问题 It seems that .NET (Core 3.1) supports custom curves in ECC. So I've defined the Curve25519, and generated key pair by below code: using System; using System.Security.Cryptography; namespace Curve25519 { class Program { static void Main(string[] args) { ECCurve ecCurve = new ECCurve() // Curve25519, 32 bytes, 256 bit { CurveType = ECCurve.ECCurveType.PrimeMontgomery, B = new byte[] { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1 }, A = new byte

问题 I'm trying to add long cache headers to static .css and .js files using StaticFileOptions From various SO and other articles, this is how you do it: app.UseStaticFiles(new StaticFileOptions { OnPrepareResponse = ctx => { const int durationInSeconds = 60 * 60 * 24; ctx.Context.Response.Headers[HeaderNames.CacheControl] = "public,max-age=" + durationInSeconds; } }); However, I am using a bunch of static files provided by a RCL. The RCL has a StaticServing.cs class which I have used from this

问题 Consider a scenario where you are implementing code meant to be used for machine to machine communication. The typical example for that is the code executed inside a web API action method. Suppose that you want to perform an exact match between strings; maybe you have a list of users and you wan to find one specific user provided the user name: List<User> users = .... const string username = "user-123"; var user = users.Find(u => string.Equals(username, u.UserName)); In such a scneario should

问题 Update : Even a new .net core web application is showing the same error. I'm using .Net Core Version 1.0.0-preview2-003131. I upgraded a .Net Core SDK from Version 1.0.0-preview2-003121 to the above mentioned. Now when I try to run the application I get the error: ERR_CONNECTION_REFUSED When I searched on Internet most of the stuff is to change the Port number. I change that and it still doesn't work. Any ideas how to fix this? The project.json file is: { "userSecretsId": "aspnet-Angle_MVC6

问题 I need to add custom claims to my Azure B2C users, so I figured the way to do this is to add schema extensions to the User for my directory App with Graph API (beta). I wrote a simple test for that: SchemaExtension schemaExtension = new SchemaExtension { Id = schemaName, Owner = _appClientId.ToString(), Description = string.IsNullOrWhiteSpace(schemaDesc) ? string.Empty : schemaDesc.Trim(), TargetTypes = new List<string> { "User" }, Properties = new List<ExtensionSchemaProperty> { new

问题 For an Azure Functions project I am using C# 8 with enabled nullable reference types. Since with AzureFunctions AppSettings are exposed via environment variables, which can be a string or null (i.e. they return string? ) I tried to encapsulate the logic of getting environment variables - and throwing an error if they're not set - into a separate method GetEnvVariable . As you can see, GetEnvVariable is implemented in three short lines. If the environment variable is not set (i.e it is null )
