What's solid code? Writing reliable code is known as a query approximately what the code is making an attempt to resolve. (And solid code isn't to be harassed with styles simply because no longer all items of excellent code are styles. ) We debate approximately solid code simply because there isn't only a unmarried piece of excellent code, yet such a lot of reliable items of code.

NET version and settings, may be lost or even rethrown on an unexpected thread, terminating the process. We’ll see better ways to do this in Chapter 7. Async Method Return Types There are three return types that a method marked async may have: • void • Task • Task
Despite that, async is not part of the signature of the method, in terms of overriding other methods, implementing interfaces, or being called. The only effect that the async keyword has is on the compilation of the method to which it is applied, unlike the other keywords that are applied to a method, which change how it interacts with the outside world. Because of this, the rules around overriding methods and implementing interfaces completely ignore the async keyword. class BaseClass { public virtual async Task
Task; } Of course, this is such a useful little tool that it’s provided in the framework. Delay, and of course the framework version is more powerful, robust, and probably more efficient than mine. Waiting for a Collection of Tasks As we saw back in “Task and await” on page 20, it’s very easy to run multiple asynchronous operations in parallel by calling them in turn, then awaiting them in turn. What we’ll find out in Chapter 9 is that it’s important that we await each and every Task that we start, otherwise exceptions can get lost.
