.SYNOPSIS
|
|
Enables Code First Migrations in a project.
|
|
|

.DESCRIPTION
|
|
Enables Migrations by scaffolding a migrations configuration class in the project. If the
|
|
target database was created by an initializer, an initial migration will be created (unless
|
|
automatic migrations are enabled via the EnableAutomaticMigrations parameter).
|
|
|
|
.PARAMETER EnableAutomaticMigrations
|
|
Specifies whether automatic migrations will be enabled in the scaffolded migrations configuration.
|
|
If ommitted, automatic migrations will be disabled.
|
|
|
|
.PARAMETER ProjectName
|
|
Specifies the project that the scaffolded migrations configuration class will
|
|
be added to. If omitted, the default project selected in package manager
|
|
console is used.
|
|
|
|
.PARAMETER Force
|
|
Specifies that the migrations configuration be overwritten when running more
|
|
than once for a given project.
