Data Entry in registry is Not working when Use Async/Await specially in API

Question

public async Task AddValueInRegistry() {
       await Task.Run(() => {
           RegistryKey key = Registry.CurrentUser.CreateSubKey(@"Software\Shashi3\Stage1\Stage3", true);
           key.SetValue("Test Key", 2);
           key.Close();
       });
    }

Consider the above method when I run it it creates directory in registry but not data entry.

Answer 1

call AddValueInRegistry by using one of the following methods:

AddValueInRegistry().Wait(); 

or

public void async UpperMethod()  {
    await AddValueInRegistry();
}
