Hi Alper, I was replicating this in a new project for you but seems this new 3.3.2 fixed the issue
Initial-value problem seems to have dissapeared after i updated efcore tools from prev version 3.1.4 then it would still fail to generate the migration on the last step (angular project would get the info, classes also created in dotnetcore). It seems that if i manually add a migration (1 time) to the new project and apply it, i can then add entities from abp suite and it succeeds. Strange?
Fresh install of the abp cli and suite, generate solution from suite, open solution in vs2019 run db migrator project to create the db, add any entity with any props, the steps suceed from 1-8, step 9 the db migrator part fails as most of the related .cs documents end up placing %%initial-value%% next to the generated properties..
