在Azure Web Api App中引用原生64位dll
问题描述：
我创建了一个使用原生64位dll的Azure Web API应用程序。我能够在没有任何问题的情况下在本地运行服务。但是，当我尝试在Azure上托管它时，出现以下错误。在Azure Web Api App中引用原生64位dll
有一个thread与一个已知的问题有关在Azure应用程序内加载本机DLL。我按照解决方案创建了一个XDT脚本来将bin文件夹（D：\ home \ site \ wwwroot \ bin）添加到PATH中。不幸的是，这并没有帮助。
我使用Azure Portal Console验证了我的dll位于应用程序的bin文件夹中。我也在Kudu验证我的应用程序看到更新的路径。我确保Azure Portal内的应用程序设置设置为64位。如果我将应用程序设置重新设置为32位模式，它会发现dll并引发错误的格式错误，因此似乎存在引用Azure中的本机64位dll的问题。
我收到以下错误，当我尝试调用我的应用程序：

答
的问题是，我已编译的DLL的调试和不释放造成他们引用VCRUNTIME [...] D和MSVCP D调试DLL，这些DLL在Azure中不可用。重新编译Release中的DLL解决了这个问题。
