How Can I Synchronously Run Async Tasks in C#?

Use the Runsync auxiliary method to run asynchronous tasks simultaneously

asynchronous programming (using Async/Await) has a significant advantage in development. However, in some cases, asynchronous tasks need to be performed simultaneously. This article introduces the Runsync auxiliary method, which can perform the Async Task

method simultaneously to solve this demand.

To use Runsync, just add it to the code, as shown below:

Implement the details

<code class="language-csharp">customerList = AsyncHelpers.RunSync(() => GetCustomers());</code>

Runsync method runs by creating an exclusive synchronization context and setting it to the current context. This context allows processing messages and ensures synchronous execution of asynchronous tasks. To deal with any possible abnormalities, this method uses a private class named ExclusiveSyninizationContext, which expands the synchronizationContext.

In the context, the task was released, and the WorkiteMSWAITING event was set to send a signal, indicating that the project is waiting. Then, the BeginMessageloop method handles all the linked items until the task is completed. After the completion, the ExclusiveSyNChronizationContext will be restored and the results of the task will be returned.

The code provided is not owned by the author and is still under review. However, it proves that it is effective in various cases, including the situation of hanging the scheduling program. Conclusion

By using the RunSync auxiliary method, developers can perform asynchronous tasks simultaneously to expand the function of asynchronous programming. EXClusiveSynchronizationContext and message cycle processing ensure that the task is reliably and effective in sync.
