Creation of the template

The template was created using the ASP.NET Core Web App project template from Microsoft 12/2023, with .NET 6.0 framework. LightningChart JS dependency was added using libman.json with following configuration to download the library from jsdelivr.com:

{
  "version": "1.0",
  "defaultProvider": "cdnjs",
  "libraries": [
    {
      "library": "@lightningchart/[email protected]",
      "destination": "wwwroot/lib/lcjs",
      "provider": "jsdelivr"
    }
  ]
}

All other changes, such as creating the example application, using LCJS library and using SignalR have been isolated into one convenient Git commit which you can view HERE.
