Visual Studio 2022 Not Releasing Memory After Async Method Execution in WinForms Application
I'm converting an old project and I'm wondering if anyone has experience with I'm learning this framework and Quick question that's been bugging me - I'm currently facing a memory leak issue in my WinForms application developed with .NET 6.0. After executing an async method, I notice that the memory usage spikes significantly and doesn't seem to decrease even after the method completes. The method performs some database operations and updates the UI based on the results. Here's a simplified version of what I'm doing: ```csharp private async void btnFetchData_Click(object sender, EventArgs e) { var data = await FetchDataAsync(); UpdateUI(data); } private async Task<List<MyData>> FetchDataAsync() { using (var connection = new SqlConnection(connectionString)) { await connection.OpenAsync(); var command = new SqlCommand("SELECT * FROM MyTable", connection); var reader = await command.ExecuteReaderAsync(); var result = new List<MyData>(); while (await reader.ReadAsync()) { result.Add(new MyData { Id = reader.GetInt32(0), Name = reader.GetString(1) }); } return result; } } private void UpdateUI(List<MyData> data) { myListBox.DataSource = data; } ``` I've tried forcing garbage collection using `GC.Collect()` after the method runs, but it didn't help. I've also checked for any lingering references to the data, and I don't see any obvious leaks. Additionally, I've verified that all disposable objects are being disposed of correctly. I'm running this on Visual Studio 2022 with .NET 6.0, and my application sometimes consumes up to 1.5 GB of RAM after performing multiple fetches, which is concerning. I would appreciate any insights on what might be causing this memory retention or if there are any best practices I should be following in async programming to prevent such issues. My development environment is Windows. What am I doing wrong? I'm on Windows 11 using the latest version of Csharp. I appreciate any insights! This is happening in both development and production on macOS. This is my first time working with Csharp stable. I'd be grateful for any help.
