.NET Support: It’s Not as Boring as You Think (But It’s Still Important)

Reading about software support lifecycles isn't exactly a thrill ride. It's kind of like reading the instruction manual for your dishwasher – necessary, but not exactly riveting. However, unlike ignoring your dishwasher manual (which might just lead to some dirty dishes), ignoring .NET support lifecycles can lead to a whole lot of pain for you and your applications. If you're a .NET developer or IT professional, understanding the support lifecycle for your .NET and .NET Core versions is really important. It directly impacts your upgrade planning, security and the health of your applications. Let's break down what you need to know:

The Good News: .NET Support is Pretty Straightforward

Microsoft has actually made this whole thing surprisingly painless. You have two main options for .NET releases through regular patches and updates. The kind of support and its duration depend on whether you're using a Long Term Support (LTS) or Standard Term Support (STS) release.

• Long Term Support (LTS): The “slow and steady” version. It gets updates and patches for a glorious three years. Perfect for those who like stability and don’t need the absolute cutting-edge features. These are ideal for stable, long-running applications.?
• Standard Term Support (STS): The “live life on the edge” version. It gets updates for 18 months, but you get access to all the latest and greatest features faster. These are great for keeping up with the latest features and innovations.

Which one is right for you? Well, that depends on your project and your risk tolerance.?

• Are you building a nuclear power plant control system? Maybe stick with LTS.?
• Are you building a super cool, experimental AI-powered chat app? STS might be more your speed.?

The quality of both release types is the same, so the choice really comes down to your specific project needs.

The Current Landscape of .NET Support

Important Note: .NET 5 and various .NET Core versions are no longer supported. If you're using these, upgrading should be a priority to ensure the security and functionality of your applications.

The Not-So-Good News: Updates Are Still Mandatory

Here’s the deal: to keep getting those sweet, sweet security patches and bug fixes, you must keep your .NET installations up-to-date. It’s like brushing your teeth — a little annoying, but it saves you from a lot of pain in the long run. For example:

• LTS: You need the latest patch update for your specific 6.0.x version.
• STS: You need the latest patch update for your specific 7.0.x version.

The Ugly Truth: Unsupported .NET is a Recipe for Disaster

Remember that time you thought you could skip patching your operating system and then your computer got turned into a cryptocurrency mining zombie? Yeah, running unsupported .NET is kind of like that. You’re basically leaving your application open to all sorts of nasty vulnerabilities.

The Silver Lining: Microsoft Makes it Easy to Stay Updated

Microsoft releases a new major .NET version every November, alternating between LTS and STS. They’re basically handing you a roadmap to avoid the .NET apocalypse. Just follow the schedule, keep those updates rolling and you’ll be golden. .NET updates are cumulative and include:

• New features (occasionally)
• Security fixes
• Non-security fixes

These updates are usually released on Microsoft's “Patch Tuesday” (the second Tuesday of each month).

The Bottom Line:

• Know Your .NET: Figure out if you’re running LTS or STS.
• Patch it Up: Keep those updates coming.
• Plan Ahead: Mark your calendar for the next .NET release.
• Ditch the Zombies: If you're running an unsupported version, upgrade ASAP.

By following these steps, you can avoid a whole lot of headaches and ensure your .NET applications are running smoothly (and securely) for years to come.?
