ASP.NET Web API – FileNotFoundException：无法加载文件或程序集

Question

我正在macOS Mojave（10.14.6）上使用Visual Studio for Mac [Community]版本8.2.3。

我创建了一个ASP.NET Core API解决方案。我需要访问第三方DLL并将其添加到我的项目中-它显示在“依赖项/程序集”下。我正在通过POST方法访问它。

项目构建良好。在调试模式下运行并访问POST URL时，出现以下错误：

我想念/做错了什么？

Answer 1

尝试清洁溶液并重建。有时重新启动Visual Studio也会清除此类问题。 如果您正在使用nuget之类的任何程序包管理器进行安装，请参阅packages.config文件中已添加程序集或在config中添加从属程序集文件。查看bin中的构建文件是否具有此dll。

Answer 2

An attempt was made to load a program with an incorrect format.

用户错误。我的。

我应该一直在使用x64 DLL，而在使用x86 DLL。看来已经解决了。
