The LINQ to SharePoint implementation promised in Bart de Smet's Coming soon - The return of IQueryable
Here from Bart's blog are its featured highlights:
- Supports writing LINQ queries for SharePoint lists in both C# 3.0 and Visual Basic 9.0
- The SpMetal entity type creation tool supports both C# 3.0 and Visual Basic 9.0
- Talks to SharePoint over web services or though the SharePoint Object Model
- Most CAML query constructs are available via LINQ
Bart promises to update the alpha to Orcas Beta 1 shortly. Check the B# blog or here for availability.
Querying SharePoint with a Web services and supporting updates in the obscure XML dialect called Collaborative Application Markup Language (CAML) isn't a piece of cake, as I demonstrated in a December 2003 Visual Studio Magazine article, "Manage SharePoint Lists."
P.S. Thanks for supporting VB and C#, Bart.
The .NET Standard Query Operators (SQOs) from LINQ Update
Bart released an April 6, 2007 update to the 0.9 Release Candidate for A custom implementation of the .NET Standard Query Operators from LINQ on CodePlex. This version is intended for use with VS2005 or Orcas March 2007 CTP. The custom SQOs implement a clone of the LINQ to Objects API (the System.Linq.Enumerable class).
After you build the project, you can add a reference to BdsSoft.Linq.dll in a test project and then replace using System.Linq; with using BdsSoft.Linq; to work with the custom implementation.
Note: If you uncomment the CS30 definition to use C# 3.0 features, you'll need to add a reference to the System.Core namespace to build the BdsSoft.Query class.
