## Learning C# (Basics, Algorithms, Design Patterns, Data Structures, SOLID) > *"I am not afraid of a person who knows 10000 kicks.

Contains examples of both convinient and unconviniet examples - **Single Responsibility Principle** - `Do one thing, but do it best` - **Open-Closed Principle** - `App. should be open for extension, but closed for modification`. Usually, solved by pattern `Strategy` - **Liskov Substitution Principle** - `Proper abstractization, where all subclasses correctly implements methods from base class` - **Interface Segregation Principle** - `Clients should not be forced to depend upon interfaces that they do not use.` - **Dependency Inversion Principle** - `High-level modules should not depend on low-level modules. Both should depend on abstractions.` - `Abstractions should not depend on details. Details should depend on abstractions.` ## ASP NET MVC Core - https://github.com/kolosovpetro/Computer-Science/tree/develop/ASP%20NET%20MVC ## PostgreSQL and Entity Framework Core - Code First Approach (Migrations) - Database First Approach (Reverse engineering) ## ADO .NET - Introduction - Active record pattern - Data mapper pattern - Identity map pattern - Treadsafe singleton ## Information - **C# Keywords** - https://github.com/kolosovpetro/Computer-Science/tree/develop/Information/Keywords - **Mutable and Immutable types** - https://github.com/kolosovpetro/Computer-Science/tree/develop/Information/MutablesAndImmutables - **Notes** - https://github.com/kolosovpetro/Computer-Science/tree/develop/Information/Notes - **Nullable structs** - https://github.com/kolosovpetro/Computer-Science/tree/develop/Information/Nullables - **Git pull request guide** - https://github.com/kolosovpetro/Computer-Science/tree/develop/Information/GitPullRequest - **Terminology** - https://github.com/kolosovpetro/Computer-Science/tree/develop/Information/Terminology ## Computational Methods - Numerical Sys.
