The Challenge of Distributing .NET 3.5: Alternatives to the 200 MB Redistributable Package

As a developer, one of the most significant obstacles you may encounter is ensuring that your application runs smoothly on a user’s machine. This becomes particularly challenging when building applications that utilize the .NET framework, especially the .NET 3.5. A common issue arises when the required redistributable package is an enormous 200 MB. For applications designed for a seamless user experience, requiring such a large download can turn users away, negating your efforts to create a “quick and painless” installation process.

Understanding the Problem

The Implications of a Large Download

When distributing applications relying on .NET 3.5, developers must consider:

  • User Experience: Users typically expect software that is easy and quick to install. A lengthy download time can lead to frustrations and potential drop-offs.
  • Target Audience: Many users do not have the latest versions of the .NET framework, thus requiring the full redistributable package. This increases installation time and decreases satisfaction.
  • Installation Time: Your goal is to minimize the installation time to under two minutes, which can be hard to achieve with a large 200 MB download.

Solutions to the 200 MB Dilemma

Fortunately, developers are not without options. While the full 200 MB redistributable package may be daunting, several alternatives can help streamline the installation process.

1. Utilize the .NET 3.5 SP1 Bootstrapper

Instead of relying on the full redistributable package, consider using the .NET 3.5 SP1 Bootstrapper. This lightweight installation package comes in at around:

  • File Size: Approximately 3 MB
  • Functionality: The Bootstrapper will only fetch the necessary components required for installation, significantly reducing the overall package size and installation time.

2. Explore the Smallest .NET Approach

To further enhance your application’s performance, Scott Hanselman has provided a new resource at SmallestDotNet.com. This tool helps you identify the essential components needed for your application, allowing you to minimize the download size as much as possible.

3. Consult Additional Resources

Conclusion

Distributing applications that depend on .NET 3.5 can be challenging, particularly with its large redistributable package. However, by utilizing tools like the .NET 3.5 SP1 Bootstrapper and leveraging resources such as SmallestDotNet.com, you can significantly improve installation times and user satisfaction.

By being proactive in seeking these alternatives, you are ensuring that your application remains user-friendly and accessible to a wider audience.
