As reported in the previous chapters, it will be necessary to have the .NET 6 development framework available; you will also need to use .NET tools to run an in-memory web server.
To validate the functionality of cross-origin resource sharing (CORS), we should exploit a frontend application residing on a different HTTP address from the one where we will host the API.
To test the CORS example that we will propose within the chapter, we will take advantage of a web server in memory, which will allow us to host a simple static HTML page.
dotnet tool install -g LiveReloadServer
