<p>在 <code>.NET6/C#10</code> 之后，微软新增了 <code>GlobalUsings</code> 机制，可以在项目的根目录下创建一个 <code>GlobalUsings.cs</code> 文件，把常用的 <code>using</code> 放置其中。</p>
<p>这样 <code>GlobalUsings.cs</code> 所在的项目 <code>.cs</code> 文件就无需重复 <code>using</code> 了，大大的提高开发效率，也让代码变的更加简洁。</p>
<h2 class="anchor anchorWithHideOnScrollNavbar_WYt5" id="2122-必要配置">2.12.2 必要配置<a href="#2122-必要配置" class="hash-link" aria-label="Direct link to 2.12.2 必要配置" title="Direct link to 2.12.2 必要配置">​</a></h2>
<p><strong>启用 <code>GlobalUsings</code> 机制需要以下两个步骤：</strong></p>
<ol>
<li>在你需要全局 <code>using</code> 的项目层根目录创建 <code>GlobalUsings.cs</code> 文件，如果多个项目层需要，则每个层都应该有一个 <code>GlobalUsings.cs</code></li>
<li>编辑项目的 <code>.csproj</code> 文件，添加 <code>&lt;ImplicitUsings&gt;enable&lt;/ImplicitUsings&gt;</code>，注意是在 <code>&lt;PropertyGroup&gt;</code> 中添加，通常和 <code>&lt;TargetFramework&gt;</code> 同父同级</li>
</ol>

<p>配置之后，现在就可以把常用的 <code>using</code> 放到 <code>GlobalUsings.cs</code> 中了，写法如下：</p>

<p><strong>也就是以上的 <code>using</code> 无需写在你创建的 <code>GlobalUsings.cs</code> 中了，微软会在编译时自动合并。</strong></p>

<p>默认情况下，<code>.NET5</code> 采用 <code>C# 9.0</code> 编译，而 <code>GlobalUsing</code> 是从 <code>C# 10.0</code> 开始，这时候只需要编辑项目的 <code>.csproj</code> 并添加 <code>&lt;LangVersion&gt;10.0&lt;/LangVersion&gt;</code> 即可：</p>
