针对SQL Server时，为键属性配置值生成策略。

public static Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionPropertyBuilder HasValueGenerationStrategy (this Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionPropertyBuilder propertyBuilder, Microsoft.EntityFrameworkCore.Metadata.SqlServerValueGenerationStrategy? valueGenerationStrategy, bool fromDataAnnotation = false);

public static Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionPropertyBuilder? HasValueGenerationStrategy (this Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionPropertyBuilder propertyBuilder, Microsoft.EntityFrameworkCore.Metadata.SqlServerValueGenerationStrategy? valueGenerationStrategy, bool fromDataAnnotation = false);

static member HasValueGenerationStrategy : Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionPropertyBuilder * Nullable<Microsoft.EntityFrameworkCore.Metadata.SqlServerValueGenerationStrategy> * bool -> Microsoft.EntityFrameworkCore.Metadata.Builders.IConventionPropertyBuilder

<Extension()>
Public Function HasValueGenerationStrategy (propertyBuilder As IConventionPropertyBuilder, valueGenerationStrategy As Nullable(Of SqlServerValueGenerationStrategy), Optional fromDataAnnotation As Boolean = false) As IConventionPropertyBuilder

参数

propertyBuilder: IConventionPropertyBuilder

要配置的属性的生成器。

valueGenerationStrategy: Nullable<SqlServerValueGenerationStrategy>

值生成策略。

fromDataAnnotation: Boolean

指示是否使用数据注释指定配置。

IConventionPropertyBuilder

如果应用了配置，则为同一生成器实例， null 否则为。
