Throwing my hat in saying I agree with you. There are certainly aspects of Blazor that need to be improved, though. Sometimes Intellisense has an aneurism and syntax highlighting completely breaks. Debugging needs some TLC in instances where exceptions are thrown in the JS console instead of being caught by the VS debugger.

I have experienced _some_ performance problems, but only when I don't have enough resources for VS to gobble up. Should it be lighter? Absolutely. It's not like I can't get work done though.
