We recently updated the #CodeFactory WebForms2Blazor automation templates and guidance/documentation over on GitHub. Check it out!
https://github.com/CodeFactoryLLC/WebForms2BlazorServer
This project is an implementation of a CodeFactory automation template designed specifically to migrate an existing legacy .NET Webforms application to a Blazor Server application. This template is offered as open-source and anyone can download and alter it to suit the particular needs of any WebForms migration efforts that they are faced with.
