Compiler error: error CS2015: Source file `TreehouseDefense.exe' is a binary file and not a text file

I already worked through a bunch of errors but I can't get rid of this one.

error CS2015: Source file `TreehouseDefense.exe' is a binary file and not a text file

That file "TreehouseDefense.exe" is the output file, it's not one of the sources. So when you build the code, you want to be sure to tell the compiler that's where to put the output and not to use it as an input.

Typically, the build command would look like this:

$ mcs -out:TreehouseDefense.exe *.cs

If you still have trouble, show what you are using as the build command.

I got this error when I had a space between the "*" and ".cs".

mcs -out:TreehouseDefense.exe * .cs // Threw an error,
mcs -out:TreehouseDefense.exe *.cs  // did not.

The correct command (with no extra space) means "use every file that ends in ".cs" as an input", but the command with the space means "use every file as an input, and then read the file named ".cs" again".

Thanks! I was wondering what difference the space made.

mcs -out:TreehouseDefence.exe *.cs && mono TreehouseDefence.exe

Is still giving me this error. Hmm
