问题 I have a web service, like this example for downloading a zip file from the server. When i open the URL through web browsers,I can download the zip file correctly.

问题 I'm building a .NET Web API using Entity Framework 6 with AutoMapper to map entities to DTOs. When I try to introduce an TPH (table per hierarchy) with an abstract base class, I get a very long and very useless (to me at least) error. The error is below, I'm not sure what the actual error is. I've tried Googling various sections of it to no avail. This is my mapping: Mapper.CreateMap<ParentClass, ParentClassDTO>() .Include<ClassA, ClassADTO>() .Include<ClassB, ClassBDTO>(); Mapper.CreateMap

问题 Let's say I have a Todo model with a corresponding Todo table ( DbSet<Todo> ) in an EF-generated database. The table will store a todo item per row. Each user (in an ASP.NET Core Identity + IdentityServer app) will be associated with multiple todo items (one-to-many, a user can have multiple todo items). The way I'd do it is to add a UserId foreign key to the Todo model that represents the user that owns the todo item . How would I do that with EF Core while utilizing the classes proved by

问题 I've noticed that many developers subclass the AuthenticationStateProvider both in Blazor Server App and Blazor WebAssembly App wrongly, and more imprtantly for the wrong reasons.
