降级从.NET 4.0至3.5的应用程序 [英] Downgrade an application from .net 4.0 to 3.5

问题描述

我一直在开发在VS2010的应用程序，并编译它在.NET 4.0作为目标框架。集成库到我的应用程序后，我收到以下错误消息，当我试图编译：

I have been developing an application in VS2010 and compiling it for the .NET 4.0 as the target framework. After integrating a library into my application, I get the following error message when I try to compile:

混合模式组件构建针对运行时的版本V1.1.4322'，不能在4.0运行时无需附加配置信息加载。

Mixed mode assembly is built against version 'v1.1.4322' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.

.NET 3.5下的图书馆工作正常，但是当我改变我的目标框架到.NET 3.5，我得到了下面的错误我所有的.resx文件：

The library works fine under .NET 3.5, but when I change my target framework to .NET 3.5, I get the following error for all my .resx files:

1时出错对象引用不设置到对象的实例。

Error 1 Object reference not set to an instance of an object.

我试过CTRL-H版本= 4.0.0.0到版本= 3.5.0.0，但这似乎并没有工作。有什么我可以做其他的，创造一个新的应用程序？

I tried ctrl-h Version=4.0.0.0 to Version=3.5.0.0 but that doesn't seem to work. Is there anything I can do other that create a new application?

推荐答案

您应该能够使这项工作由配置设置中的app.config。

You should be able to make this work by configuration settings in app.Config.

就在 useLegacyV2RuntimeActivati​​onPolicy =真正的标记添加到您的 AppConfig的在启动部分。这使得.NET 4运行时处理旧的混合模式组件。

Just add the useLegacyV2RuntimeActivationPolicy="true" flag to your appConfig in the startup section. This causes the .NET 4 runtime to handle older mixed-mode assemblies.
