 "Learning about components, razor pages and binding was very useful and will be helpful in our implementation of Blazor replacing Silverlight. The templating and callbacks I also found particularly useful. The trainer was an expert in his knowledge and delivery. I really enjoyed being taught by him and his examples were very good at demonstrating the theory."
