c# - dotnet 4.5 的混合模式装配问题

标签 c# winforms c#-4.0 visual-studio-2015 app-config

我刚刚将我的 C# winforms 应用程序从 dotnet 2.0 (VS2010) 升级到 dotnet 4.5 (VS2015)。我现在在尝试运行它时遇到此错误:

Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration

经过大量研究后，我明白了，因为我的 dotnet 4.5 应用程序引用了使用 dotnet 2.0(我认为是 3.0 或 3.5)构建的代码。解决方案(根据我所阅读的内容)是向 app.config 文件添加一些文本。但无论我添加什么(每次都关闭应用程序)，它都不起作用。

到目前为止，我已经尝试过(排名不分先后):

  <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" />

我已经没有什么可以尝试的了。

我不确定这是否相关，但是当我将鼠标悬停在某些区域上时，我的 App.config 文件会给我警告，给我这样的消息:

Imported schema for namespace 'urn:schemas-microsoft-com:asm.v1' was not resolved.

我在另一篇帖子中提出了这个问题，但有人说这不应该成为问题。下面是这个的快速截图: Mouseover message

如有任何帮助，我们将不胜感激。

我当前的 App.config 如下所示:

最佳答案

问题最终是我使用的一个特定的 dll (dotnet v2.0)。它是一个 C++ 的，以某种方式使它与许多其他 dotnet 不同(我不知道 - 我根本不了解 C++)。

将该解决方案升级到 4.5 并重新构建后，一切正常。
