.NET - Create and Run a Simple 'Hello World' Web App
With the .NET CLI you can create a new project with the dotnet new <TEMPLATE> command, where the TEMPLATE is the type of application you want to create. To create a .NET Web App execute the command dotnet new web --name <NAME>, the NAME parameter sets the name of the .NET project and directory created, if omitted the name of the current directory is used.
The web template creates a simple Hello World .NET starter web application that contains some basic configuration and a single endpoint that returns the string "Hello World!" from the base path ("/").
Follow these steps to create a starter .NET web application named MyWebApp and open it in VS Code.
- Install the .NET SDK from https://dotnet.microsoft.com/download, includes the .NET runtime and CLI
- Run the command
dotnet new web --name MyWebAppto create a new web app named MyWebApp - Navigate into the web app directory with the command
cd MyWebApp - Start the .NET web app with the command
dotnet run - Open the web app in a browser using the URL from the command output (Now listening on: http://localhost:[PORT NUMBER])
