How Can I Synchronously Run Asynchronous Methods in .NET?

<.> Simultaneous running asynchronous method in .NET: TASK

When using asynchronous code in .NET, the asynchronous method may be performed synchronously for specific reasons. To this end, you can use a variety of technologies to achieve this.

Asynchelpers.runsync method

A general solution is to use the method. This method allows you to perform the asynchronous Task method simultaneously, whether there is a return value. Use this method:

No return value: AsyncHelpers.RunSync Call

1. There is a return value: Use grammar , where AsyncHelpers.RunSync(() => GetCustomers()); is your asynchronous method.
2. Customized synchronous context method AsyncHelpers.RunSync(() => GetCustomers()); GetCustomers() Another method involves the use of custom synchronization context, especially
. This method establishes a dedicated synchronization context, allowing you to run asynchronous tasks synchronously. To achieve this purpose:

Create a instance, and use to set it to the current synchronization context.

Use to publish asynchronous tasks to the context of synchronization.

ExclusiveSynchronizationContext Use MESSAGE LOOP.

After the asynchronous task is completed, use
1. to end the MESSAGE LOOP. ExclusiveSynchronizationContext SynchronizationContext.SetSynchronizationContext(syncContext); Use to reset the context to its original value.
2. syncContext.Post(async _ => { ... }, null); Precautions
3. syncContext.BeginMessageLoop(); Although these methods provide solutions, it should be noted that the synchronous execution asynchronous code may cause performance decline and potential deadlock. Therefore, it is recommended to use these technologies with caution, and only use it when absolutely necessary.
