In part 1, we set up TFS. In part 2, we configured our Linux build agent. Now in part 3, we'll be setting up DNX (the .NET Execution Environment) for Linux. Since DNX/ ASP .NET 5 is still in development, we'll be going against the latest dev branch for extra fun.

Firstup, we needtoinstall Mono,the open-source CLRandBCL implementation.
Run the followingcommandstogetthat processstarted.

sudoapt-getinstall mono-complete

Whenit's done,run mono--version

Now,a fewmore prerequisites.We have toinstall Libuvinordertotestthat DNX isworkingproperly,so
run these commands:
sudoapt-getinstall automake libtool curl
