加载针对性的.NET 4.5在.NET 4.0应用程序域的组件 [英] Loading an assembly targetted for .NET 4.5 on a .NET 4.0 app domain

问题描述

假设系统具有.NET 4.0和.NET 4.5安装。

Assuming the system has .NET 4.0 and .NET 4.5 installed.

是否有可能加载和与.NET 4.5组件从书面打靶.NET 4.0的装配工作？

Is it possible to load and work with a .NET 4.5 assembly from an assembly written targetting .NET 4.0 ?

简单的说，我可以打电话的Assembly.Load从.NET 4.0 code加载.NET 4.5打靶组装？

Simply put, can I call Assembly.Load from .NET 4.0 code to load a .NET 4.5 targetting assembly ?

推荐答案

假设一个系统，.NET 4.0和.NET 4.5：

Assuming a system as .NET 4.0 and .NET 4.5:

4.5就地过度的顶部安装在4.0之上，在GAC;一旦你已经安装了4.5，4.0次操作，4.5组件

4.5 is an in-place over-the-top install on top of 4.0, in the GAC; once you have installed 4.5, 4.0 runs with the 4.5 assemblies

然后调用的Assembly.Load从.NET code目标4.0（由4.0编译器编译），将在实际使用4.5框架实现运行，因此我看不出有任何理由为什么它无法加载4.5组装。

Then calling Assembly.Load from a .NET code targeting 4.0 (compiled by a 4.0 compiler), will actually run in using the 4.5 framework implementation, so I don't see any reason why it couldn't load a 4.5 assembly.

margravell指出，当您试图在仅安装4.0的系统上运行.NET 4.5编译code会出现问题，因为收益率回报的执行/突破迭代器会导致丢失的方法引用。但是，这不应该影响到你。

margravell notes that problems occur when you try to run .NET 4.5 compiled code on a system with only 4.0 installed, as the implementation of the yield return/break iterators causes a missing method reference. But this shouldn't affect you.
