Fast Async Stream Copy
This is a simple code implementation to copy Streams leveraging the Async workflow. After the first read, the write and read processes are done in parallel. I also used an Array of Array as buffer to avoid false sharing memory. An other improvment option could be to increase the buffer size if the copy is done in same machine.

The Haskell const function
The const function is simple, but you can use it to make your code more legible. In this example we convert a unary function to a function of arity 2 (that ignores the second argument). Also by using the flip function from Haskell (which is equally easy to define) you can ignore the first argument.

WPF / SilverLight Converter II
version 1 is http://fssnip.net/62. This new version support convert from any existing function to a converter function by using composition and pipeline. The convert function is to make the function signature agree to the IValueConverter interface. You can add new functions in the FunctionLibrary module and reuse the class definition to reduce the coding effort. The first sample is to show how to make the converter pipeline work, the second one is a debugger converter used to debug the data binding problem.
