I’ve been doing a bit of work with Solver Foundation lately and as I got to know the package it suddenly occurred to me Solver Foundation could be easily used to solve Sudoku puzzles.

This article contains materials for two talks that I had in November. First, I presented the F# plugin for MonoDevelop at the F# in Education workshop in Boston (using 3D functional library) and then I talked about agent-based concurrency (with Twitter and image processing examples) in London.

Earlier this week I gave a talk at the first London WebSharper User Group meetup about WebSharper 2.0 and some of its new features such as sitelets and the new Visual Studio templates. This was a longer, class-like talk with many technical points discussed - a great source of information for anyone interested in WebSharper.

We are making excellent progress on releasing WebSharper 2.0 in the coming weeks, and have just put out the first beta version of WebSharper 2.0, ready for some public testing and community feedback. Here are the links:

In this article, we look at the internals of asynchronous programming models in F# and a future version of C#. We compare the compilation in C# (based on state machines) and the compilation in F# (based on combinators) and we look at advantages and disadvantages of both of the approaches.
