Unable to generate an explicit migration because the following explicit migrations are pending
After renaming the namespace of some POCO classes from Primo.LicenseManager.Models to Primo.Licensing.DataModel, the Entity Framework scaffolding no longer recognizes the applied migrations:
Add-Migration -Name AddInvoiceEntity -Verbose -StartUpProjectName LicensingDataModel -ProjectName LicensingDataModel
Unable to generate an explicit migration because the following explicit migrations are pending: [201310191546582_CreateTables].
Apply the pending explicit migrations before attempting to generate a new explicit migration.
In SQL Server Management Studio:
select *
from __MigrationHistory
where MigrationId = '201310191546582_CreateTables'
MigrationId: 201310191546582_CreateTables
ContextKey: Primo.LicenseManager.Models.Migrations.Configuration
Model: 0x1F8B08000000....
ProductVersion: 5.0.0.net45
The problem
In the database, the ContextKey in the __MigrationHistory table is still the old namespace: Primo.LicenseManager.Models.Migrations.Configuration.
The solution
Update the ContextKey to the new namespace Primo.Licensing.DataModel.Migrations.Configuration
update __MigrationHistory
set ContextKey = 'Primo.Licensing.DataModel.Migrations.Configuration'
where MigrationId = '201310191546582_CreateTables'
Now this works:
