Error: type or namespace name could not be found

[ptcoder]

Hello all. I am getting this error when I attempt a build of my Visual Studio 2008 project. The build works fine on another computer, but not on this one. It appears there is some sort of reference missing, but I have no idea where to even look. All the references look the same on the two machines, but I don't know what to look for regarding data context references.

Here is the complete error message:

The type or namespace name 'MyDataContext' could not be found (are you missing a using directive or an assembly reference?)

Here is the beginning of my Class that throws the error:

public partial class alerts : System.Web.UI.Page
{
MyDataContext mydata = new MyIntouchDataContext();

Also, intellisense recognizes the MyDataContext so not sure why it is erroring on this. I actually have the same build error on all of my data context references throughout the project. I am just showing this one because they are all the same (just different name).

What should I be looking for? Has anyone experienced this issue?

Thanks for your assistance!

That MyDataContext looks 3rd party to me. Are you using a DLL or class that you haven't added a reference to?

It is a class. It was auto generated from a DBML file. The class is in the DESIGNER file and the designer file was created after saving the DBML. I am using Linq to SQL. The app still works, I just get those build errors and can't get a new build until those errors are gone. It almost seems like it's not truly an error since the app still works, but I am not that familiar with .NET to speak to that.

Thanks for your help!
