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. In such cases, building expressions statically can become tedious and error-prone. In...

Maximizing performance in asynchronous programming Task and Task<TResult> The Task and Task<TResult> types were introduced in .NET 4.0 as part of the Task Parallel Library (TPL) in 2010, which provided a new model for writing multithreaded and asynchronous code.
