 A *default_value_expression* is a constant expression ([§12.20](expressions.md#1220-constant-expressions)) if *type* is a reference type or a type parameter that is known to be a reference type ([§9.2](types.md#92-reference-types)). In addition, a *default_value_expression* is a constant expression if the type is one of the following value types: `sbyte`, `byte`, `short`, `ushort`, `int`, `uint`, `long`, `ulong`, `char`, `float`, `double`, `decimal`, `bool,` or any enumeration type.

 An *anonymous_method_expression* is one of two ways of defining an anonymous function. These are further described in [§12.16](expressions.md#1216-anonymous-function-expressions).
