Unit Testing Code Coverage for WebService Method including async methods

Question

I just need information about code coverage of webservice method that includes Async Methods as well.

Suppose, I have one method written in WebService, MethodOne(string Value) and I have written TestMethod to check code coverage for this method,

When I run Test and check in code coverage, it showing me something like

MethodOne(string) 100%

MethodOneAsync(string) 0%

MethodOneAsync(string,object) 0%

so because of Asynchronous methods, I can not verify the actual code coverage of my projects, I want to cover these kind of methods as well in my code coverage.

I researched on google and read many articles but didn't get a valuable code, I have written following code as well but it doesn't help as well.

public async void TestMethod1Async()
{
    bool isValue = await System.Threading.Tasks.TaskEx.Run(() => target.IsAccountDisabled(Guid.NewGuid()));
    Assert.IsFalse(isValue);
}

You can write asynchronous unit tests to test asynchronous methods.

Asynchronous unit tests must be async Task.
