简单介绍.net core 如何实现跨平台和静态编译（写好的程序无法再被直接反编译源码）的桌面应用程序

我之前一直都被研究如何静态编译，因为源码直接被人反编译真的是非常烦恼的事情，试过很多方式，也换过很多语言，直到我发现了这款基于.net core的开源的跨平台UI库

Ui库官方地址：Avalonia UI

接下来我为大家带来简单的使用教程，如果要使用此功能的话，需要有一定的wpf开发基础

1、首先我们需要安装它的vs扩展Avalonia，如图所示

2、安装好后重新打开VS。选择创建新项目

 

3、简单了解创建的项目文件 

 4、然后我们就可以进行跟wpf一样的开发了。

5、重点呢，就是编译和生成这块了。发布这块跟.net core 跨平台发布是基本一致的，选择所需要的平台，进行编译就行了。

 这样呢，基本上的跨平台程序就做好了的。

但是呢，我们还有静态编译的发布方式，就是需要在项目中引用Microsoft.DotNet.ILCompiler

我们可以在包管理器中进行安装。这部分如果没有静态编译的需求的话，就不需要了。因为这部分非常的麻烦，虽然引入了这款aot编译的dll之后，正常生成就行了，但是如果我们使用到了别的第三方类库，那我们就得添加第三方库的rd.xml代码

 像Avalonia这款第三方库，我们需要添加如下rd.xml才可以进行静态编译。

在项目根目录中添加这个rd.xml，然后进行正常的发布编译，就行了。这样你发布的代码就是AOT静态编译了
