答案 0 :(得分：3)
有些特殊规则适用于像您这样的COM服务器。 .NET 4中的CLR支持CLR的进程内并行版本控制，允许进程承载多个版本的CLR。这对于COM服务器尤其重要，它解决了以前无法可靠地创建托管shell扩展的CLR版本注入问题。 CLR版本2及更早版本仅在一个进程中支持一个版本的CLR。由于副作用，无论COM服务器首先加载CLR，都将无法在以后加载需要更高版本CLR的COM服务器。如果第一台COM服务器加载了1.0或1.1版本的CLR，则特别糟糕。
如果您不想以.NET 4为目标，那么您将不得不要求用户安装.NET 3.5 SP1，以便可以注册服务器。您还必须为客户端程序提供app.exe.config文件，以告知CLR您知道您的COM服务器是为早期版本的CLR构建的，并且可以使用版本4 CLR运行它。这样可以防止使用版本2 CLR。 .config文件应如下所示：
<configuration>
<startup useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime version="v4"/>
<supportedRuntime version="v2.0.50727"/>
</startup>
</configuration>
显然，对于只有4的用户，你可以将.NET 4作为目标。请记住，如果客户端程序完全是原生的，你实际上可能更喜欢加载版本2 CLR，这可能就是你的版本了用你的代码测试了你的代码。版本4具有高度兼容性，但它确实针对您的代码无意中可能依赖的错误修复了许多错误。
