I'm currently experimenting with Blazor, a Microsoft Web Framework, and the other day I encountered a strange error that took me a while to figure out how to fix. When running the Blazor Server App, I received the System.NullReferenceException: 'Object reference not set to an instance of an object.' exception error in Visual Studio inside the generated _Host.cshtml file. The error didn't even show in the browser, it happened still in Visual Studio at Pages/_Host.cshtml at the following line: <component type="typeof(App)" render-mode="ServerPrerendered" /> Examining the exception in greater detail revealed that it happened at Pages__Host.ExecuteAsync() method, but this didn't help

VS Code is a popular, open-sourced lightweight code editor and in this post, we will create an empty JavaScript project using Visual Studio Code and it can be used as a basis for building more complex web apps. An HTML page, a JavaScript file, and a CSS stylesheet will be used to create the final web page. We will then copy a code from the CodePen example to make the web
