Implementation of SimpleExpressionVisitor that does the replacement * MethodExpanderAttribute * MemberXXXExpression static field * ExpressionExtensions.Expand method It also simplifies and skip evaluating short circuited subexpresions Evaluates constant subexpressions
Inheritance: System.Linq.Expressions.ExpressionVisitor
