Parameters

propertyBuilder: IConventionPropertyBuilder

The builder for the property being configured.

stored: Nullable<Boolean>

If true, the computed value is calculated on row modification and stored in the database like a regular column. If false, the value is computed when the value is read, and does not occupy any actual storage. null selects the database provider default.

fromDataAnnotation: Boolean
