Adding an implicit cast functionality to Lazy<T> can give you an option to writing null checkers in your delayed instantiation properties. The problem Today in our project a colleague was cussing over the fact that he kept writing the same block of code over and over again when null checking a property with a backing field. Given the class Foo: private Foo oldFooProp; public Foo OldFooProp { get { if (oldFooProp == null) { ...

Have you ever wanted to dynamically choose from many potential implementations of some code? Would you like to have the power of metadata filtering and lazy instantiation of the selected implementation? Here is how to do just that using Managed Extensibility Framework (MEF) and also a neat trick to handle your implementation/metadata pairs that I recently put to good use. Code samples and optimizations follow so don’t worry; I won’t remain all theoretical in this post. (MEF is part of .NET Framework 4.0 but is available also on CodePlex for other releases – MEF Community Site.) Up front I...
