Ive been dealing with this for a few days and Im driving crazy here. I created a uwp project that uses SQLite and EF Core to handle database layer and I had to add more columns to the entities I created at the beginning. I used Code-First approach and I was able to run my first migration (created the Migrations folder with the migration class and the snapshot). But when I try to run the 'Add-Migrations SecondMigration' command I get the following error.
PM> Add-Migration MigrationPk To undo this action, use Remove-Migration. Add-Migration : Cannot add the link because the source file '' cannot be found. At line:1 char:2 + Add-Migration MigrationPk + ~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : OperationStopped: (:) [Add-Migration], COMException + FullyQualifiedErrorId : System.Runtime.InteropServices.COMException,Add-Migration
I have installed the following:
"Microsoft.EntityFrameworkCore.Sqlite": "1.1.2", "Microsoft.EntityFrameworkCore.Tools": "1.1.1", "Microsoft.NETCore.UniversalWindowsPlatform": "5.2.2"
And I have the following project structure:
-UWP project (using PRISM framework) -DAL class library project -LogicUI class library (view models) -Utils class library project -Test projects
I also tried to run the 'Add-Migration' command by using the context, project, and startProject as described here: https://docs.microsoft.com/en-us/ef/core/miscellaneous/cli/powershell
I also uninstalled and installed again EF core without any luck
Any ideas? Thanks guys!
Looks like the issue was that I had the db name in a constant. When I moved away from there and "hardcoded" in the dbcontext the migrations started to work
