❔ Can't run Add-migration to create my local database.

I have an web api and some .net standard class library that holds my entities but whenever i run "Add-migration" on the .net standard library i get a runtime issue I'm missing a startup file with corresponding framework. So I checked the references between the different class libraries and saw that i have a project reference to the .net standard class library but when i run "Add-migration" i get the following message

Build started...

Specify --help for a list of available options and commands.
Unrecognized command or argument 'add-migration'.

HerculesOP•2y ago

yes it is. as you can see in the image that what i'm writing

SG97•2y ago

? in your image I see dotnet ef add-migration MyFirstMigration

HerculesOP•2y ago

the name of my firstmigration would be "MyFirstMigration" I believe you create the migrations after running update-database https://www.entityframeworktutorial.net/efcore/entity-framework-core-migration.aspx Under Adding a Migration

but the syntax is wrong you can see both (PM and .net cli versions) on that article

Yes, syntax is wrong. You use dotnet ef add migration <args> for regular terminal and Add-Migration <args> for the Package Manager Console So no dash in the first one

HerculesOP•2y ago

you're right, this should resolve my issue- I shouldn't use the dashes on CLI just as @FusedQyou explained too.
