Upgrading to MonoDevelop 5.1 in Linux Mint 16

Linux Mint, being based on Ubuntu, is stuck with an old 2.10.8.1 version of Mono, and an equally old version of MonoDevelop. So, using this posting on stackoverflow, I've upgraded to the latest versions of Mono runtime and MonoDevelop.

First, the runtime:

sudo add-apt-repository ppa:directhex/monoxide

In Software Manager, edit Software source PPA's for monoxide, changing saucy to raring to select the 13.10 Ubuntu branch. Now upgrade:

sudo apt-get update && sudo apt-get dist-upgrade

At this point, I am running MonoDevelop 5.1, and I can compile and run desktop apps.
Next,  to use ASP.NET, we meed to get the web server running:

sudo apt-get install autoconf automake libtool g++ gettext libglib2.0-dev libpng12-dev libfontconfig1-dev
cd Git
git clone git://github.com/mono/xsp.git
cd xsp
./autogen.sh --prefix=/usr
make
sudo make install
sudo mkdir /etc/mono/registry
sudo chmod -R 0777 /etc/mono/registry

I can now create and run ASP.NET apps.  Check out my demo shopping cart app - Monomart.
