How to use operation inside proxy class as sync only? - wcf

Question

I followed article to include WCF service into my ASP.NET core application.
It seems that Generated Reference.cs file automatically included Async operations. Is it possible to make these operation sync only? Either in Reference.cs using them on client side.?
Generated Reference.cs file looks like follows-
//------------------------------------------------------------------------------

// Changes to this file may cause incorrect behavior and will be lost if
// the code is regenerated.

You can call async method synchronously and there are several ways to do this:
For Task<T> use:
var result = Task.Run(AsyncMethod).Result;
// if the Task fails, GetResult() will just throw an `AggregateException`
// or use
var result AsyncMethod.GetAwaiter().GetResult();
// if the Task fails, GetResult() will just throw the exception caused directly
For Task (not Task<T>) use:
AsyncMethod.RunSynchronously();
