Cannot access method 'Handle' MediatR due to its protection level .net using xunit
Declare the handler variable as of type IRequestHandler<AddUserDeviceCommand>.
AsyncRequestHandler<TRequest> implements IRequestHandler<TRequest>, via which you can access its Handle method.
AddUserDeviceCommand command = new AddUserDeviceCommand(
data.AppBuildNo, data.Width, data.Height, data.PlatformInfo, data.DevicePlatform
);
IRequestHandler<AddUserDeviceCommand> handler = new AddUserDeviceCommandHandler(
userservice.Object, repoacc.Object
);
await handler.Handle(command, CancellationToken.None);
