问题 I have image data being stored in a SQL table with a field type of varbinary(max) I also store the image content type. Using Microsoft ASP.NET Core MVC and Dapper, I am trying to get the file back from the database and render it as an image. This is my FileModel : using System; namespace Brand.Models { public class FileModel { public Guid ID { get; set; } public string FileName { get; set; } public string FileType { get; set; } public byte[] FileData { get; set; } public int FileLength { get;

问题 What's the best practice for using the ASP.NET Core bundleconfig.json with development versus production environments? The prior bundler (BundleCollection) would pay attention to the DEBUG compiler directive and not minify the list of scripts when you're debugging. It appears as though the new paradigm is to have <environment> tags in the HTML templates that test for the ASPNETCORE_ENVIRONMENT value. Though I don't see a way of incorporating that environment variable into the bundleconfig

问题 In ASP.NET MVC 5 is possible to obtain some dependency through DependencyResolver.Current.GetService<T>() . Is there something similar in ASP.NET Core? 回答1: Yes, there is.

问题 Scenario: implementing a standard REST API / GET method on a .net core controller. The documentation states that OkObjectResult is an ObjectResult with status 200. This is available through the Ok(myResult) method inherited from ControllerBase. I assume this is a convenience method. However, the tutorial is not using this approach - it instead returns new ObjectResult(myResult) which will default to status 200. Is there any difference between these two approaches? 回答1: Technically there is no

问题 I am trying to implement Entity Framework 7 in MVC 6, and on this page here it says to do services.AddEntityFramework() .AddSqlServer() .AddDbContext<MusicStoreContext>(options => options.UseSqlServer(Configuration["Data:DefaultConnection:ConnectionString"])); But for me, the UseSqlServer method isnt visible?

问题 Question: Is there any way to assign two different routes (with parameters) to the same controller in an ASP.NET MVC 6 application? I Tried: I tried using multiple route attributes to the controller class and also to the individual actions, did not work. Notes: I am using ASP.NET Core 1.0 RC1.

Example: [Produces("application/json")] [Route("api/v2/Log")] /// The old

问题 cI went through various posts regarding the Areas routing but still I am not able to resolve my issue. I would like to split my application in the way that there are two routes. /Areas/Panel /Areas/Website Inside each area there is HomeController and appropriate methods that correspond to actions. I would like that whenever user lands to any level 1 route i.e.: /home /contact /about/company etc. is directed to /Areas/Website/{controller}/{action} and alternatively for /panel /panel/home
