Shmapper is a lightweight mapper for Sharepoint lists (2010 and 2013) for CSOM.
Maps ListItem fields to strongly typed entities and provides handy interface to work with them.
Wiki: Mapping How-to / Comparison with alternatives / CSOM Info

• Attribute-based mapper for POCO entities
• All basic CRUD operations for collections and single entities
• Supports LINQ-filters for entities

• Loads only mapped fields
• LINQ queries converted to CAML (by Camlex.Net)
• ExecuteQuery() called few times as possible

var SharepointClient = new SharepointClient("sharepoint-url", new NetworkCredential("user", "password"));
var CustomersByQuery = SharepointClient.Query<SpCustomer>(c => c.Title == "Cisco");
// Mapping:
[SharepointList("CustomersListName")]
public class SpCustomer : ISharepointItem
{
 [SharepointField("IdInternalName")]
 public int Id { get; set; }
 [SharepointField("TitleInternalName")]
 public string Title { get; set; }
}

All requests will be translated to CAML query.
For example, expression SharepointClient.Query(c => c.Title == "Cisco") will be translated to:

<!-- Produced CAML query -->
<View>
	<Query>
		<Where>
			<Eq>
				<FieldRef Name="TitleInternalName" />
				<Value Type="Text">Cisco</Value>
			</Eq>
		</Where>
	</Query>
	<ViewFields>
		<FieldRef Name="IdInternalName" />
		<FieldRef Name="TitleInternalName" />
	</ViewFields>
</View>

• Check exotic fields (system, non writable, etc)
• Support more field types
• More documentation
• Test with Sharepoint 2016
• Check mapping method (?)
• Exception handling (?)
