This post shows how HTML header meta data can be dynamically updated or changed for a Blazor Web assembly application routes hosted in ASP.NET Core. This can be usually for changing how URL link previews are displayed when sharing links.

Updating the HTTP Header data to match the URL route used in the Blazor WASM can be supported using a Razor Page host file instead of using a static html file. The Razor Page _Host file can use code behind and a model from this class. The Model can the be used to display the different values as required. This is a Hosted WASM application using ASP.NET Core as the server.
