Boxing is used to store value types in the garbage-collected heap. Boxing is an implicit conversion of a value type to the type object or to any interface type implemented by this value type. Boxing a value type allocates an object instance on the heap and copies the value into the new object Boxing Conversion explicit boxing is never required:… Read more →
Use as and is Operators for casting
The as operator is more efficient because it actually returns the cast value if the cast can be made successfully. The is operator returns only a Boolean value. It can therefore be used when we just want to determine an object’s type but do not have to actually cast it. Use the is operator to verify the type before performing a… Read more →

POCO,Code first,model first and database first discussion
POCO is a stand for plain old CLR object. This Class where we have control over its base type and implemented interfaces so it doesn’t have to use any API specific features – that works same in whole EF. Code first is still EF and it uses internally same infrastructure like EDMX so there is no difference. Difference is how… Read more →

Value Types and Reference Types Comparison
Intriguing Question Value Type Reference Type How is a variable represented? Value type variables are local copies. Reference type variables are pointing to the memory occupied by the allocated instance. What is the base type? Implicitly extends System.ValueType. Can derive from any other type (except System. ValueType), as long as that type is not “sealed” (more details on this in… Read more →
