Cyclomatic complexity is a code metric (integer value 1 or more) used to measure how complex a function/method is. It does not take into account lines of code but instead considers complexity to be the distinct paths through a function. Microsoft defines cyclomatic complexity as measuring the amount of decision...

LINQ (Language Integrated Query) is a powerful querying tool in .NET that allows you to perform complex queries directly in C#. The System.Linq.Expressions namespace is a part of LINQ that provides classes, interfaces, enumerations and structures to work with lambda expressions and expression trees. Lambda expressions are a way...

Understanding uow to use And and Or operators with Expression Trees As a C# developer, you may have come across scenarios where you need to build complex logical expressions dynamically based on user input or other dynamic factors.
