Beginning in the fall of 2002, I started working on DrC#, an integrated development environment especially suited for beginners. Similar to DrScheme or DrJava, it was to provide an "interactions" window to shorten the edit-compile-run-debug cycle.

I worked on this project with other people in Rice's Programming Language Team (PLT), mainly Dennis Lu.

In the initial phases of development, we realized we needed to split the program into two separate processes, one for the IDE and one for the interpreter, so that the interpreter would not be able to kill the IDE if it was told to quit. My main task in the beginning of the project was to set up a remoting scheme that let a local program control the remote interpreter. The interpreter also had to be able to write to the local program's output.

In the later stages of the development of DrC# I wrote a plugin to the SharpDevelop IDE that provided the interactions window. I also modified a version of SharpDevelop to make it look more like DrJava. Here's a picture of the IDE:
