I'm using the MS sample (https://github.com/dotnet/blazor-samples) as it's about all I need to re-write reports for a legacy DB. I notice it seems to reload from the DB without interaction from me i.e. just opening the home page. It seems like it's going into home.razor a number of times (e.g. it hits my breakpoint on _lastPage initialization) causing it to query the DB each time. With the simple/local DB they use that's not much of a performance issue but with a real/remote DB it adds a lot of time.
So what's triggering the 'refresh' and can/should I avoid it?
