Asp.net mvc 引导程序4未在Razor视图中渲染,asp.net-mvc,razor,bootstrap-4,Asp.net Mvc,Razor,Bootstrap 4,我已从引导3更新到引导4，现在Razor视图将无法正确渲染，如下图所示：正如您所看到的，所有引导样式都消失了，导航栏也消失了。这与Bootstrap 3很好这只是MVC项目附带的标准登录页面，所以我没有添加任何花哨的内容我的包如下： using System.Web; using System.Web.Optimization; namespace FoodSnap { public class BundleConfig { // For more information on

我已从引导3更新到引导4，现在Razor视图将无法正确渲染，如下图所示：

正如您所看到的，所有引导样式都消失了，导航栏也消失了。这与Bootstrap 3很好

这只是MVC项目附带的标准登录页面，所以我没有添加任何花哨的内容

我的包如下：

using System.Web;
using System.Web.Optimization;

namespace FoodSnap
{
public class BundleConfig
{
    // For more information on bundling, visit https://go.microsoft.com/fwlink/?LinkId=301862
    public static void RegisterBundles(BundleCollection bundles)
    {
        bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
                   "~/Scripts/jquery-{version}.js",
                   "~/Scripts/jquery-ui-{version}.js"));

        bundles.Add(new ScriptBundle("~/bundles/modernizr").Include(
            "~/Scripts/modernizr-*"));

        bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(
             "~/Scripts/bootstrap.js",
             "~/Scripts/respond.js"));


        bundles.Add(new StyleBundle("~/Content/css").Include(
            "~/Content/bootstrap.css",
            "~/Content/site.css",
            "~/Content/themes/base/jquery-ui.css"));
    }       

}

}

在我看来，我的看法如下：

using System.Web;
using System.Web.Optimization;

namespace FoodSnap
{
public class BundleConfig
{
    // For more information on bundling, visit https://go.microsoft.com/fwlink/?LinkId=301862
    public static void RegisterBundles(BundleCollection bundles)
    {
        bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
                   "~/Scripts/jquery-{version}.js",
                   "~/Scripts/jquery-ui-{version}.js"));

        bundles.Add(new ScriptBundle("~/bundles/modernizr").Include(
            "~/Scripts/modernizr-*"));

        bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(
             "~/Scripts/bootstrap.js",
             "~/Scripts/respond.js"));


        bundles.Add(new StyleBundle("~/Content/css").Include(
            "~/Content/bootstrap.css",
            "~/Content/site.css",
            "~/Content/themes/base/jquery-ui.css"));
    }       

}

我尝试了很多东西，包括CDN，结果都是一样的。以前有人见过吗？

引导程序4几乎是对引导程序3的完全重写，这意味着：

引导程序3的代码都与引导程序4不兼容
