    Common Misconceptions in C# and .NET – Relying On Client Validation

    Application Engineering / By /

    Relying solely on client-side validation should be strictly avoided. It is not a reliable approach as skilled users can easily manipulate the client-side code to bypass the validation rules. Let’s examine example to illustrate this point. In our scenario, we have an ASP.net Razor-page application with login form. The form utilizes bind property attributes in …

    Common Misconceptions in C# and .NET: Understanding the Virtual and Override techniques in C#

    Application Engineering / By /

    Let us properly comprehend the concepts of polymorphism, C# virtual, and override techniques. In this example, we have an abstract class called Car, which includes a protected property named Speed. It also contains an abstract method called Accelerate, which increases the speed by ten whenever invoked. Additionally, there is a non-virtual implemented method called Stop, …
