可NET 2.0组件.NET 4.0下运行？ [英] Can .NET 2.0 assemblies run under .NET 4.0?

问题描述

我公司开发的.NET解决方案，包括几个组件，其中大部分是小帮手组件是针对.NET Framework 2.0版。其余的组件是MVC 3 Web应用程序，这必然针对4.0版本的.NET Framework。我的解决方案有除了.NET和MVC框架没有其他的外部依赖。

I have developed a .NET solution that consists of several assemblies, most of which are small helper assemblies that target version 2.0 of the .NET Framework. The remaining assemblies are MVC 3 Web applications, which must necessarily target version 4.0 of the .NET Framework. My solution has no other external dependencies besides the .NET and MVC Frameworks.

我的问题是：当我这个解决方案部署到客户，我必须部署.NET框架的两个版本，或者我可以只部署4.0版本？可NET 2.0组件.NET 4.0下运行？

My question is the following: When I deploy this solution to customers, do I have to deploy both versions of the .NET Framework, or can I just deploy version 4.0? Can .NET 2.0 assemblies run under .NET 4.0?
