Calling an asynchronous method without await is perfectly fine. Using await and async will keep an app responsive but causes more complexity, especially when exceptions are raised in a sub more so than a function. If it works now, leave it be, if you are unhappy with "now" then the caller needs to have async keyword and an await for a task.
What happens if you mark a method async but don't use await?
Is Logger.LogInfo synchronous?
Is async a void event handler?

Can you use async without await C?
The warning is exactly right: if you mark your method async but don't use await anywhere, then your method won't be asynchronous. If you call it, all the code inside the method will execute synchronously.
Can you call an async method without await?
The current method calls an async method that returns a Task or a Task
Is await async necessary?
Because await is only valid inside async functions and modules, which themselves are asynchronous and return promises, the await expression never blocks the main thread and only defers execution of code that actually depends on the result, i.e. anything after the await expression.
Can we use only async without await C#?
This is possible. The async modifier tells the program that this is an asynchronous operation. Awiat will suspend the execution of the code in async, wait for the result after the await expression, skip the async function, and continue executing the following code. Alternatively, you can use Task instead.
What happens if you don't await a promise?
Otherwise, if you don't use it, nothing good or bad will happen by default - the code inside the promise will still run, but nothing will happen when you call resolve . If you call reject , however, then nothing will handle the rejection; which is bad, as it throws an error on most platforms.
Does await make it synchronous?
Async/await helps you write synchronous-looking JavaScript code that works asynchronously. Await is in an async function to ensure that all promises that are returned in the function are synchronized. With async/await, there's no use of callbacks.
Which is better async await or promise?
Async/Await is used to work with promises in asynchronous functions. It is basically syntactic sugar for promises. It is just a wrapper to restyle code and make promises easier to read and use. It makes asynchronous code look more like synchronous/procedural code, which is easier to understand.
Which is better async await or then?
Async/await and then() are very similar. The difference is that in an async function, JavaScript will pause the function execution until the promise settles. With then() , the rest of the function will continue to execute but JavaScript won't execute the . then() callback until the promise settles.
Do I have to use await?
async And await Finally, when returning a Promise inside an async function, you don't need to use await . So the following is acceptable syntax. However, there's one exception to this rule: you do need to write return await if you're looking to handle the Promise being rejected in a try... catch block.
When should I use async await C#?
The main benefits of asynchronous programming using async / await include the following: Increase the performance and responsiveness of your application, particularly when you have long-running operations that do not require to block the execution.
Is async await blocking C#?
The await operator doesn't block the thread that evaluates the async method. When the await operator suspends the enclosing async method, the control returns to the caller of the method.
What are async methods in C#?
An async method runs synchronously until it reaches its first await expression, at which point the method is suspended until the awaited task is complete. In the meantime, control returns to the caller of the method, as the example in the next section shows.
How do you call async function without await Python?

What is the purpose of ConfigureAwait ()?
ConfigureAwait(continueOnCapturedContext: false) is used to avoid forcing the callback to be invoked on the original context or scheduler. This has a few benefits: Improving performance.
What happens if you await a non async function Python?
No other code can run while that's happening. If await was allowed in a non-async function, it would have to block execution of all other code until the Promise is resolved/rejected.
How to safely call an async method in C# without await
Stack Overflow for Teams is moving to its own domain! When the migration is complete, you will access your Teams at stackoverflowteams.com, and they will no longer appear in the left sidebar on stackoverflow.com.. Check your email for updates.
How can I await an async method without an async modifier in this ...
You can access .Result or use .Wait(), but you need to know how the task is implemented first.In particular, you need to know whether it uses sync-context. The reason this is important is that if it does this could deadlock immediately, because some sync-contexts need the calling context to exit completely (for example, MVC's sync-context needs to leave the controller's action method).
Asynchronous Method Without async in C# | the-drizzle
This happens because the HttpClient is disposed before the request made ever completes, thus canceling any ongoing requests.. Conclusion. Check out more subtle pitfalls of omitting async/await in this article by Stephen Cleary.. Equipped with this new information, I would recommend against removing the keywords by default. As they say, premature optimization is the root of all evil. 😅 That ...
C# Language Tutorial => Returning a Task without await
Example. Methods that perform asynchronous operations don't need to use await if:. There is only one asynchronous call inside the method; The asynchronous call is at the end of the method
Async And Await In C#
Basics of C# async await. In this article, you'll learn what C# async and C# await keywords are and how to use async and await in C# code. Nowadays, Asynchronous programming is very popular with the help of the async and await keywords in C#.
Why is C# 5.0 async?
The reason for async in C# 5.0 is so you can await a result. This method is not actually asynchronous, but simply called at a time so as not to interfere too much with the current thread. Perhaps it may be better to start a thread and leave it to finish on its own. Share. Improve this answer.
What to do if you don't want to wait for the result?
If you don't want to wait for the result, the only option is to ignore/suppress the warning. If you dowant to wait for the result/exception then MyAsyncMethod().Wait()
Why pass action onexception to call?
Passing the action onException to the call ensures that you get the best of both worlds - no need to await execution and slow your users down, whilst retaining the ability to handle the exception in a graceful manner.
Does GitHub remove warnings?
It doesn't do anything, it's just a trick to remove the warning. See github.com/microsoft/vs-threading/blob/master/src/…
Can you wait for an exception in MyAsyncMethod?
This will allow you to deal with an exception on a thread other than the "main" thread. This means you don't have to "wait" for the call to MyAsyncMethod () from the thread that calls MyAsyncMethod; but, still allows you to do something with an exception--but only if an exception occurs.
Is "continue with" the same as "try await"?
The ContinueWith version is not the same as the try{ await }catch{} version. In the first version, everything after ContinueWith() will execute immediately. The initial task is fired and forgotten. In the second version, everything after the catch{} will execute only after the initial task is completed. The second version is equivalent to "await MyAsyncMethod().ContinueWith(t => Console.WriteLine(t.Exception), TaskContinuationOptions.OnlyOnFaulted).ConfigureAwait(fals);
Is Async still Promise based?
It turns out all of the above combinations are possible, because async/await is still Promise-based under the hood:
Can you declare getPromise with async?
So can we declare getPromise () with the async keyword (snippet 4) and call it with the then clause (snippet 2) ? Yes, that works too.
Can you call a promise with await?
But if we declare getPromise without the async keyword (snippet 3), we can still call it with the await keyword. The reason being is getpromise () returns a Promise object. If a function returns a Promise, we can call it with await. So snippet 3 and snippet 1 still work together.
Can you declare a function as async?
We can declare a function as asyncwithout using any await. In this case, the execution is not paused and your code will be executed in a non-blocking manner (asynchronous - no waiting). It is the same as not declaring that same function with async.
Can you remove asynckeyword before f1?
You can remove asynckeyword before f1and still get the same result.
Can we await a function that returns a promise?
Since asyncis still promise-based, we can awaita function that returns a promise, even when that function is not an asyncfunction:
Does foreachdoes wait for promises?
Here foreachfunction takes a callback and execute it synchronously, as foreachdoes not wait for promises.
Can an async function contain a await expression?

What is async and await in C#?
Async and await in C# are the code markers, which marks code positions from where the control should resume after a task completes.
Which NET Framework supports async?
There are some supporting API's from the .NET Framework 4.5 and the Windows runtime contains methods that support async programming.
Can we run all methods parallelly?
We can run all the methods parallelly by using simple thread programming, but it will block UI and wait to complete all the tasks. To come out of this problem, we have to write too many codes in traditional programming, but if we use the async and await keywords, we will get the solutions in much less code.
Can you use async and await in C#?
We can use async and await keywords in C# to implement async programming in this easy way,
What happens if you mark a method async but don't use await?

Is Logger.LogInfo synchronous?
If Logger.LogInfo is a synchronous method, the whole call will be synchronous anyway. If all you want to do is to execute the code in a separate thread, async is not the tool for the job. Try with thread pool instead:
Is async a void event handler?
If you calling function is a void event handler, you're good. The async call will happen to some degree (namely File.WriteAsync) in the background. You do not expect any result in your control flow. That is fire and forget.
