.NET 9 Upgrade: Future-Proof Your Business with Superior Performance and Security

Upgrading your software platform is about more than just adopting the latest technology—it’s a strategic business decision that drives efficiency, security, and competitive advantage. In today’s fast-paced market, sticking with outdated frameworks can be as costly as it is risky. Let’s explore the journey towards .NET 9 and understand how this upgrade can bring tangible benefits to your business.

A Story of Transformation

Imagine a development manager in Sydney discussing his team’s hesitation over upgrading from a legacy framework. His concern wasn’t unfounded: technical debt and the fear of disruption are real. Yet, by choosing to upgrade, his organisation not only enhanced its application performance but also reaped significant cost savings and opened the door to modern AI capabilities. This is the kind of transformative story that many businesses experience when they invest in modernisation.

Why Upgrade? Business and Technical Benefits

Enhanced Performance and Cost Savings

.NET 9 delivers impressive performance gains that can directly impact your bottom line:

• Faster Startups: Applications now launch approximately 15% quicker, meaning your users can get to work without delay.
• Improved Resource Efficiency: With a reduction in memory usage by 8–12% and faster JSON processing (up to 35% improvement), you can expect lower cloud costs and a smoother user experience.
• Optimised Web Requests: Kestrel’s improvements translate into web requests being processed 20% faster with 25% less latency.

These technical enhancements often lead to real business savings. For instance, one client reported nearly a 20% drop in their Azure spend after moving to .NET 9—a clear example of technology investments paying for themselves.

Unlocking Advanced AI Capabilities

In a world where data drives decision-making, .NET 9’s native support for AI can be a game changer:

• Built-In AI Support: Leverage large language models directly within your applications.
• Efficient Data Processing: New tensor types and vector storage make it simpler to integrate AI without complex workarounds.

A real-world example saw a team cut their AI integration code by 60%, which not only streamlined their development process but also accelerated their time to market.

Mitigating Migration Challenges

Of course, every upgrade comes with its challenges. Here’s how to navigate some common issues:

NuGet Dependency Resolution

A new NuGet dependency resolver might download unexpected packages—this can slow your build process. The simple fix is to use the RestoreUseLegacyDependencyResolver flag in your MSBuild configuration. Although this may temporarily reduce restore speed, it allows you to manage your dependencies carefully. For further guidance, check out SSW’s Rules to Better Nuget rule.

Removing Legacy Technologies

.NET 9 has bid farewell to the insecure BinaryFormatter. Transitioning to modern serializers like System.Text.Json not only improves performance but also enhances security. While this might seem daunting at first, many businesses find that the upgrade paves the way for cleaner, more maintainable code. To see how best to approach this change, read SSW’s modernisation guidance.

Fine-Tuning API Changes

Some adjustments—such as switching to an integer overload for TimeSpan.FromSeconds—ensure greater precision in time-sensitive code. These small changes help avoid bugs and maintain the integrity of your applications.

A Structured Approach to Migration

A successful migration is built on careful planning and execution. Consider these steps:

1. Begin with a Proof of Concept: Test the new environment on a non-critical application. This helps your team familiarise itself with the new framework features without risking business continuity.
2. Audit Your Dependencies: Use robust tools to identify and update outdated NuGet packages. For a comprehensive approach, refer to SSW’s Rules to Better Nuget and related content on updating your packages.
3. Benchmark and Validate: Set up performance tests to measure improvements before and after migration. This data not only builds confidence internally but also provides a clear picture of ROI.
4. Leverage Expert Consultation: Sometimes, a guided approach makes all the difference. SSW offers a one-hour free call consultation to help you map out the best upgrade strategy tailored to your business needs. Book a FREE Initial Meeting with SSW today.
