SQLite to .NET type mapping

Type mapping rules from this table are used when generating a model from a database with Entity Data Model Wizard in Visual Studio 2008 - 2023 and Create Model Wizard in Entity Developer.

SQLite data types	SSDL1	CSDL1	.NET
boolean	boolean	Boolean	System.Boolean
tinyint	tinyint	Byte	System.Byte
smallint, int16	smallint	Int32	System.Int16
int, int32	int32	Int32	System.Int32
INTEGER, int64	integer	Int64	System.Int64
REAL	real	Double	System.Double
NUMERIC, decimal, money, currency	numeric, decimal, money, currency	Decimal	System.Decimal
date, time, datetime, smalldate	date, time, datetime, smalldate	DateTime	System.DateTime
datetimeoffset	datetimeoffset	DateTimeOffset	System.DateTimeOffset
time	time	Time	System.TimeSpan
TEXT, ntext, char, nchar, varchar, nvarchar, string	text, ntext, char, nchar, varchar, nvarchar, string	String	System.String
BLOB, binary, varbinary, image, general	blob, binary, varbinary, image, general	Binary	System.Byte[]
guid	guid	Guid	System.Guid

¹ Note that when mapping corresponding database data type, you will need the .NET type with larger precision. That is because, for example, any Int32 value can be stored in the NUMBER(10) column, but largest NUMBER(10) column value cannot be stored in the Int32 field, it requires Int64 field.

DateTimeOffset type is not supported.
