Question

我创建了一个使用本机64位dll的Azure Web API应用程序。我可以在本地运行该服务，没有任何问题。但是，当我尝试在Azure上托管它时，我得到以下错误。

有一个thread，其中包含有关在Azure应用程序中加载本机DLL的已知问题。我按照解决方案创建了一个XDT脚本，将bin文件夹（D：\ home \ site \ wwwroot \ bin）添加到PATH。不幸的是，这没有帮助。

我使用Azure Portal Console验证了我的dll在应用程序的bin文件夹中。我还在Kudu验证了我的应用程序看到了更新的路径。我确保Azure门户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，它会找到dll并引发不正确的格式错误，因此似乎存在一些引用Azure内部本机64位dll的问题。

当我尝试拨打我的应用时出现以下错误：

问题是我已经将DLL编译为Debug而不是Release，导致它们引用了Azure中不可用的VCRUNTIME D和MSVCP D调试DLL。在Release中重新编译DLL解决了这个问题。

在Azure Web Api App中引用本机64位dll
