JSON Serialization in WCF and .NET 3.5

I just burned an hour chasing down a JSON serialization issue in .NET 3.5.  Watch out for trying to serialize DateTime values that are MaxValue or MinValue.  This is an issue whether you are using the DataContractJsonSerializer directly or if you are using a WebInvoke with response formatting set to Json.  The latter can be…

Maze Simulator for Robotics Studio

In my last post, I described the maze generator I developed in C#.  This was trivial to build as to be expected.  The larger challenge for me was to learn enough about the simulator in MSRS 1.5 to build a 3D maze and let me virtual robot navigate through it.  After a few more hours…

My team works with the…
