I have been trying to work my way on the Blazor "complete app" tutorial.
It took me quite some time to understand that in the section
there are separate instructions for both the "Server Side" blazor project and the "Client Side" blazor project.
From the documentation, it seems that you're asking us to change some files on the client-side part of the project and some others on the server host application.
It is very unclear that is one way OR the other and not both. The only way I figured it out is because I got fed up of trying to understand what you were suggesting and went to see the finished project in github.. which by the way points JUST to the server side version here
I was curious to see what was on the "Radzen-examples" root repository and noticed by pure chance that there was a BlazorCRMWasm folder .. and by looking at the folder structure I understood what was going on .. (that you are mixing the two project versions on a single tutorial).
I couldn't find references to the BlazorCRMWasm repository in the documentation and it was very difficult to follow afterward.
