我刚刚将我的C#winforms应用程序从dotnet 2.0(VS2010)升级到dotnet 4.5(VS2015)。我在尝试运行时遇到此错误:
混合模式程序集是针对版本'v2.0.50727'构建的 运行时无法在没有附加的情况下加载到4.0运行时 构造
经过大量的研究,我理解它,因为我的dotnet 4.5应用引用了使用dotnet 2.0(或者我认为是3.0或3.5)构建的代码。解决方案(根据我所读到的)是在app.config文件中添加一些文本。但无论我添加什么(每次关闭应用程序),它都无法正常工作。
到目前为止,我已经尝试过(没有特别的顺序):
<startup useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5"/></startup>
和
<startup useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime version="v4.5" sku=".NETFramework,Version=v4.5"/>
<requiredRuntime version="v4.5.50709" />
</startup>
和
<startup useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
<requiredRuntime version="v4.0.20506" />
</startup>
和
<startup useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
<supportedRuntime version="v2.0.50727"></supportedRuntime>
</startup>
和
<startup useLegacyV2RuntimeActivationPolicy="true" />
我的事情已经不多了。
我不确定这是否相关,但当我将鼠标放在某些区域时,我的App.config文件会发出警告,给我一条消息:
命名空间'urn:schemas-microsoft-com:asm.v1'的导入模式 没有解决。
我在另一篇帖子中提到了这一点,但有人说这应该不是问题。以下快速截图: Mouseover message
非常感谢任何协助。
我当前的App.config如下所示:

答案 0 :(得分:-1)
问题最终成为我正在使用的一个特定的dll(dotnet v2.0)。这是一个C ++,它以某种方式使它与许多其他dotnet不同(我不知道如何 - 我根本不了解C ++)。
将该解决方案升级到4.5并重建后,一切正常。
