Background and Motivation

The VSTHRD103 analyzer exists and it is broadly valuable. We should promote this analyzer to be part of the standard set of analyzers that ship with the .NET SDK.

Examples of patterns that are flagged by this analyzer

Task DoAsync()
{
    file.Read(buffer, 0, 10);
}

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<T>.Result or Task.GetAwaiter().GetResult()
will produce this warning.

Solution

Await the async version of the method:

async Task DoAsync()
{
    await file.ReadAsync(buffer, 0, 10);
}
