Provider instance, which uses mapping attributes from Microsoft.SqlServer.Server assembly. Used with Microsoft.Data.SqlClient provider starting from v5. Could be null of assembly not found.

public static IMetadataReader? MicrosoftSqlServerServerProvider

Methods

GetAttributes(Type)

Gets all mapping attributes on specified type.

public MappingAttribute[] GetAttributes(Type type)

Parameters

type Type

Attributes owner type.

Returns

MappingAttribute[]

Array of mapping attributes.

GetAttributes(Type, MemberInfo)

Gets all mapping attributes on specified type member.

public MappingAttribute[] GetAttributes(Type type, MemberInfo memberInfo)

Parameters

type Type

Member type. Could be used by some metadata providers to identify actual member owner type.

memberInfo MemberInfo

Type member for which mapping attributes should be returned.

Returns

MappingAttribute[]

Array of attributes.

GetDynamicColumns(Type)

Gets the dynamic columns defined on given type.

public MemberInfo[] GetDynamicColumns(Type type)

Parameters

type Type

The type.

Returns

MemberInfo[]

All dynamic columns defined on given type.

GetObjectID()

Should return a unique ID for cache purposes. If the implemented Metadata reader returns instance-specific data you'll need to calculate a unique value based on content. Otherwise just use a static const e.g. $".{nameof(YourMetadataReader)}."

public string GetObjectID()

Returns

string

The object ID as string
