Welcome to the Official Visual Studio 2008 C# Samples

Language Samples

We have created a set of language samples to help you get familiar with  various C# language features.


LINQ Samples
We have created four sets of samples for you that are designed to help you  learn LINQ quickly, and to act as a reference and guide for those with more  advanced skills. A few handy utilities are also included.

LINQ Samples Database Connectivity Issue

The default connect string for the samples should work without modification  if you have SQL Server Express installed on your development machine. Here is an  alternate connect string that you can modify for your own purposes if you are  not using SQL Express but have SQL Server available. You will probably need to  modify the word test wherever it appears in the sample connect string.

string connString = "server=test;database=northwind;user id=test;password=test"

On some SQL Express installations, you may not have the rights to start a  user instance. If you get an error message to that effect, try removing the  clause ";user instance = true" from the connection string.
Be sure that the copies of the northwind database that you are accessing are  not marked read only. If necessary, browse to the copy of NORTHWIND.MDF you are  trying to access, right click on the file, choose properties. Clear the Read-only attribute.
On some slow machines, or when using a virtual pc, users have reported that  some database applications give errors the first time they run. Try running the  sample two or three times.
The customized copies of the Northwind database included with the samples  ship without an LDF (log) file. This is done intentionally, so that the LDF and  MDF files do not get out of sync. When you run a sample that uses the database,  or attach to the database from the Server Explorer inside Visual Studio, the LDF  file will be created automatically. You may have trouble connecting to the MDF  file if you are using the SQL Server Management Studio without first creating a  log file.
