问题 I am trying to replace my view components with razor pages but it seems that it's not possible to load a partial razor page because a model is expected to be passed yet it is my understanding that the model for a razor page should be declared in the OnGetAsync method. Here is my code... Razor Page @page "{id:int}" @model _BackgroundModel <form method="POST"> <div>Name: <input asp-for="Description" /></div> <input type="submit" /> </form> Razor Page Code-Behind public class _BackgroundModel :

问题 I am trying to create a valdiation attribute in my Core 2 project. It needs to validate the value against a list of existing values held in the database. The code below isn't working, it isn't able to access the DB Context. Any ideas why/how to correct? public class BibValidatorAttribute : ValidationAttribute { protected override ValidationResult IsValid( object value, ValidationContext validationContext) { RaceEntryViewModel raceEntry = (RaceEntryViewModel)validationContext.ObjectInstance;

问题 I am trying to create some Quartz.Net jobs following my own answer from this question. However, if the job is fairly complex and required "scoped" ( services.AddScoped<.., ...> ) services, the example does not work because jobs are created as singletons. If I change them to be scoped, the serviceProvider does not contain the services I need. I have managed to make it work using the following code: Startup.cs /// <summary> /// service provider to be used by qiaryz job factory which cannot use

问题 I have been developing an application with Azure Cosmos DB using the Emulator with good success - I've been able to create the database & collections and add documents to the collections as well as read those documents. the trouble now is that I've tried to swap the emulator out for a live instance of Azure Cosmos DB and I am getting an error whilst trying to create the database.

问题 I like the new tag helpers attributes which make readable dynamic html contents. I can create a link by using the asp-controller and asp-action attributes like this: <a asp-controller="Home" asp-action="Index">Index</a> The problem is that there are cases where I need just the URL of the action in order to use it my javascript. For example in order to make an ajax call in ASP.NET MVC 5, I could have the following code: $.ajax({ type: "POST", url: '@Url.Action("GetData","Ajax")', data: "{ }",

问题 I have in incoming bearer token that has an incorrect audience. There is enough information in the token via other claims that prove what the audience should be. I was hoping to fix it up early so that I could still take advantage of the JwtBearerOptions.TokenValidationParameters.ValidateAudience = true; JwtBearerOptions.TokenValidationParameters.ValidAudiences ={"the right one"}; I can hook the OnTokenValidated event, and rewrite the principal, but that is too late. Earlier in the pipeline

问题 Multi-Tenant Authentication I have created a new tenant from the swagger UI as an admin and I can check in the data the tenant created successfully together with admin account . Now how do I login as the admin of the newly created tenant? Cos I tried Token-authenticating via Postman, specifying tenancyName in the request body and it only seems to authenticate the admin from default tenant - even when I put in rubbish in the tenancyName field, it won't detect any error or exception.

问题 Using the ASP.NET Core 2.0 template for creating react app with redux i want to use the webpack-dev-server which is used in the react CRA (CREATE REACT APP) .

问题 I have a .Net Core 1.1 project using VS 2017 EF Core. When I created a new view, I received the does not exist in current context error on the ViewData, the Model, and even the @model. In trying to fix the problem, I ended up updating my packages which only gave me more errors to resolve. I'm not running .Net Core 2.0 because of the update. The other views in my project are not having this issue. I created only one other view and I ended up having the same problem with it, but just on @model
