visual-studio intellisense csharp attributes C#

I'm dealing with I'm developing a C# application in Visual Studio 2022 and I've encountered an inconsistency with IntelliSense. I created a custom attribute and applied it to several classes, but IntelliSense only recognizes it for some of them. Here's the attribute definition: ```csharp [AttributeUsage(AttributeTargets.Class)] public class MyCustomAttribute : Attribute { public string Description { get; set; } public MyCustomAttribute(string description) { Description = description; } } ``` I applied this attribute to two classes: ```csharp [MyCustomAttribute("This is a test class")] public class TestClass1 { } [MyCustomAttribute("Another test class")] public class TestClass2 { } ``` However, when I try to use IntelliSense on `TestClass1`, I receive the expected suggestions, but for `TestClass2`, it fails to show the attribute in the IntelliSense popup. I've checked for typos and made sure both classes are in the same namespace. Additionally, I've tried cleaning the solution and rebuilding it, as well as restarting Visual Studio, but the scenario continues. I also verified that both classes are public and that the attribute is not being filtered out by any settings. Is there something specific about the way I defined or applied the attribute that could lead to this inconsistency? Any suggestions on how to get IntelliSense to recognize custom attributes consistently would be greatly appreciated!
