这些是我产生这个错误所遵循的步骤
检查 VS 2017 是否是最新的
创建一个新的 asp.net web 应用程序,选择 MVC,然后 F5 调试应用程序而不做任何更改。我看到不同的 CSS 文件没有捆绑或缩小。
更改 web.config 以通过更改 debug = false 来缩小和捆绑
<compilation debug="false" targetFramework="4.6.1"/>
F5 -> 查看站点,我看到一个 CSS 文件,其中的内容被缩小了。
停止调试
从 VS -> Tools -> NuGet Package Manger -> Manage NuGet Packages 获取解决方案。
我看到 14 个更新,其中一个是我们想在项目中使用的 bootstrap v4。更新所有包
包更新后F5不调试
查看源码 -> CSS 文件被打包成一个文件 -> 查看 CSS 文件,你会看到一个错误

根据这个post该问题已在 BundlerMinifier 中修复,但我没有那个包或 Nuglify,缩小和捆绑似乎仍然发生。
开箱即用而不做任何更改应该是直截了当的,但事实并非如此。
我在这里错过了什么?
最佳答案
这是一个内置的 C# 问题。他们使用他们的类来压缩 css。我找到了问题的解决方案。您必须创建自己的类(class)
public class MyStyleBundle : Bundle
{
public MyStyleBundle(string virtualPath) : base(virtualPath, new MyCssMinify())
{
}
public MyStyleBundle(string virtualPath, string cdnPath) : base(virtualPath, cdnPath, new MyCssMinify())
{
}
}
public class MyCssMinify : IBundleTransform
{
internal static readonly MyCssMinify Instance = new MyCssMinify();
internal static string CssContentType = "text/css";
public virtual void Process(BundleContext context, BundleResponse response)
{
if (context == null)
{
throw new ArgumentNullException("context");
}
if (response == null)
{
throw new ArgumentNullException("response");
}
if (!context.EnableInstrumentation)
{
// CssCompress.Go- This is your CSS compression implementation
// You can use the library " Uglify"
response.Content = CssCompress.Go(response.Content);
}
response.ContentType = CssContentType;
}
}
现在你可以添加一个新的Bundle
bundles.Add(new MyStyleBundle("~/Content/css").Include(
"~/Content/bootstrap.css",
"~/Content/site.css"));
