Capitalization matters when compiling, the file is Program.cs not program.cs. Capitalizing Program should solve your problem.

mcs Program.cs

Happened to me too, the one thing not mentioned in the directions is you need to make sure that you are in the FitnessFrog directory, your command prompt should look like this :


if you just have this for a command prompt:


then you need to go to that directory by entering:

treehouse:~/workspace$cd FitnessFrog

I can't even do this. It tells me no such directory exists...

Follow-up: It seems that this may have been because in the video the FOLDER is named "FitnessFrog", whereas my workspace is named "C# Basics - Start Coding" by default. At this stage (it's my first day on Treehouse) I don't know how to change the folder name, or even if it's necessary. The program was able to compile in the end without changing the directory. My problem, it turns out, was that I hadn't saved the project.

I had the same problem, thank you for this thread! The console was returning an error message which said error CS5001 ' Program.exe does not contain a static 'Main' method suitable for an entry point'. I pressed 'save' within the file menu, and all was solved.
