In a first exemplary media implementation, one or more processor-accessible media include a build provider that is tailored for a particular file type, the build provider adapted to generate code from files corresponding to the particular file type and to contribute the generated code to a compilation. In a second exemplary media implementation, one or more processor-accessible media include processor-executable instructions that, when executed, direct a device to perform actions including: accepting multiple files, each file of the multiple files corresponding to a respective file type and including source code; associating a build provider with each file of the multiple files in accordance with the corresponding respective file type; ascertaining the source code of each file of the multiple files via the associated build provider; and compiling the ascertained source code of each file of the multiple files into an assembly.
