How to Configure Visual Studio 2008 to Always Build the Startup Project

If you’re working with Visual Studio 2008 and have multiple projects within a solution, you may have encountered a frustrating issue: the startup project doesn’t always build as expected. In many setups, the startup project is responsible for organizing tasks and copying “plugin” projects using post-build events. However, after upgrading from VS 2005 to VS 2008, you might notice that your post-build event only fires when the startup project itself is modified. This leads to updated plugins not being integrated into your debugging session as they should be.

So, how can you ensure that your startup project is always rebuilt when you hit F5? Let’s explore a straightforward solution that leverages project dependencies.

Understanding the Problem

When you press F5 to start debugging a solution, Visual Studio determines which projects need to be rebuilt based on their last modified time. In VS 2008, it appears that this behavior may have changed, causing the startup project to be overlooked if it hasn’t been directly modified. This can lead to inefficiencies in your development process, particularly if you rely on post-build events for essential tasks.

Common Issues:

  • Plugins Not Updated: Changes made to plugin projects aren’t reflected in the debugging session.
  • Lack of Notification: Unlike in VS 2005, developers might feel blindsided by these changes, as there’s no clear indication of what’s being rebuilt.

The Solution: Add Project Dependencies

One effective workaround is to explicitly define dependencies between your startup project and the plugin projects. This means if any plugin project is modified, Visual Studio will know to rebuild the startup project accordingly. Here’s how you can set this up:

Steps to Set Project Dependencies

  1. Open Your Solution: Start Visual Studio 2008 and open the solution containing your startup and plugin projects.

  2. Access Project Properties:

    • Right-click on your solution in the Solution Explorer.
    • Select “Project Dependencies” from the context menu.

  3. Set Dependencies:

    • In the Project Dependencies dialog, select your startup project from the dropdown menu.
    • Below, you will see a list of projects in your solution.
    • Check the boxes for each plugin project that your startup project depends on.

  4. Confirm Changes: Once you’ve marked all necessary dependencies, click OK to apply these changes.

  5. Try Debugging Again: Run your solution by pressing F5. This time, whenever any of the marked plugin projects are modified, your startup project will automatically be rebuilt.

Benefits of This Approach

  • Simplicity: You no longer need to tinker with pre/post-build events, which can sometimes be complicated and error-prone.
  • Efficiency: Ensure that your latest plugin updates are always reflected in your debugging sessions without extra manual intervention.
  • Clarity: This method adds clarity to your project structure, making it easier for new team members to understand dependencies.

Conclusion

Using project dependencies is a practical and effective workaround for the challenges faced when upgrading to Visual Studio 2008. By ensuring that your startup project always builds when needed, you can streamline your development workflow, reduce frustration, and maintain a productive coding environment. Implementing these simple steps can significantly enhance your experience with Visual Studio.
