LINQ to Active Directory implements a custom LINQ query provider that allows querying objects in Active Directory. Internally, queries are translated into LDAP filters which are sent to the server using the System.DirectoryServices .NET Framework library. LINQ stands for Language Integrated Query and is one of the core features of Microsoft's .NET Framework 3.5 release. More information can be found via the MSDN website on http://msdn.microsoft.com.

Features

* Translates into LDAP filters according to RFC 2254.
* Simple and approachable entity model with support of propagating updates back.
* Supports mappings to both the System.DirectoryServices (.NET) and ActiveDs (COM) APIs.
* Ships with a set of samples.

Continous LINQ is a .NET Framework 3.5 extension that builds on the LINQ query syntax to create continuous, self-updating result sets.
In traditional LINQ queries, you write your query and get stale results. With Continuous LINQ,

you write a query and the results of that query are continuously updated as changes are made to the source collection or items within the source collection.

CLINQ has tremendous value in GUI development and is especially useful in binding to filtered streams of data such as financial or other network message data.

Resource Page Description

Visual LINQ Query Builder is an add-in to Visual Studio 2008 Designer that helps you visually build LINQ to SQL queries. Functionally it provides the same experience as, for instance the Microsoft Access Query Builder, but in the LINQ domain. The entire UI of this add-in uses Windows Presentation Foundation. The goal of this tool is to help users become more familiar with the LINQ syntax. The tool may also demonstrate to users how to create their own Visual Studio 2008 add-in using Windows Presentation Foundation.

This academic project was developed by two students during an internship at Microsoft France, under the supervision of one of our Developer Evangelists. The project was in full collaboration with the STB International CPE team in Redmond.
