Optimistic Locking vs Pessimistic Locking in .NET
Since the invention of database systems, they have become the primary source of truth for almost every web application's data. As user demands grow, applications scale, and so does the concurrency within the system. Ensuring data integrity and consistency along with...
Early Binding and Late Binding in C#
In C#, method binding refers to associating a method call with the method's code definition. When we invoke a method, the program determines which specific method to execute. This process, known as "binding," can occur at two different times: during compile-time...
