HasDefaultValue(PropertyBuilder)

Configures the default value for the column that the property maps to when targeting a relational database.

public static Microsoft.EntityFrameworkCore.Metadata.Builders.PropertyBuilder HasDefaultValue (this Microsoft.EntityFrameworkCore.Metadata.Builders.PropertyBuilder propertyBuilder);

static member HasDefaultValue : Microsoft.EntityFrameworkCore.Metadata.Builders.PropertyBuilder -> Microsoft.EntityFrameworkCore.Metadata.Builders.PropertyBuilder

<Extension()>
Public Function HasDefaultValue (propertyBuilder As PropertyBuilder) As PropertyBuilder

Parameters

propertyBuilder

PropertyBuilder

The builder for the property being configured.

Returns

PropertyBuilder

The same builder instance so that multiple calls can be chained.

Remarks

When called with no argument, this method tells EF that a column has a default value constraint of some sort without needing to specify exactly what it is. This can be useful when mapping EF to an existing database.

See Database default values for more information and examples.
