问题 This question already has answers here : How do you create a custom AuthorizeAttribute in ASP.NET Core? (8 answers) Closed 2 years ago . I'm building an API in .NET Core 1.1.

问题 I have an ASP.NET MVC 6 project with the following structure: project/ wwwroot/ custom/ project.json I want to serve files from custom as it if was a virtual folder into http://localhost/custom without having to copy them during development.

问题 I have 3 solutions. Project.Web, Project.Core (Business), and Project.Layer(Models). In Project.Core, I have a static file that I can call like this Business.GetAllData(); from Project.Web.Controller. This calls DAL/EF files and gets data( BusinessDal.GetData() ). using (DBContext db = new DBContext()) { return db.GetAllData().ToPOCO(); } On my configuration/DbContext.cs, I have this: protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder) { #if DEBUG optionsBuilder

问题 I'm having two controller controllers: ControllerA and ControllerB . The base class of each controller is Controller . The ControllerA needs to return JSON in the default format (camelCase). The ControllerB needs to return data in a different JSON format: snake_case. How can I implement this in ASP.NET Core 2.1? I've tried the startup with: services .AddMvc() .AddJsonOptions(options => { options.SerializerSettings.Converters.Add(new StringEnumConverter()); options.SerializerSettings

问题 On a plain vanilla, scaffolded ASP.NET Core MVC web app, with a DbContext registered in the DI container, whenever I hit F5 after 30-60 seconds, I get the error message: Unable to start program 'http://localhost:60175/'. Operation timed out. The home page in an index view, whose action gets all employees from a localhost SQL Server db. The project is already built, so the initial build for debug is quite quick, and doubtfully the cause of the delay. If I run without debugging, I get the home

问题 I am porting some code from .NET 3.5 - 4.5. Inside of my assembly, I have some code that reads the resource from the currently executing assembly. However, GetExecutingAssembly() isn't a method on the Assembly type in DNX core 5.0. var xsdStream = Assembly.GetExecutingAssembly().GetManifestResourceStream(xsdPath); What is the equivalent of Assembly.GetExecutingAssembly() in DNX core 5.0? Or if I need a namespace to get that method back (an extension method perhaps?), what is the namespace?

问题 I have a situation where a site may need a link to redirect to certain controllers based on database results. For example: site.com/abcd needs to return the result from a Item Controller, which would normally be called as /item/view/123 The key here is that I can't hard code the abcd into the routing. And some links may go to an Item Controller, others may go to an Orders controller. I've tried a catchall route to a controller than then loads up the desired controller, but the environment is
