DLINQ & Remoting; LINQ over Active Directory

1. Does DLINQ supports remoting What will happen if I'll pass DLINQ entity out of application domain via remoting
2. I'm interested in using of LINQ to perform queries over active directory database. Any suggestion

Visual Studio 20084

Hi there,

I would suggest looking into DSML Services for Windows. It is a free Microsoft Web Service wrapper for Active Directories which allows for querying into/out of any Active Directory (including ADAM!) The input/output is the open-standard DSML language which is an XML form you could use with XLinq.

1. Does DLINQ supports remoting What will happen if I'll pass DLINQ entity out of application domain via remoting
Because LINQ to SQL entities support deferred loading each is indirectly linked to its ADO connection object. So general .Net remoting would necessarily fail. Remoting via XML serialization is supported, however.

2. I'm interested in using of LINQ to perform queries over active directory database. Any suggestion
The Active Directory team at Microsoft was looking into building 'LINQ over Active Directory'. No word yet on if this will become an actual product.

Is #2 available now . I am looking for a solution where LINQ can query over Active Directory.

As far as I'm aware, there won't be a LINQ for Active Directory when Visual Studio 'Orcas' ships.

Hi Jonathan,

I have vista ultimate and tried installing DSML.When i tried to configure DSML services it says "Can't connect to IIS, please check to make sure IIS is installed".I checked for IIS and have also set IIS 6.0 compatibility.

Any suggestions .Thanks for your help in advance.

Regards

Raj

Bart De Smet has an excellent series of articles on building an LDAP provider for LINQ, which you might find useful:

Of course, it's not production-quality (his words), but it's a great series on how one might go about creating a provider.
