dotnet core Razor类库的视图找不到

Question

开发环境 win10 vs2017
我在一个解决方案里,做了一个Razor类库，做了一下ui。debug模式下生成了 lib.dll和lib.views.dll
同一个解决方案中，另一个mvc的网站项目，引用了 此项目，显示没有问题。
另一个解决方案中，一个mvc的网站项目，引用了 lib.dll和lib.views.dll,但是显示错误，找不到cshtml

在VCardCoreWeb中的_ViewStart.cshtml中

VCardCoreWeb 运行是没有问题的，可以找到这个_Layout.cshtml

但是在另外一个解决方案的项目中，就显示找不到_Layout.cshtml

这个怎么解决？？

Answer 1

 public static void AddVCardO2OUI(this IServiceCollection services)
        {
            services.Configure<RazorViewEngineOptions>(
                o =>
                {
                    o.AreaViewLocationFormats.Clear();
                    o.AreaViewLocationFormats.Add("~/Areas/{2}/Views/{1}/{0}" + RazorViewEngine.ViewExtension);
                    o.AreaViewLocationFormats.Add("~/Areas/{2}/Views/Shared/{0}" + RazorViewEngine.ViewExtension);
                    o.AreaViewLocationFormats.Add("~/Areas/{2}/Views/Shared/BasePage/{0}" + RazorViewEngine.ViewExtension);
                    o.AreaViewLocationFormats.Add("~/Views/Shared/{0}" + RazorViewEngine.ViewExtension);
                    o.AreaViewLocationFormats.Add("~/Views/Shared/BasePage/{0}" + RazorViewEngine.ViewExtension);

                    o.AreaViewLocationFormats.Add("~/Areas/{2}/O2OViews/{1}/{0}" + RazorViewEngine.ViewExtension);
                    o.AreaViewLocationFormats.Add("~/Areas/{2}/O2OViews/Shared/{0}" + RazorViewEngine.ViewExtension);
                    o.AreaViewLocationFormats.Add("~/Areas/{2}/O2OViews/Shared/BasePage/{0}" + RazorViewEngine.ViewExtension);

                    o.AreaViewLocationFormats.Add("~/O2OViews/Shared/{0}" + RazorViewEngine.ViewExtension);
                    o.AreaViewLocationFormats.Add("~/O2OViews/Shared/BasePage/{0}" + RazorViewEngine.ViewExtension);

                    o.ViewLocationFormats.Clear();

                    o.ViewLocationFormats.Add("~/Views/{1}/{0}" + RazorViewEngine.ViewExtension);
                    o.ViewLocationFormats.Add("~/Views/Shared/{0}" + RazorViewEngine.ViewExtension);
                    o.ViewLocationFormats.Add("~/Views/Shared/BasePage/{0}" + RazorViewEngine.ViewExtension);

                    o.ViewLocationFormats.Add("~/O2OViews/{1}/{0}" + RazorViewEngine.ViewExtension);
                    o.ViewLocationFormats.Add("~/O2OViews/Shared/{0}" + RazorViewEngine.ViewExtension);
                    o.ViewLocationFormats.Add("~/O2OViews/Shared/BasePage/{0}" + RazorViewEngine.ViewExtension);
                });
        }

将 O2OView 改成自己的

另外，我用了nuget，直接引用dll，view.dll 不知道会不会出现问题
