Getting 'The type initializer for 'MyNamespace.MyClass' threw an handling' in .NET 6 with Static Constructor
I'm relatively new to this, so bear with me. I'm learning this framework and I'm having a hard time understanding I've searched everywhere and can't find a clear answer... I'm experiencing a frustrating scenario with a static constructor in my C# application running on .NET 6. The behavior message states: `System.TypeInitializationException: The type initializer for 'MyNamespace.MyClass' threw an exception.` This occurs when I'm trying to access a static property from another class. Here's a simplified version of my code: ```csharp namespace MyNamespace { public class MyClass { private static readonly string _configValue; static MyClass() { try { _configValue = ConfigurationManager.AppSettings["MySetting"]; // Simulating a potential scenario if (string.IsNullOrEmpty(_configValue)) { throw new InvalidOperationException("Configuration value is missing."); } } catch (Exception ex) { // Log the exception Console.WriteLine($"behavior while initializing MyClass: {ex.Message}"); throw; } } public static string GetConfigValue() => _configValue; } } namespace OtherNamespace { public class OtherClass { public void UseMyClass() { try { string configValue = MyNamespace.MyClass.GetConfigValue(); Console.WriteLine(configValue); } catch (TypeInitializationException ex) { Console.WriteLine($"Caught exception: {ex.InnerException?.Message}"); } } } } ``` When I run the `UseMyClass` method, I catch the `TypeInitializationException`, but the inner exception doesn't provide much insight beyond the fact that the static constructor failed. I've confirmed that my app settings file has the `MySetting` key defined, so I don't understand why `_configValue` would end up being null. I've also looked into potential issues with the configuration loading order but couldn't find anything amiss. I've tried debugging the static constructor and ensured that the app settings are accessible at runtime, yet the scenario continues. Any thoughts on what could be causing this or how I might diagnose it further? My development environment is Ubuntu. Any ideas what could be causing this? My development environment is Debian. Any examples would be super helpful. For reference, this is a production service. What would be the recommended way to handle this? I'm working in a CentOS environment. What am I doing wrong?
