Real-world examples where C# 'out' parameters are useful?

Question

Output parameters are found all over the .NET framework. Some of the uses I see most often are the TryParse methods, which return a boolean (indicating whether or not the parse was valid) and the actual result is returned via the output parameter. While it's also very common place to use a class when you need to return multiple values, in such an example as this it's a little heavy handed. For more on output parameters, see Jon Skeet's article on Parameter passing in C#.
