C# Task.Run() causing advanced patterns in async operations with deadlocks

async-await deadlock task dotnet5 csharp

I've spent hours debugging this and I'm wondering if anyone has experience with I'm learning this framework and I've searched everywhere and can't find a clear answer... I'm experiencing a deadlock situation in my C# application when using `Task.Run()` to execute an asynchronous method. My application is targeting .NET 5, and I'm trying to invoke an async method inside a synchronous context. Here's a simplified version of what I'm trying to do: ```csharp public class DataFetcher { public void FetchData() { var result = Task.Run(() => GetDataAsync()).Result; Console.WriteLine(result); } private async Task<string> GetDataAsync() { await Task.Delay(1000); // Simulating a network call return "Data fetched"; } } ``` When I call `FetchData()`, it hangs indefinitely at `Task.Run()`. I've tried wrapping the call in `ConfigureAwait(false)` but that didn’t seem to help. I also tested by using `.GetAwaiter().GetResult()` instead of `.Result`, but the scenario continues. I’ve read that mixing async and synchronous code can lead to deadlocks, especially when the synchronization context is captured, but I’m not sure how to properly refactor this. I want to maintain the synchronous method while fetching data asynchronously. Is there a recommended way to handle this without running into deadlocks? Any advice would be appreciated! Is there a better approach? Has anyone dealt with something similar? I'm working with Csharp in a Docker container on Windows 10. The stack includes Csharp and several other technologies. Cheers for any assistance!
