I have created an image classifier using ML.Net Model Builer in Visual Studio on Windows 10. It has been compiled in to a Console application. This runs fine on the development machine and other Windows 10 machines. I need to deploy it to a Windows 2012 R2 server but when I start the application I get this error message:
System.Reflection.TargetInvocationException: Exception has been thrown by the ta
rget of an invocation. ---> System.Reflection.TargetInvocationException: Excepti
on has been thrown by the target of an invocation. ---> System.Reflection.Target

Can anyone suggest how I can fix this?
Thanks
I was stuck in the same issue.
The solution was to Add Feature "Desktop Experience", which is not by default included in W2012 installation.
I hope that helps in your case!
