Hi
Have a question about DLinq.
The example code floating around looks like this:
Northwind db = new Northwind(@"C:\...\northwnd.mdf");
var custs = from c in db.Customers where c.City == "London" select c;
How does this work. Will it retreive all the rows from the Customer table

I have the following queries/Observations about DLINQ.
1. I could not find any direct way of handling many to many relations.
Suppose if User and Role are related by a join table UserRole then I should
be able to have a collection of Roles in User and vice versa. Which i think
is not possible in DLINQ. (Please correct me if I am wrong)
2. State management is handle outside entities. In scenareos where a client
grabs a entity from a...

Hi
I'm hoping somebody can help me with the following problem that has occurred
to me.
Suppose I have two tables in an SQL Server database. Let's call these tables
A and B. Assume that A has two fields: a primary key and another holding a
string. In table B there are three fields: a primary key, a foreign key
(which links to the primary key in A) and other field holding a string.

I've downloaded the DLINQ samples from Microsoft and have always been
able to compile these in VS.NET 2005 Pro. I have a new project that I
added DLINQ references to and put in a simlpe query. It didn't
compile. I went back to the SampleQueries.sln, compiled and for the
first time it failed. It keeps looking at the query code as if it were
regular c#. It's wanting ";", which the queries don't use. Same thing
is occuring in my other...

In an application I am writing the user can define a series of
steps to be followed. I save them in a sql database using the
field "order" (a smallint) as the primary key.
(there are in the range of 20 steps)
On the admin page the steps are listed, in "order" order and the
user can create new steps and assign an order and all is well.
The problem may come in using a renumber function which should
take the steps in their current order...

How to fix ?
Write it the way that you know works... (i.e. the one you commented
out), or write that parses the input string doing a Split on '.', and
uses reflection to navigate the child hierarchy. Which isn't something I
have time to do right now...
