Dapper.CustomTypeHandlers 
Dapper custom type handlers to serialize/deserialize objects to Xml and Json. Can be also used to map GUID to a string.
Installation
Use NuGet Package Manager

or .NET CLI
dotnet add package Dapper.CustomTypeHandlers
or just copy into the project file to reference the package
<PackageReference Include="Dapper.CustomTypeHandlers" Version="2.3.0" />
How to use
- Create class that implements IXmlObjectType or IJsonObjectType interface
public class Book
{
public long Id { get; set; }
public string Title { get; set; }
public BookDescription Description { get; set; }
}
public class BookDescription : IXmlObjectType
{
public Learn Learn { get; set; }
public string About { get; set; }
public Features Features { get; set; }
}
public class Learn
{
public List<string> Points { get; set; }
}
public class Features
{
public List<string> Points { get; set; }
}
- Register these new classes in Startup.cs
services.RegisterDapperCustomTypeHandlers(typeof(Book).Assembly);
- Create table in a database that contains a column of the XML type (SQL Server)
CREATE TABLE [dbo].[Books](
[Id] bigint IDENTITY(1,1) NOT NULL,
[Title] nvarchar(200) NOT NULL,
[Description] xml NULL
CONSTRAINT [PK_Books] PRIMARY KEY CLUSTERED
(
[Id] ASC
)
)
To persist object as a JSON, you can use the nvarchar field (class should implement IJsonObjectType)
CREATE TABLE [dbo].[Books](
[Id] bigint IDENTITY(1,1) NOT NULL,
[Title] nvarchar(200) NOT NULL,
[Description] nvarchar(max) NULL
CONSTRAINT [PK_Books] PRIMARY KEY CLUSTERED
(
[Id] ASC
)
)
- Use Dapper to save object data in the database
public async Task SaveBook(Book book)
{
using (var conn = _connectionFactory.Connection())
{
await conn.ExecuteAsync(_@"INSERT INTO Books (Title, Description) VALUES (@Title, @Description)", book);
}
}
