在ASP.NET MVC中使用ImageResizer进行视图预编译

Question

我在我的ASP.NET MVC网站中使用了ImageResizer library。我试图打开视图预编译来加速首页加载时间，图片缩放器停止工作。我得到试图访问一个调整图像时以下404消息：从ImageResizer它说：“（警告）

The resource you are looking for has been removed, had its name changed, or is temporarily unavailable. 

在调试输出（如下图所示）：预编译启用预期影像提供商可能无法正常工作。 “

有没有什么办法让他们一起工作？

故障排除指南指出找不到文件错误可能是因为“您（a）未指定命令字符串，（b）已启用预编译，以及（c）正在使用图像提供程序。 .NET框架中一个长期存在的bug。“什么是命令字符串？如果我指定一个命令字符串，它会起作用吗？如果是这样，我该怎么做？

调试输出：

预编译打破了所有VirtualPathProviders。我们已经完成了各种缓解措施，但是您切断了ImageResizer版本号，所以我在这方面帮不了什么忙。

如果你切换到Async HttpModule，你可能会有更多的运气。

在Web.config中将type="ImageResizer.InterceptModule"/>替换为type="ImageResizer.AsyncInterceptModule"/>。
