Build an installer for .NET app that can run on Windows and OS X?

Question

I am surprised I could not find this question already asked, so if I simply missed it please notify promptly.

I need to write a very small, fairly simple application in .

Answer 1

You could try BitRock's InstallBuilder. From their website:

BitRock InstallBuilder is a development tool for building crossplatform installers for desktop and server software. With InstallBuilder, you can quickly create professional installers for Linux, Windows, Mac OS X, Solaris and other platforms from a single project file and build environment.

Answer 2

What you want is InstallAnywhere. It allows you to target multiple platforms with one installer project. It will help with dependencies and platform specific issues.

I've used it on LINUX/BSD/Windows deployment, and it worked beautifully. If you had X-windows, you got a GUI, if not a command line install. Windows installer worked with standard windows installer tech, and looked like a professional installer. It supports mac OS X as well. I highly recommend this software it does exactly what you want.

Answer 3

As other posters mentioned, BitRock InstallBuilder supports your target platforms of Windows, Linux and Mac. I want to add that it has been used by the Mono project itself for a while to distribute all-in-one binary installer for Mono runtime. It is also used by other successful Mono-based ISVs like Codice Software

For Windows, consider Windows Installer XML (WiX). For OSX, you need to generate a .app bundle. Here is an example using the nant tasks included with the Monobjc project.

Here are some of the major issues you will face:

On Windows:

• Your installer will have to detect previous/old versions and close/uninstall/migrate as appropriate. Both NSIS and WiX have mechanisms for this.
• Your installer/app will have to be compatible with different versions of Windows (XP, Vista, 7), and different versions of .NET (2.0, 3.0, 3.5 eventually). Actually testing this is one of the more tedious tasks you face. I strongly recommend having a handful of clean virtual machine images around for this.

On OSX:

• You will most likely want to ship a standalone application bundle, meaning mono will be bundled within your .app. This will add ~50mb to your distributable.
• You will have to reference different versions of Monobjc to support OSX 10.4 and 10.5, you will need to configure your build to do this, as well as test both versions.
• Make sure that your c# code isn't using Windows/.NET specific calls by running the Mono Migration Analyzer (MoMA) on your codebase.

Upgrading:

You haven't mentioned how you plan to offer upgrades. NSIS and WiX have the capability to handle upgrades. Make sure you have your build versioning scheme worked out before your deploy the initial version. On OSX, Monobjc can integrate with Sparkle.

They deliver on the build once, run anywhere promise.
