Basic Logical Operations with LINQ Expressions

How to implement basic logical operations (AND, OR, NOT, XOR) with LINQ expressions:

public static class ExpressionExtensions
	{
		public static Expression<Func<T, Boolean>> Or<T>(this Expression<Func<T, Boolean>> expr, Expression<Func<T, Boolean>> other)
		{
			InvocationExpression invokedExpr = Expression.Invoke(other, expr.Parameters.Cast<Expression>());
			return (Expression.Lambda<Func<T, Boolean>>(Expression.OrElse(expr.Body, invokedExpr), expr.Parameters));
		}

		public static Expression<Func<T, Boolean>> Xor<T>(this Expression<Func<T, Boolean>> expr, Expression<Func<T, Boolean>> other)
		{
			InvocationExpression invokedExpr = Expression.Invoke(other, expr.Parameters.Cast<Expression>());
			return (Expression.Lambda<Func<T, Boolean>>(Expression.ExclusiveOr(expr.Body, invokedExpr), expr.Parameters));
		}

		public static Expression<Func<T, Boolean>> Not<T>(this Expression<Func<T, Boolean>> expr)
		{
			return (Expression.Lambda<Func<T, Boolean>>(Expression.Not(expr.Body), expr.Parameters));
		}

		public static Expression<Func<T, Boolean>> And<T>(this Expression<Func<T, Boolean>> expr, Expression<Func<T, Boolean>> other)
		{
			InvocationExpression invokedExpr = Expression.Invoke(other, expr.Parameters.Cast<Expression>());
			return (Expression.Lambda<Func<T, Boolean>>(Expression.AndAlso(expr.Body, invokedExpr), expr.Parameters));
		}
