How Can I Debug Custom Actions in My Wixsharp Projects?

Debugging of custom operations in Wixsharp console environment

In Wixsharp, custom actions are compiled into .dll files, which makes it difficult to debug the code during the installation process. This article explores several ways to solve this problem.

First, you can set the package type to wixsharp.bin. However, this approach may not be practical. Additionally, using System.Diagnostics.Debugger.Launch() to debug operations is not feasible in Wixsharp.

A more efficient way is to use Debug.Assert(), which will throw an assertion if the condition is not met. You can prompt the debugger to start by triggering an assertion during a custom action.

Another approach is to wrap the important statements in #if DEBUG #endif preprocessor directives. This ensures that specific code is only executed when building in debug mode. Within these instructions, you can use System.Diagnostics.Debugger.Launch() to enter the debugger.

The following is an example of a custom action with debugging capabilities:

[CustomAction]
public static ActionResult CustomAction(Session session)
{
    #if DEBUG
        System.Diagnostics.Debugger.Launch();
    #endif

    MessageBox.Show("Hello World!" + session[IISSessions.AppPoolName], "外部托管CA");

    return ActionResult.Success;
}

After adding the debugging mechanism, build the project in debug mode and start the generated .msi file. When a custom action is triggered during installation, you will be prompted to open an instance of Visual Studio to debug the code.
