SignalR not connecting? Things to check

SignalR is a websocket library for .NET. During setup and local development there are a number of issues you may encounter. In this post I’ll explain how to fix these. I will assume you are using ASP.NET core, version 2.2 or later. And your client is just plain old vanilla JavaScript . Obviously your first step should be reproducing your issue with new empty projects, where you can be sure nothing else is interfering. Beyond that, here are a few tips: Client Scripts Updated To use SignalR in JavaScript you should be have the official client-side library from Microsoft. This is usually a single file called signalr.js or signalr.min.js (the minified version). You can find basic HTML/JS example use here to check you are using it correctly. If you have got the client scripts from a non-official source, or there is a chance they might be out-of-date, make sure you replace them with the latest version. The best way is to obtain the latest version is to read Microsof

Local Storage Models in Blazor

Blazor is a new web framework by Microsoft which ships with .NET Core. In this post I explain how to use Local Storage in Blazor using the Blazored.LocalStorage package and how to improve on this by creating a custom service allowing you to use models (classes with properties) instead of string keys. Blazored.LocalStorage First I explain how to use local storage in Blazor. I assume you already have a blazor project setup. Install the Blazored.LocalStorage package with using NuGet. This can be done using the command in the Visual Studio package manager: Install-Package Blazored.LocalStorage Then in the 'Startup.cs' file add the following line to 'ConfigureServices' to make the LocalStorage service available through dependency injection: services.AddBlazoredLocalStorage(); Now you are ready to use local storage on your pages. To import the namespace on all pages you can add the following line to '_Imports.razor': @using Blazored.LocalStorage Now wi

Email Aliases Free with your Domain - Avoiding the costs of Private Email Accounts!

Throughout this article, I'll use Google Domains as an example registrar. However, this may also work with other registrars like Namecheap.  For anyone who hasn't heard of Google Domains, it was released in 2015, isn't normally the cheapest domain registrar. But, it has gained a reputation for being transparent and reliable with crystal clear costs. I purchased jam-es.com on Google Domains last year. It costs me just £10 a year to renew. Yes, I might have been able to save a few £s with Namecheap or Godaddy, but in the long run the renewal costs are pretty much the same. Google Domains comes with some interesting benefits. "Privacy guard" protection is provided with all domains and it has great Google Blogger and Google Sites integration with easy to edit DNS. But, the benefit I appreciate the most is email forwarding and 30 free alias'. I have a few different sites for different purposes, which are subdomains of jam-es.com. So the question I'll an
