WixSharp (WixSharp) - managed interface for WiX

Framework for building a complete MSI or WiX source code by using script files written with the C# syntax.

In July 2014 WixSharp was migrated to CodePlex WixSharp and re-released under MIT license. It was subsequently migrated from CodePlex to GitHub. You can still find old releases and some useful content from the past discussions on CodePlex.

Project Description

WixSharp is a member of the CS-Script family. WixSharp allows building a complete MSI or WiX source code by executing script files written with the plain C# syntax. WixSharp engine uses a C# class structure to mimic WiX entities and their relationships to produce a valid deployment model.

WixSharp answers many MSI authoring challenges. It solves the common MSI/WiX authoring limitations in a very elegant yet unorthodox way. WixSharp follows the steps of other transcompilers like Script#, CoffeeScript or GWT by using source code of a more manageable syntax (C# in this case) to produce the desired source code of a less manageable syntax (WiX). A "more manageable syntax" in this context means less verbose and more readable code, better compile-time error checking and availability of more advanced tools.

WixSharp also removes the necessity to develop MSI sub-modules (Custom Actions) in a completely different language (e.g. C++) by allowing both the components and behaviour to be defined in the same language (C#). This also allows for a homogeneous, simplified, and more consistent source code structure.

Overview

NOTE: WixSharp releases come in two streams: Releases v1.* use the WiX3 toolset to author msi setups, and v2.* use WiX4+. For the time being, the two streams will be maintained in parallel, but when WiX4/5 becomes mature enough, the WiX3 stream will be obsolete.

If you use WiX4+ stream, you need to install .NET SDK (not .NET Framework SDK) installed in your build environment. Visual Studio 2022 comes with .NET SDK already. The need for .NET SDK is dictated by the method WiX vendor distributes WiX compiler and its dependencies (via dotnet tool). WixSharp fully adheres to this approach. Even though it provides a workaround for the absence of .NET SDK.

If you are planning to use WixSharp on Linux, you may find this article useful. Please note that WixSharp builds MSI deployment packages and while MSI can be built on Linux it cannot be run on Linux as MSI is a pure Windows technology.

Please note that WixSharp NuGet packages (for both WiX3 and WiX4) are targeting .NET Framework only. This is because WiX does not support integration with any other .NET flavours but .NET Framework only.

You can find the instructions on how to author MSI setups with WixSharp in the Documentation section. And this section only highlights some of the available features.

If you prefer a manual approach you can use the Visual Studio console application project and NuGet package as the starting point. image <br> However a simpler approach is to use Visual Studio WixSharp Project Template extension. Read more about the WixSharp VS templates here.

WixSharp allows a very simple and expressive definition of deployment. This is an example of a simple WixSharp script:

using System;
using WixSharp;
 
class Script
{
    static public void Main(string[] args)
    {
        var project = new Project("MyProduct",
                          new Dir(@"%ProgramFiles%\My Company\My Product",
                              new File(@"Files\Docs\Manual.txt"),
                              new File(@"Files\Bin\MyApp.exe")));
 
        project.GUID = new Guid("6f330b47-2577-43ad-9095-1861ba25889b");
 
        Compiler.BuildMsi(project);
    }
}

One of the most intriguing features of WixSharp is the ability to define/implement managed Custom Actions directly in the script file:

using System;
using System.Windows.Forms;
using WixSharp;
using Microsoft.Deployment.WindowsInstaller;
 
class Script
{
    static public void Main(string[] args)
    {
        var project = new Project("CustomActionTest",
                          new Dir(@"%ProgramFiles%\My Company\My Product",
                              new DirFiles(@"Release\Bin\*.*")),
                          new ManagedAction(CustomActions.MyAction));
 
        BuildMsi(project);
    }
}
 
public class CustomActions
{
    [CustomAction]
    public static ActionResult MyAction(Session session)
    {
        MessageBox.Show("Hello World!", "Embedded Managed CA");
        session.Log("Begin MyAction Hello World");
 
        return ActionResult.Success;
    }
}

Another important feature is the support for custom UI including WPF external UI: image
