将ImageResizer与ASP.NET MVC中的视图预编译一起使用

Question

我在ASP.NET MVC网站中使用ImageResizer库 。 我试图打开视图预编译以加快首页加载时间，并且图像缩放器停止工作。 尝试访问调整大小的图像时收到以下404消息：

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

在ImageResizer的调试输出（如下所示）中，它显示“（警告）：启用了预编译。图像提供程序可能无法按预期运行。”

有什么办法可以使他们一起工作？

故障排除指南说，找不到文件错误可能是因为“（a）您未指定命令字符串，（b）启用了预编译，并且（c）使用了图像提供程序。这是由于长期存在的原因.NET框架中的错误。” 什么是命令字符串？ 如果指定命令字符串，它将起作用吗？ 如果是这样，我该怎么做？

调试输出：

预编译会破坏所有VirtualPathProvider。 我们已经进行了各种缓解措施，但是您切断了ImageResizer的版本号，因此在此我无济于事。

如果您切换到异步HttpModule，则可能会有更多运气。

替换type="ImageResizer.InterceptModule"/>与type="ImageResizer.AsyncInterceptModule"/> Web.config中。
