asp.net-core-2.0

问题 I've just upgraded to ASP.NET Core 2 Preview 2 and ran into a problem with the depedency injection. I get Could not resolve a service of type 'LC.Tools.API.Data.GenericDbContext' for the parameter 'context' of method 'Configure' on type 'LC.Tools.API.Startup' when running the project.

问题 I was following some tutorials on IdentityUser, and I think I did exactly as in tutorials, but when I try to login, I get "MyIdentity: False" (with LogInformation) even thou _signInManager succeeds, which seems to be very weird. I tried to set the users as confirmed, but with no result. I'm working on Visual Studio on Mac. Here's how I register my users: [HttpPost] [AllowAnonymous] [ValidateAntiForgeryToken] public async Task<IActionResult> Register(RegisterViewModel model) { if (ModelState

问题 I accessed appsettings.json In .NET Core 2 Web API Controller simply by adding below: public class MyController : Controller { private readonly IConfiguration appConfig; public MyController(IConfiguration configuration) { appConfig = configuration; } } Without adding below in Startup class ConfigureServices(IServiceCollection services) after services.AddMvc();: services.AddSingleton<IConfiguration>(Configuration); Is there any flaws in my approach?

问题 I'm trying to port an existing WCF Web API (targeting .NET Framework 4.6.1) to ASP.Net Core 2 using Visual Studio 2017 (v15.4.5) and am having trouble figuring out good/common/supported ways to organize projects, and what types of project they should be.

问题 I want to execute an SQL command from Entity Framework Core 2.0, but I can't figure out how to do so. 1.- The reason why I need to, is that I want to delete all data from a database table, and using Context.remove or Context.removeRange would produce many calls to DB (one for each data in the table). 2.- I've read that there is a method .ExecuteSqlCommand to accomplish that, but that method is not present in my Context.Database (maybe in Core 2.0 it was removed?).

问题 When starting up a fresh .Net Core 2.0 project with Azure AD Authentication you get a working sample that can sign in to your tenant, great! Now I want to get an access token for the signed in user and use that to work with Microsoft Graph API. I am not finding any documentation on how to achieve this.

问题 I have a ASP.NET Core 2.0 webservice running on IIS. One of controller's methods looks more or less like this: [HttpGet()] public IActionResult Test() { // do some db updates and get data var result = DoSomeStuff(); // serialize data to byte array var output = Serialize(result); return File(output, "application/octet-stream"); } It does some database updates, query records from a table, serialize data and send them as a response.
