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 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+
