When should ConfigureAwait be true?

When should ConfigureAwait be true?

A situation to use ConfigureAwait(true) is when performing await in a lock, or using any other context/thread specific resources. This requires a synchronization context, which you will have to create, unless you are using Windows Forms or WPF, which automatically create a UI synchronization context.

What does ConfigureAwait false mean?

ConfigureAwait(false) involves a task that’s already completed by the time it’s awaited (which is actually incredibly common), then the ConfigureAwait(false) will be meaningless, as the thread continues to execute code in the method after this and still in the same context that was there previously.

Should I use ConfigureAwait false?

As a general rule, every piece of code that is not in a view model and/or that does not need to go back on the main thread should use ConfigureAwait false. This is simple, easy and can improve the performance of an application by freeing the UI thread for a little longer.

What is the default value of ConfigureAwait?

If the default behaviour was ConfigureAwait(false) , the textBox1.

What does task ConfigureAwait do?

ConfigureAwait(false) configures the task so that continuation after the await does not have to be run in the caller context, therefore avoiding any possible deadlocks.

Which do I use ConfigureAwait True or false?

The direct answer to this question is: – If you are a writing code for the UI, use ConfigureAwait(true).

What does ConfigureAwait mean?

false
ConfigureAwait(false) configures the task so that continuation after the await does not have to be run in the caller context, therefore avoiding any possible deadlocks.

What does ConfigureAwait true do?

Is ConfigureAwait false faster?

If resuming on the right thread/synchronization context does matter, ConfigureAwait(false) will break your code, and then it doesn’t matter how fast it could have been.

Do you need ConfigureAwait in .NET core?

NET Core you won’t need to spread ConfigureAwait(false) all over your code. Almost! This is almost true, it is still recommended the utilization of ConfigureAwait(false) for libraries as a fallback if those libraries are used within a legacy framework. But for most of the cases yes, in .

Should I use ConfigureAwait false in asp net core?

What is async and await C#?

The async keyword turns a method into an async method, which allows you to use the await keyword in its body. When the await keyword is applied, it suspends the calling method and yields control back to its caller until the awaited task is complete. await can only be used inside an async method.

What is the difference between configureawait and configureawaitawait?

ConfigureAwait (true): Runs the rest of the code on the same thread the code before the await was run on. ConfigureAwait (false): Runs the rest of the code on the same thread the awaited code was run on. If the await is followed by a code that accesses the UI, the task should be appended with .ConfigureAwait (true).

Do I need configureawait(false) to avoid result/Wait-based deadlock?

@JonathanRoeder: Generally speaking, you shouldn’t need ConfigureAwait(false)to avoid a Result/Wait-based deadlock because on ASP.NET you should not be using Result/Waitin the first place. – Stephen Cleary Sep 9 ’14 at 18:57

What is httpcontext current in await?

HttpContext.Currentis flowed by the ASP.NET SynchronizationContext, which is flowed by default when you await, but it’s not flowed by ContinueWith. OTOH, the execution context (including security restrictions) is the context mentioned in CLR via C#, and it isflowed by both ContinueWithand await(even if you use ConfigureAwait(false)).

Is it possible to await a function in ASP NET API?

However, with ASP.NET Web Api, if your request is coming in on one thread, and you await some function and call ConfigureAwait(false) that could potentially put you on a different thread when you are returning the final result of your ApiController function. Actually, just doing an awaitcan do that.
