C#
So I decided to get a little more... creative with my entry. The Brainfuck code is embedded into the C# as the various operators (not in comments or in hardcoded strings), while the C# code itself operates on a similar principal to the way Brainfuck prints characters (meaning there are no hardcoded strings, and C# generates each individual character as an integer then casts it to a char when printing).
I'm sure I could have made this more elegant, but it took me long enough to finish as it is.
Everything was tested on this JavaScript Brainfuck interpreter by Cal Henderson and with Visual Studo 2012's C# compiler (targeted at .NET framework v4.0).

This is the original Brainfuck code I wrote for this challenge:

When running the C# code through a Brainfuck interpreter, you end up with the following commands (notice the addition of the square brackets at the beginning, these are from the array declaration and don't do anything, since the cell under the memory pointer in the array will already be 0):

code-golf
is the best tag for this challenge. IMHOpopularity-contest
would be better. \$\endgroup\$
