Hi Matt,
We plan to add the examples of custom pages later. Currently, please use the existing plugins to copy source code. PlgMain plugin implements table views that retrieve current, historical data and events using Java Script API.
There is no recent changes in custom pages.
“Blazor is a feature of ASP.NET for building interactive web UIs using C# instead of JavaScript” So it’s a client feature.
We don’t plan to use it because we afraid it could be “Silverlight II”.
