More instances of sqlserver and memory usage

Memory allocation concerning a value of value type?

27 May 2021 by OriginalGriff

Reference types are stored on the heap: value types may be stored on the stack. When you embed a value type in a reference type, it is a part of the class information - and since a reference type is always stored on the heap, the value type is...
