Your .NET app’s biggest performance issue isn’t CPU — it’s memory misuse.

Most .NET devs think “GC will handle it.”

That’s the biggest mistake I see in production apps.

Memory leaks and high GC pressure aren’t GC bugs — they’re developer misunderstandings.

Your app runs fine… until the memory keeps rising and never drops.

I saw this in an ASP.NET Core app where GC.Collect() was used manually by Junior Dev.

Performance dropped, CPU spiked, and memory never truly freed.

.NET’s Garbage Collector already segments memory into 3 generations — optimize your code, not the GC.

Use tools like dotnet-trace, Visual Studio Profiler, or Application Insights to analyze leaks instead.

How often do you analyze your app’s memory usage before deploying to Azure? Ever caught a leak that surprised you?
