How to package a Mono (.NET) applications for Debian-based Linux in command line. Packaging process can be easily automated on Continues Integration Server.

debian_package

Package building workflow is quite simple:

  • Assign a version number to a .NET assembly code
  • Build binaries
  • Copy binaries to package folder and build deb-package with the same version as an assembly

Build process will be controlled by MSBuild project file and run from a continues integrations server. MSBuild on Mono platform is substituted by xbuild utility.

Sample solution is available for download here https://github.com/mchudinov/PackagingMono. Solution is compatible with Visual Studio 2012, MonoDevelop/Xamarin Studio 5.

This is my third blogpost about automation of development workflow with Mono. Automated building and versioning were covered in my previous posts:

Versioning of .NET assemblies

Leave a reply

I use four-parts version pattern that looks like: {Major}.{Minor}.{Date (MMdd)}.{Build Number}

An example version in this format would look like: 1.7.1028.37, which breaks down into being the first major release, seventh minor release, built on 28 October, and has been the 37th build for v1.7. Every time assembly is rebuild build counter increases.

1. Building in command line

There are two standard command line building tools for .NET: MSBuild on Windows and xbuild on Linux/Mono. xbuild build files are compatible (with some exceptions) with MSBuild files.

We need at least 4 simple steps (targets as they called in MSBuild terminology) to build a .NET solution:

  • Clean
  • Restore NuGet packages
  • Build binaries
  • Run unit tests

Free .NET development software alternatives

The standard software stack for a .NET developer is

  • OS – desktop Windows
  • IDE – Visual Studio
  • Database – SQL Server

All these components are quite pricey. But there are free alternatives. And with my recent project I decided to use alternative software for development and production in .NET, all totally free.

  • OS – Linux Mint 17 (based on Debian/Ubuntu)
  • IDE – MonoDevelop
  • Database – MySQL Community Edition

Scrum: 4 typical mistakes

3 Replies

Some days ago I have been at Norwegian Development Conference in Oslo city (http://www.ndcoslo.com/). There were a couple of very good sessions about Scrum. I talked to people after those sessions, talked to Scrum Masters, developers, product owners about they experiences with Scrum. I figured out some typical mistakes that Scrum teams make. All these mistakes have actually the same root: Scrum practitioners forget about the reasons why we do Scrum.
