More outstanding achievement and well-being have all been associated with having a growth mindset, a mentality that one's talents can be developed through work and learning. As it requires confronting rooted ideas and thought habits, shifting one's mentality can be time- and effort-consuming. But you can start today and improve yourself in every way. The future still needs to be written. It's up to you to write it. Anything is possible! I wish you a great week ahead 👋. #technology #softwareengineering #techworldwithmilan #careers #personaldevelopment

How do you migrate from Monolith to Microservices architecture? Bad way: - Start building a monolith without a plan - End up writing a tightly coupled mess - Realize you have a problem - Save face by moving to microservices - End up with a distributed monolith 💩 Smart way: - Start building a Modular Monolith - Define module boundaries well - Make modules loosely coupled - Isolate database dependencies - Migrate to Microservices by extracting modules Modular design >>> Tightly coupled mess

It's where you define your entities and the most important business logic. So, I want to share a situation I ran into recently. I was looking at a project I built many years ago. The folder structure in the Domain layer bothered me. I was focusing on technical concerns instead of features. The symptoms of this are folders with names like: - Entities - Enumerations - Exceptions - Repositories - ValueObjects I'm sure you've done (or seen) this at some point. What's the problem with grouping by type? This folder structure doesn't tell you anything about the Domain. So what did I do? I reorganized the folders to group them by "feature". When you do this, domain concepts start appearing in the folder structure. The benefits of this approach are: - Better cohesion - High coupling for a single feature - Low coupling between unrelated features If you ever heard of Vertical Slice Architecture, it's a similar concept.

How to implement Singleton class lazy loaded in C#? Create a sealed class, with a private constructor and with a public instance that returns lazily instantiated members. 𝗪𝗵𝘆 𝘀𝗲𝗮𝗹𝗲𝗱 - We want only one instance of our class - No class should be able to inherit from this 𝗪𝗵𝘆 𝗰𝗼𝗻𝘀𝘁𝗿𝘂𝗰𝘁𝗼𝗿 𝗶𝘀 𝗽𝗿𝗶𝘃𝗮𝘁𝗲 - To avoid multiple instance creation 𝗪𝗵𝘆 𝗹𝗮𝘇𝘆 - Lazy is thread-safe - It can improve performance - Delays instantiation of class until needed 𝗔𝗿𝗲 𝘆𝗼𝘂 𝘀𝘂𝗿𝗲 𝗼𝗻𝗲 𝗶𝗻𝘀𝘁𝗮𝗻𝗰𝗲 𝗶𝘀 𝗯𝗲𝗶𝗻𝗴 𝗰𝗿𝗲𝗮𝘁𝗲𝗱 - With sealed no chance of being inherited - No direct instantiation constructor is private - Read-only ensures that the lazy property is initialized once 𝗛𝗼𝘄 𝘀𝗼 Either during the static constructor or before the class is first accessed, and is never modified again. But only a read-only keyword does not guarantee it is right! That's why we have made the property of only getter type you would note it does not have a setter in it. 𝗛𝗼𝘄 𝗶𝘀 𝘁𝗵𝗲 𝘀𝗲𝗰𝗼𝗻𝗱 𝗶𝗺𝗽𝗹𝗲𝗺𝗲𝗻𝘁𝗮𝘁𝗶𝗼𝗻 𝗱𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝘁 𝘁𝗵𝗮𝗻 𝗳𝗶𝗿𝘀𝘁 - Gets rid of the lock; too costly. - Lazy<T> class will make sure that only it would be created when it is needed and one time 𝗕𝘂𝘁 𝘁𝗵𝗶𝘀 𝗶𝘀 𝘀𝘁𝗶𝗹𝗹 𝗻𝗼𝘁 𝗯𝗲𝘀𝘁 Because the inversion of control is more appropriate compared to the instantiation of class through properties 📌 𝗣.𝗦:- Join my weekly .NET Newsletter with 𝟲𝟬𝟬𝟬 : lnkd.in/dNHxJGRG.
