Feature Request: Add Interface validation on GetService calls to check if an interface is passed

[SimonDarksideJ]

Currently the GetService / TryGetService calls on the service manager accept any type when querying for a service, however, only interfaces should be passed to query for registered services.

So if a concrete type is passed, the service obviously cannot be resolved as the framework is interface dependent, but the consumer is unaware of the issue and this can lead to confusion.

I'd go even further. Only interface types that are based on IService should be passed and valid for those APIs
