【问题描述】:
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:
混合模式程序集是针对版本“v2.0.50727”构建的 运行时并且不能在没有额外的 4.0 运行时加载 配置
经过大量研究后,我明白这是因为我的 dotnet 4.5 应用程序引用了使用 dotnet 2.0(或者我认为是 3.0 或 3.5)构建的代码。解决方案(根据我所阅读的内容)是将一些文本添加到 app.config 文件中。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(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" />
我要尝试的东西已经不多了。
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,给我如下消息:
命名空间“urn:schemas-microsoft-com:asm.v1”的导入架构是 没有解决。
我在另一个帖子中提出了这个问题,但有人说这应该不是问题。下面的快速截图: Mouseover message
任何帮助将不胜感激。
我当前的 App.config 如下所示:

【问题讨论】:
-
当然。我已更新我的帖子以包含 App.config。
-
这是我读过的一篇关于此的文章,我尝试过在 app.config 中添加的建议。
-
作为进一步的实验,我删除了我的 App.config 并重新开始。现在我所拥有的只是启动节点。所以看起来它不是 App.config 中引起冲突的其他东西。这就是我的 app.config 的全部内容:
<?xml version="1.0" encoding="utf-8" ?> <configuration> <startup useLegacyV2RuntimeActivationPolicy="true"> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/> <requiredRuntime version="v4.0.20506" /> </startup> </configuration> -
MyApp.Data 也是 dotnet 4.5。我已将此解决方案中的每个项目升级到 dotnet 4.5,除 winforms 项目外,其他所有项目都可以正常编译。其他项目也引用了 dotnet 2.0 dll,但他们没有遇到同样的问题。
-
对不起 - 也许我之前的评论不清楚。我的意思是我把所有东西都去掉了,除了启动位,我仍然得到错误。
