 # Tell the debugger what to show using the DebuggerDisplay Attribute (C#, Visual Basic, F#, C++/CLI)
 
-The <xref:System.Diagnostics.DebuggerDisplayAttribute> controls how an object, property, or field is displayed in the debugger variable windows. This attribute can be applied to types (classes, structs, enums, delegates). If applied to a base type, the attribute also applies to a subclass.
+The <xref:System.Diagnostics.DebuggerDisplayAttribute> controls how an object, property, or field is displayed in the debugger variable windows. This attribute can be applied to types (classes, structs, enums, delegates), but is typically applied only to classes and structs. If applied to a base type, the attribute also applies to a subclass.
 
 The `DebuggerDisplay` attribute has a single argument, which is a string to be displayed in the value column for instances of the type. This string can contain braces (`{` and `}`). Text within a pair of braces is evaluated as a field, property or method.
