Here's Why Maybe Monad is Your New Best Friend2024-04-02T23:59:59+02:00 2024-04-02T23:59:59+02:00 https://blog.zsmahi.com/posts/null-reference-exceptions-csharp-maybe-monad/ zsmahi Introduction Greetings, fellow developers! In the realm of software development, null reference exceptions have notoriously been dubbed the “billion-dollar mistake”. This pervasive issue spans across programming languages, leading to runtime errors that not only are challenging to debug but also to resolve. Specifically, in C#, numerous strategies have been proposed to tackle this problem. Am...

In the realm of .NET development, Entity Framework Core (EF Core) stands as a beacon of efficiency and elegance, providing a bridge between the object-oriented world of .NET entities and the relational universe of databases. This post embarks on an in-depth exploration of how EF Core navigates the complex process of mapping entities to database objects, ... EP04- Improving Asynchronous Programming in C# with Fluent API Style Task Chaining2023-07-29T21:00:00+02:00 2023-07-29T21:00:00+02:00 https://blog.zsmahi.com/posts/chainig-tasks-clean-way/ zsmahi Introduction Hello, fellow developers! Modern C# development heavily leans on asynchronous programming models, especially when dealing with I/O operations or services that may cause your application to pause or block while waiting for the response. Using the Task-based asynchronous pattern (TAP) with async and await keywords has become a standard way to perform such operations. However, when...
