Camlex and Camlex.Client 5.4.2 released

New version 5.4.2 of Camlex library has been released. Starting with this version it became possible to generate CAML queries with string operators BeginsWith and Contains for ContentTypeId field type e.g. the following C# code:

Camlex.Query().Where(x => ((DataTypes.ContentTypeId)x["ContentTypeId"]).StartsWith("0x123")).ToString(true);

will generate the following CAML query:

<Query>
  <Where>
    <BeginsWith>
      <FieldRef Name="ContentTypeId" />
      <Value Type="ContentTypeId">0x123</Value>
    </BeginsWith>
  </Where>
</Query>

This is useful since when you add some site content type to SharePoint list under the hood SharePoint creates inherited content type (which has ContentTypeId which starts with ContentTypeId of parent site content type with appended 00 symbols and guid without dashes) and exactly this inherited content type is then used for list items created in this list. In order to fetch all items created with original site content type we may use CAML query with BeginsWith operator and ContentTypeIdof parent site content type.

As usual new version is available via Nuget.
