Await an async function from setter property

I need to await to an async function from a property setter method.

public String testFunc()
{
get
{

}
set
{
    //Await Call to the async func <asyncFunc()>

}
}

I understand we should not make async properties, so what is the optimal way to do this.

You can't use async function with property

Alternative Can use Result Property

public string UserInfo
{
    get => GetItemAsync().Result;
}

Use

public bool SomeMethod
{
  get { /* some code */ }
  set
  {
    AsyncMethod().Wait();
  }
}
public async Task AsyncMethod() {}

You can't make async properties and you shouldn't want to - properties imply fast, non blocking operations. If you need to perform a long running activity, as implied by you're wanting to kick of an async operation and wait for it, don't make it a property at all.

Remove the setter and make a method instead.
