My WPF app is eating RAM like a crypto miner – help debug this leak 📉

[rmiss]

My C# project is sucking up resources like it's trying to brute force a private key and I have no idea why. It starts fine but climbs to multiple GBs of usage after just a few minutes. Any recommendations on profilers or common gotchas I should check first?

I feel you, been there with WPF apps too. Have you tried enabling garbage collection diagnostics in the Visual Studio debugger to see if it's a memory leak or just the CLR not releasing memory efficiently? Also, check if any of your UI elements are being re-created on every frame or something like that.

I've seen similar issues in the past that turned out to be caused by bindings that weren't being properly cleaned up, try adding some Dispose logic or looking into implementing the INotifyPropertyChanged interface correctly to see if that helps. Also, do you have a memory profiler running to give you an idea of what's consuming all the RAM?

Have you tried running your app under the memory profiler in Visual Studio to see where the leaks are happening? I'd also suggest enabling garbage collection logging to see if it's actually the app holding onto objects or if it's just not freeing up resources on GC. That usually gives me a good starting point for hunting down the issue.

Might be a good idea to turn on the WPF memory profiler in Visual Studio, it's pretty handy for tracking down these kind of issues. If it's a leak, you should be able to see where the memory is being allocated but not garbage collected.

dude I had a similar issue with my WPF app last year, turned out it was a rogue ObservableCollection that was causing the leak. Try using the CLR Profiler or dotMemory to see where the memory is being allocated, should give you a better idea of whats going on. Also check if you're properly disposing of any unmanaged resources or COM objects

Classic WPF struggle, mate. Check if you forgot to unsubscribe from event handlers or didn't freeze your bitmaps, because that'll nuke your RAM faster than a bad smart contract.

Dude, check your event handlers—if you're not unsubscribing, they'll hold onto objects forever. Grab a profiler like dotMemory to see exactly what the GC is ignoring.

Bro, check if you're actually unsubscribing from events when closing windows, that's the classic WPF trap. Run a memory profiler to see what's getting retained, otherwise that RAM usage is gonna moon.

Check if you forgot to unsubscribe from event handlers, that’s the classic WPF killer. Fire up a profiler like dotTrace and see which objects are refusing to get GC'd.

Bruh, unless you're actually mining in the background, you probably forgot to unsubscribe from event handlers. Check for static references holding onto your views—that’s the usual suspect.

Is FastAPI still relevant?

Lol at the mining analogy, glad you're aware it's a problem though. Have you tried using a profiling tool like Memory Profiler or Visual Studio's built-in tool to see which components are taking up all the memory? It might give you a clue on what's causing the leak.
