This article should how could be used to send direct messages between different clients using ASP.NET Core to host the SignalR Hub and Angular to implement the clients. Code: https://github.com/damienbod/AspNetCoreAngularSignalRSecurity Other posts in this series: When the application is started, different clients can log in using an email, if already registered, and can send direct messages from one SignalR client to the other SignalR client using the email of the user which was used to sign in. All messages are sent using a JWT token which is used to validate the identity. The latest Nuget package can be added to the ASP.NET Core project in the csproj file, or by using the Visual Studio Nuget package manager to add the package. <PackageReference Include="Microsoft.AspNetCore.SignalR" Version="1.0.0-alpha2-final" /> A single SignalR Hub is used to add the logic to send the direct messages between the clients. The Hub is protected using the bearer token authentication scheme which is defined in the Authorize filter. A client can leave or join using the Context.User.Identity.Name, which is configured to use the email of the Identity. When the user joins, the connectionId is saved to the in-memory database, which can then be used to send the direct messages. All other online clients are sent a message, with the new user data. The actual client is sent the complete list of existing clients. using Microsoft.AspNetCore.Authorization; using Microsoft.AspNetCore.SignalR; using System.Collections.Generic; using System.Linq; using System.Threading.Tasks; namespace ApiServer.SignalRHubs { [Authorize(AuthenticationSchemes = "Bearer")] public class UsersDmHub : Hub { private UserInfoInMemory _userInfoInMemory; public UsersDmHub(UserInfoInMemory userInfoInMemory) { _userInfoInMemory = userInfoInMemory; } public async Task Leave() { _userInfoInMemory.Remove(Context.User.Identity.Name); await Clients.AllExcept(new List<string> { Context.ConnectionId...
We are very excited to announce that today we are publicly releasing a statement in regards to our newest created role here at Grand Apps & KREATIV, which is our Chief Marketing Officer.

This post exists to provide hope. After the somewhat hesitant reaction to last week’s webpack post, this post highlights two great Angular and ASP.NET Core starter templates. These starter projects not only contain configurations for webpack 1 and webpack 2, there are a ton of other Angular and ASP.NET features implemented for you. ASP.NET Core Template Pack The first project template to note comes from the ASP.NET Core Template Pack by Mads Kristensen. The template pack is a Visual Studio Extension containing multiple templates for ASP.NET Core. The collection includes a helpful Angular template. Key Features The hallmark feature of the template is Angular Universal. This framework enables server-side Angular rendering when the application is initially requested from the server. Angular Universal decreases the initial page load time by rendering the first request on the server instead of requiring the client to wait for the application to download before rendering. Subsequent route changes are all rendered client-side. For any application that requires minimum load times, this framework is a must-see. The template also uses webpack version 1. For anyone working on integrating webpack into their applications, every example helps. This template doesn’t use the latest loaders that the folks on the Angular side of the community are using. It does however accomplish the primary goal by compiling combined scripts. And being that it’s using Angular Universal, there are webpack configurations for both the client application and the server rendering portion. The template also implements webpack’s hot module replacement feature. This is a development feature where the client-side code is replaced in the browser via a WebSocket when the source...

At Microsoft Build Live today, we are sharing a first look at our plans for .NET Core 3. The highlight of .NET Core 3 is support for Windows desktop applications, specifically Windows Forms, Windows Presentation Framework (WPF), and UWP XAML. You will be able to run new and existing Windows desktop applications on .NET Core and enjoy all the benefits that .NET Core has to offer. We are planning on releasing a first preview of .NET Core 3 later this year and the final version in 2019. We will be looking for developers to partner with us, to give us feedback, and to release versions of your applications in the same timeframe as our releases. We think that .NET Core 3.0 will be one of the most exciting .NET releases we’ve ever released. ASP.NET Core will continue to move forward in parallel and will have a release with .NET Core 3.0. Our commitment to web and cloud applications remains unchanged. At the same time, it’s time to add Windows desktop applications as another supported workload for .NET Core. We have heard many requests for desktop applications with .NET Core and are now sharing our plan to deliver on that. Let’s take a look at that.
