c# - Using async without await?

Question

Consider Using async without await.

think that maybe you misunderstand what async does. 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.

I want write a method that should run async but don't need use await.for example when use a thread

public async Task PushCallAsync(CallNotificationInfo callNotificationInfo)
{
    Logger.LogInfo("Pushing new call {0} with {1} id".Fill(callNotificationInfo.CallerId,
}

I want call PushCallAsync and run async and don't want use await.

Can I use async without await in C#?

Answer 1

If your Logger.LogInfo is already async this is enough:

public void PushCallAsync(CallNotificationInfo callNotificationInfo)
{
    Logger.LogInfo("Pushing new call {0} with {1} id".Fill(callNotificationInfo.CallerId,
}

If it is not just start it async without waiting for it

public void PushCallAsync(CallNotificationInfo callNotificationInfo)
{
    Task.Run(() => Logger.LogInfo("Pushing new call {0} with {1} id".Fill(callNotificationInfo.CallerId));
}
