Nested layouts for MVC5

阅读更多关于 Nested layouts for MVC5

问题 I've seen a few posts on this topic: Razor Nested Layouts with Cascading Sections MVC 3 - Nested layouts - sections don't render in Areas And it always seems to be problematic. However they are both pretty old so wondering if things have changed. Basically I have a master layout, and 3 different body templates based on what kind of page it is. For examples sake: _Layout.cshtml <html lang="en"> <head> </head> <body style="padding: 50px 0;"> <header class="navbar navbar-default navbar-fixed-top

阅读更多关于 ASP.NET Identity 2 UserManager get all users async

You can either wrap it in your own asynchronous method: (this might be a bit evil) public async Task<IQueryable<User>> GetUsersAsync { return await Task.Run(() => { return userManager.Users(); } } Or use the ToListAsync extension method: public async Task<List<User>> GetUsersAsync() { using (var context = new YourContext()) { return await
