

Check this example -
testcase.zip (17.8 KB)

Note: it uses .NET 6 because .NET 5 in VS2022 is deprecated but you can easily change it to .NET 5 if you are using VS2019.
