ef-core savechanges - invalid columnname

Hi,

I changed a database table (both updated and dropped and recreated the table).  Somehow, running the command in the package manager console:

Update-Database -context <contextname>

says that "No migrations were applied.  The database is already up to date."

So, I changed the context manually. 

When I execute context.savechanges(), it says "invalid column name 'column1'", but column1 does not exist in the current table.  It did exist in the previous version before I dropped and recreated the table.  'column1' is a foreign key - referencing another column.

I have not been able to establish this FK relationship in the context

entity.HasOne(d => d.TableNameForeignKeyReferenceTable)
.WithMany(p => p.TableName)
.HasForeignKey(d => d.foreignKeyColumn)
.OnDelete(DeleteBehavior.ClientSetNull)
.HasConstraintName("foreignkeyname");

thus,

entity.HasOne(d => d.PersonAliasPerson) /* compiler is not recognizing this */
.WithMany(p => p.PersonAlias)
.HasForeignKey(d => d.PersonId)
.OnDelete(DeleteBehavior.ClientSetNull)
.HasConstraintName("FK_PersonAlias_Person");

Table Structure
=============
Person
=============
PersonId
DL
SSN

PersonAlias
=============
PersonAliasId
PersonId
LastName
FirstName

Thank you
