    async/await does not “release the thread”

    • 7 Comments

    .NET Extension methods from C++

    • 0 Comments
    Extension methods are a nice little feature now available in C# and VB.NET. They allow you to tack on new methods to existing classes for which you don’t own the original code. Now C++ does not support this natively and so I recently got bit when I was...
