The preceding code demonstrates a bad practice: constructing synchronous code to perform asynchronous operations. As written, this code blocks the thread executing it from doing any other work. It won't be interrupted while any of the tasks are in progress. It would be as though you stared at...

Our digital world functions because of programming, but if the correct operations and programs weren't used together, confusion and bad user experiences would result. Our digital world might spiral into a crazed, frantic frenzy if operations rely unnecessarily on asynchronous programming. Our digital ...
// Warning: bad code! [TestMethod] public void IncorrectlyPassingTest() { SystemUnderTest.SimpleAsync(); } Unfortunately, this unit test doesn’t actually test the asynchronous method correctly. If I modify the code under test to fail, the unit test will still pass: ...
Now the bad news. For BeginWrite not to use another thread from the pool, the isAsync parameter to FileStream's constructor must be set to true, as I've done in my example. However, a little-known consequence of using FileStream.BeginWrite to initiate an asynchronous write is that there...
While one might argue that universal handlers like this one are bad programming practice, such code is quite reasonable in a sequential setting, where one understands exactly which exceptions the expression e might raise. A solution is to de- fine two datatypes, exceptions and alerts, with a ...
In modern programming languages like Kotlin, which support functional programming features, you can do the same with alambdaexpression. In the previous example, you could pass the lambda to the upload function as a callback. The lambda would then contain the code to execute when the uploa...
Although making good use of our new-found silicon real estate requires improvements in software, a lot of programming languages have already started down this path by adding features that help with parallel execution. In fact, they’ve been there for years waiting for us to take advantage. So...
Whew#AsyncExpertcourse from@dotnetosorgis intense and full of useful content. Feel like I actually understand tasks in dotnet the good, the bad and the ugly! — Romanx (@ItemLevel1)July 28, 2020 You and all team should be proud! The course content is unbelievable amazing !!! Thks for...
In web apps that’s impractical and bad design, so this method gets rid of the unneeded state tracking and improves performance in the process. Making Razor Pages action methods asynchronous Now that you have an asynchronous repository method you can use it in a page model. The Customers...
