  • This article should how SignalR 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.
  • 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.
  • A single SignalR Hub is used to add the logic to send the direct messages between the clients.
  • All other online clients are sent a message, with the new user data.

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 Microsoft.AspNetCore.SignalR 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.

The actual client is sent the complete list of existing clients.
