asp.net-core-2.2

问题 I'm migrating a full .NET Framework Web API 2 REST project over to ASP.NET Core 2.2 and getting a bit lost in the routing. In Web API 2 I was able to overload routes with the same number of parameters based on the parameter type, e.g. I could have Customer.Get(int ContactId) and Customer.Get(DateTime includeCustomersCreatedSince) and incoming requests would be routed accordingly. I haven't been able to achieve the same thing in .NET Core, I either get a 405 error or a 404 and this error

问题 I have an application written using C# on the top of ASP.NET Core 2.2 framework. I am using Identity to user management and user control. Currently, everytime a user closed his/her browser and open the app again, they are required to log in again.

Here is what I have added to the Startup class public void ConfigureServices(IServiceCollection services) { services.AddDbContext

问题 My swagger ui shows "Parameter content type" with various entries: "application/json-patch+json" , "text/json" , "application/json" , and "application/*+json" . I only want "application/json" . There's a similar unsolved issue on the repo, which uses this visual (older ui, but same idea): Is there some way to set this? Swashbuckle.AspNetCore version 4.0.1 Swashbuckle.AspNetCore.Filters version 4.5.5 回答1: Use the [Produces] and [Consumes] attributes. Swashbuckle (and others, like NSwag) will

问题 I would like to be able to populate the User Id field in Application Insights with my real username data. This is an internal application, so privacy concerns with a simple username field are moot. As far as I can tell, all solutions available online for this strictly work in .NET Framework, not .NET Core. You can find this solution in a few places, including some old AI documentation on GitHub. However, when I run it, I get an error on startup indicating that dependency on the scoped object

问题 I created an .Net Core Web Api with an Angular ClientApp with the templates from Visual Studio. When building the project also builds the contained Angular App with the params set in the .csproj <Target> section e.g. <Target Name="PublishRunWebpack" AfterTargets="ComputeFilesToPublish"> <!-- As part of publishing, ensure the JS resources are freshly built in production mode --> <Exec WorkingDirectory="$(SpaRoot)" Command="npm install" /> <Exec WorkingDirectory="$(SpaRoot)" Command="npm run
