How can I create an asynchronous method using reflection? Basically I need something like this: async public Task asyncmethod() { await something(); } but I need to do it with reflection.

I'm working on an ILGenerator extension to help emit IL fragments using Expression. Everything was fine, until I worked on the integer conversion part. There are something really counter-intuitive ...

Using the new async/await model it's fairly straightforward to generate a Task that is completed when an event fires; you just need to follow this pattern: public class MyClass { public event Act...

I'm trying to improve the performance of our application. We have a lot of Activator.CreateInstance calls that are causing some grief. We instantiate a lot of classes based on an interface (ITabDoc...

Using TypeBuilder, I'm building a class that implements an interface that contains a method. After implementing that method with ILGenerator, then I call TypeBuilder.CreateType() and everything goe...
