System.InvalidOperationException

No service for type 'MediatR.Mediator' has been registered.

An unhandled exception occurred
Exception source not available.

Solution 

I changed the mediatR registeration in my startup file to

services.AddMediatR(typeof(Startup).GetTypeInfo().Assembly);

from

services.AddMediatR(typeof(Startup).Assembly);
