我有一个WCF项目，它引用了2个项目。
此项目是FaceSDK.NET第三方图书馆的参考。我在另一个项目中使用了这个FaceSDK.NET dll文件。但它需要插入App.config
<startup useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
<supportedRuntime version="v2.0.50727"></supportedRuntime>
</startup>
我想在我的WCF项目中使用库项目中的功能。当我构建项目时，它构建良好。但是当它在WCF测试客户端上运行时，它会产生如下错误。

有人认为这是由于目标平台不兼容。我试图将它保持在一个平台上。我也尝试添加一个App.confing文件，但没有用。非常感谢帮助。
在this帖子中，有一个类似的问题，但这与WCF有关。
编辑：
我会添加更多信息。这个项目A使用EmguCV包装器。当我将OpenCV文件（这些是500MB）显式添加到WCF服务的bin时，它会出现上述错误。当我删除这些文件然后只放置项目引用时，错误有点不同。

答案 0 :(得分：0)
虽然看起来还有其他几个错误，但主要问题是硬件功能较弱。我不得不将我的硬件格式从4GB升级到8GB，并且工作正常。
