# 🌈C#/.NET/.NET Core学习、工作、面试指南
> 让现在的自己不再迷茫✨✨✨。
## 📚DotNetGuide简介
在当前技术生态中，关于Java、前端、Android、Golang...等相关技术的学习资料、工作心得、面试指南随处可见，但是咱们C#/.NET的相关学习资料、工作心得、面试指南却显得零散而稀缺。**我在QQ技术群、微信技术群、知乎里面经常会看到这样的提问：有没有好的C#/.NET相关的学习书籍、视频教程、项目框架和常见面试题推荐的？** 并不是没有人写，而是因为网上的资料和文章太零散了，缺少一个这方面汇总的知识库。作为一名.NET开发者而言当然是不想让这种现象普遍存在的，创建DotNetGuide知识库的初衷就是为了记录、收集和总结优质的.NET相关学习资料（学习路线、视频、文章、书籍、项目、框架...等）、开发实战教程、编程技巧练习、开发必备工具、技术前沿周刊、常见面试题、面试须知、简历模板、人才招聘、以及自己在学习和工作中的一些微薄见解，希望可以帮助到那些想要入门学习.NET或者正在使用.NET的同学。一个人的力量是十分有限的，由衷的欢迎大家可以在Issues中投稿或者直接提交PR一起完善我们的C#/.NET/.NET Core学习、工作、面试指南知识库🤞。
## 👨👩👦DotNetGuide技术社区
- DotNetGuide技术社区是一个面向.NET开发者的开源技术社区，旨在为开发者们提供全面的C#/.NET/.NET Core相关学习资料、技术分享和咨询、项目框架推荐、求职和招聘资讯、以及解决问题的平台。

## 🧱设计模式
> 设计模式（Design Pattern） 是一套被反复使用、多数人知晓的、经过分类编目的、代码设计经验的总结，使用设计模式是为了可重用代码、让代码更容易被他人理解并且保证代码可靠性。
> 面向对象结合设计模式，才能真正体会到程序变得可维护、可复用、可扩展、灵活性好。设计模式对于程序员而言并不陌生，每个程序员在编程时都会或多或少地接触到设计模式。无论是在大型程序的架构中，亦或是在源码的学习中，设计模式都扮演着非常重要的角色。
