Ask a question

if i counldn't use 'Add-Migration' and then do migrating, is there any way to generate a sqlite db file and table structure in phone app?

Build succeeded.
Startup project 'todomaui' targets platform 'Android'. The Entity Framework Core Package Manager Console Tools don't support this platform. See https://aka.ms/efcore-docs-pmc-tfms for more information.
