Microsoft .NET Framework（微软NET框架运行库）是Windows操作系统用于.NET Framework构建的应用程序所需的基础类型库组件。NET Framework是继Windows DNA之后的一个全新软件开发平台，微软.NET框架是以一种采用系统虚拟机运行的编程平台，以通用语言运行库为基础，支持多国语言的开发环境。NET框架的目的是便于开发人员更容易地建立Web应用程序和Web服务，使得Internet上的各应用程序之间，可以使用Web服务进行沟通。Microsoft .NET Framework是用于Windows的新托管代码编程模型。它将强大的功能与新技术结合起来，用于构建具有视觉上引人注目的用户体验的应用程序，实现跨技术边界的无缝通信，并且能支持各种业务流程。简单的来说就是电脑必备的运行环境。

很多第三方开发的软件有部分是基于Microsoft .NET Framework 框架来开发的，而这款软件如果是基于Microsoft .NET Framework v4.7.0 开发的话，那么你的电脑就必须安装有 Microsoft .NET Framework v4.7.0 或更高版的Microsoft .NET Framework 才能运行软件，反之Microsoft .NET Framework 低于软件开发环境，则该软件无法运行，这里亿破姐给大家带来的 Microsoft .NET Framework 官方正式版离线安装包提供，为什么要发布 Microsoft .NET Framework 官方正式版离线安装包，因为很多朋友百度搜索下载的 Microsoft .NET Framework 都是在一些下载站下载的捆绑下载器，这些下载站的捆绑下载器在下载应用的同时会偷偷在后台安装一大批流氓软件，捆绑主页等等行为，亿破姐提供的Microsoft .NET Framework 是官方的离线安装包，安全、可靠、无毒、无流氓、无广告、无捆绑。

Microsoft .NET Framework 是用于为 Web、Windows、Windows Phone、Windows Server 和 Microsoft Azure 构建应用的开发平台。 它包含公共语言运行时 (CLR) 和 .NET Framework 类库，其中包括各种功能和对许多行业标准的支持。
Microsoft .NET Framework  提供许多服务，包括内存管理、类型和内存安全、安全性、网络和应用程序部署。 它提供易于使用的数据结构和 API，将较低级别的 Windows 操作系统抽象化。 可在 .NET Framework 中使用不同编程语言，包括 C#、F# 和 Visual Basic
