Question 1

How do I build a simple MSI with WiX?

Accepted Answer

Follow the Quick Start guide in the documentation: create an XML .wxs file defining components, use candle.exe to compile it, then light.exe to link into an MSI. Visual Studio templates can speed this up for basic setups.

Question 2

Is WiX free for commercial projects?

Accepted Answer

No, WiX requires an Open Source Maintenance Fee for revenue-generating use, as stated in the README. This fee supports sustainability, so commercial users must become sponsors or pay separately.

Question 3

WiX or InstallShield: which is better?

Accepted Answer

WiX offers more control and is open-source with XML source code, ideal for automation and customization. InstallShield provides a graphical interface and is easier for beginners but is proprietary and costly. Choose WiX for flexibility and integration; InstallShield for rapid GUI-based development.

Question 4

How to add a custom action in WiX?

Accepted Answer

Define a CustomAction element in your XML with attributes like Execute and Return, then reference it in a sequence. You can write code in C# or C++ and package it with the installer, as shown in the custom action framework documentation.

Question 5

Can WiX handle .NET Core application installers?

Accepted Answer

Yes, WiX works with .NET Core by using heat.exe to harvest files from publish output and integrating custom actions. Ensure your installer targets the appropriate runtime and includes necessary dependencies for silent installs.

Question 6

What's the deal with the Open Source Maintenance Fee?

Accepted Answer

It's a fee required for using WiX in revenue-generating projects, covering support and development. While the source is free, activities like downloading releases or opening issues need fee adherence, detailed in the OSMFEULA.

Question 7

How to automate WiX in GitHub Actions?

Accepted Answer

Use the WiX NuGet package in your workflow, run candle and light commands via PowerShell or bash scripts. The README highlights command-line tools for CI/CD, making it straightforward to integrate with build automation.
