Web Development on Mono

Background

Today I decided that I wanted to try out deploying a ASP.NET MVC + Web Api application on Ubuntu.

Why do I want to do that? Well I have always loved C# and .NET, however I have never really enjoyed the Microsoft ecosystem. I am glad that Mono is around and have often wondered What if C# and .NET had targeted all platforms?

I wanted to get MVC 4 and Web API to work correctly. So after spending a few hours on it I thought I would share it with you all.

Process

Below will outline the steps that I took to get this working. I will leave the blood and tears to myself.

Preliminary

The first thing I did was to get vagrant to work. This makes it easier to provision a virtual machine on my mac book pro. The image that I used was Ubuntu Server 12.10 amd64 Minimal (VirtualBox 4.2.6). I created a Vagrantfile that contained the following code:


Vagrant.configure("2") do |config|
  config.vm.box = 'quantal64'
  config.vm.provision :shell, :path => 'bootstrap.sh'
  config.vm.network :forwarded_port, guest: 80, host: 9000
end

The bootstrap.sh contained the following:


#!/usr/bin/env bash

apt-get update
apt-get install -y git
apt-get install -y nginx
apt-get install -y g++
apt-get install -y gettext
apt-get install -y pkg-config
apt-get install -y automake

These packages will be used to build mono and the web-server  Once you have all this set up is just as easy as saying vagrant up and vagrant ssh

Compiling Mono

Once you have logged-in into the box you will run the following commands:

• wget http://download.mono-project.com/sources/mono/mono-3.0.7.tar.bz2
• tar -xvjpf mono-3.0.7.tar.bz2
• cd mono-3.0.7
• ./configure --prefix=/usr/local
• make
• sudo make install

Once all that finishes you will need to get web-sever to work:

• git clone https://github.com/mono/xsp
• cd xsp
• ./autogen.sh --prefix=/usr/local
• make 
• sudo make install

To test if it works create yourself a simple example project or use the one I made. To get the development web server up run sudo xsp4 --port 80 and go to http://localhost:9000/api/service/test. You should see the following:

Future

I will be going through some of the MVC 4 and Web API 4 features to make sure it all works. Once that is done I will try to do this on AWS by creating an AMI so that I can test some release processes. Thanks for reading and hope this was just as exciting for you as it was for me.

Is NuGet really open source?

So about 6 months ago I submitted a patch to try to fix the out of memory exception that we were getting with NuGet, due to having large packages.

The reason I discovered this was because I wrote a tool that emulated apt-get using NuGet that is on my github. I really saw the potential with using nuget for .NET projects.

Unfortunately my patch got rejected after a 6 month code review with the following message:

To update everyone on this issue, I'm planning to reduce the overall usage of MemoryStream in NuGet.Core. In many cases, we load the package contents into memory unnecessarily, hence the OOM exception. It will address the issue better than trying to band-aid it with writing to a temporary file, which could potentially affect perf. I'm sorry to decline the pull request, but rest assured that the OOM exception will get fixed in 2.3.

So why the disappointment? Well rather than work in a open source way Microsoft decides that they can do it better. It is just sad that this software giant does not understand OSS.
