 a seasoned *Merq* developer, this is a no-brainer, but for new developers, 
 it can be a bit puzzling:

 A code fix is provided to automatically implement the required interfaces 
 in this case:

 Likewise, if a consumer attempted to invoke the above `Echo` command asynchronously 
 (known as the [async over sync anti-pattern](https://devblogs.microsoft.com/pfxteam/should-i-expose-asynchronous-wrappers-for-synchronous-methods/)), 
 they would get a somewhat unintuitive compiler error:

 But the second error is more helpful, since it points to the actual problem, 
 and a code fix can be applied to resolve it:
