问题 Before ASP.NET Core MVC, we would use RazorGenerator to compile views into assemblies, and we would reuse those views in another project, by introducing a custom ViewEngine that would load the view from the assembly instead of file-system. In ASP.NET Core MVC there is this concept of pre-compiled views and it works out of the box for version 2.0 and creates an assembly that by convention has the name of project_name.PrecompiledViews.dll . I have two problems though that I can't find an answer

Wrong... When i put this into my razor (chstml or whatever it is). file and load the page

问题 This is my first time with MVC so please excuse me if I am getting the terminology wrong. I am working on a PluralSight course.

问题 I've done some research on this and seem to find posts that are either outdated or don't quite work in my situation. I may be using wrong keywords when searching though... =/ On my web page I have Tabs containing Group boxes that contain Lines which in turn contain Items. So it is lists of lists 4 levels. The problem: When posting back, ViewModel.Tabs is null and I can't save anything. Everything displays quite nicely, but nothing is posted back. The code Views/Shared/EditorTemplates/Tab

问题 I have looked around and found some close answers, but I haven't seen one yet like this: Using Entity Framework I have the following: A Role model: public class Role { [Key] public short RoleId { get; set; } public string RoleName { get; set; } public string RoleDescription { get; set; } } A User model: public class User { public int Id { get; set; } public string Name { get; set; } public string Email { get; set; } public string Username { get; set; } //more fields etc... public virtual
