c# memory-leak disposable C#

I'm deploying to production and I've been banging my head against this for hours... I've searched everywhere and can't find a clear answer. I tried several approaches but none seem to work. I'm currently facing a memory leak issue in my C# 10 application when utilizing a custom class that implements `IDisposable`. The class is responsible for processing data from a large collection, and I'm using a `MemoryStream` inside it. After executing several processing cycles, I notice that the memory usage continues to grow despite the expected disposal of resources. Here's the relevant code snippet showcasing my custom class implementation: ```csharp public class DataProcessor : IDisposable { private MemoryStream _memoryStream; private bool _disposed = false; public DataProcessor() { _memoryStream = new MemoryStream(); } public void ProcessData(byte[] data) { if (_disposed) throw new ObjectDisposedException(nameof(DataProcessor)); // Simulating data processing _memoryStream.Write(data, 0, data.Length); // Additional processing logic... } public void Dispose() { Dispose(true); GC.SuppressFinalize(this); } protected virtual void Dispose(bool disposing) { if (!_disposed) { if (disposing) { _memoryStream?.Dispose(); // Dispose managed resources } // Free unmanaged resources if any _disposed = true; } } } ``` I'm instantiating this class inside a loop where I process multiple datasets. After each dataset is processed, I call `Dispose()` on the `DataProcessor` instance. However, when I monitor the application's memory usage, I can see that it continues to climb. Here’s how I’m using the class: ```csharp for (int i = 0; i < datasetCount; i++) { using (var processor = new DataProcessor()) { processor.ProcessData(myDataArray[i]); } } ``` I've tried ensuring that every reference to the `DataProcessor` is disposed of correctly, and I've also enabled the `GC` logging to see if there’s something being held in memory. Unfortunately, the problem persists. Could there be something I'm overlooking with the disposal pattern or perhaps something related to how `MemoryStream` manages its buffers? Any insights or suggestions on diagnosing this memory leak would be greatly appreciated. Thanks in advance! Is there a better approach? My development environment is Windows. What am I doing wrong? My development environment is Windows 10. Thanks, I really appreciate it!
