无法加载文件或程序集“JsonFx.Json”或其依赖项之一。试图加载格式不正确的程序。

Question

我正在尝试编译和运行一个包含一些外部DLL的web应用程序。

应用程序编译时没有错误，但是当我运行它时，我会收到以下错误：

无法加载文件或程序集“JsonFx.Json”或其依赖项之一。试图加载格式不正确的程序。

解决此问题的两种最常见的解决方案似乎是在IIS服务器中启用32位应用程序，并确保解决方案不是以32位模式编译某些项目，而在64位模式下编译其他项目。这两种我都试过了，但都没有用。

任何帮助都将不胜感激。

Answer 1

我通过重新下载JsonFx.Json.dll来解决这个问题。我仍然不太清楚为什么它现在起作用了，这比一开始就不起作用更让人不舒服。

Answer 2

我假设您是在Visual的IIS Express中运行此操作。如果将项目设置为编译为64位而不是32位，则需要启用64位IIS Express。

步骤：

1. 导航到：HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\12.0\WebProjects
2. 确保有一个名为“REG_DWORD”的Use64BitIISExpress值。如果没有，就创建它。
3. 将其值设置为1(默认值= 0)。
