# Essential ASP.NET Core Snippets

This extension is optimized for developers who wants to develop ASP.NET Core 2/3 and Entity Framework Core 2/3.  These code snippets contains **C#**, **MSBuild**, **Razor** and **JSON** snippets.  So you can even write your own `appsettings.json` using my code snippets in a rocket speed.

This extension is still in progress.  [Let me know](https://github.com/doggy8088/netcore-snippets/issues) if you have any suggestion! Thanks!

## Features

* Support Minimal API for ASP.NET Core 6.0+
* Guess your project's namespace when creating a API Controller
* Generates `ConnectionStrings` in `appsettings.json` quickly
* Generates constructor method by default when creating a API Controller
* Including snippets that commonly used in `Program` class
* Including snippets that commonly used in `Startup` class
* Including Entity Framework Core common code patterns
* Generates `UseSpa()` snippet for ASP.NET Core 2.1+
