CA1849 is not raised by GetAwaiter().GetResult()

[jloscos]

Diagnostic ID : CA1849

Description

According to the documentation the CA1849 :

All methods where an Async-suffixed equivalent exists will produce this warning when called from a Task-returning method. In addition, calling Task.Wait(), Task.Result, or Task.GetAwaiter().GetResult() will produce this warning.

The warning is triggered as expected when calling .Wait() or .Result but not when calling .GetAwaiter().GetResult().

Steps to reproduce

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net10.0</TargetFramework>
    <EnableNETAnalyzers>true</EnableNETAnalyzers>
    <AnalysisLevel>latest</AnalysisLevel>
    <AnalysisMode>All</AnalysisMode>    
  </PropertyGroup>
</Project>

public static async Task<string> ReadFileAsync()
{
    // The following line does not trigger the CA1849 rule
    var content = File.ReadAllTextAsync("input.txt").GetAwaiter().GetResult();
    return content;
}

Expected Behavior

CA1849 is raised

Actual Behavior

No warning are raised
