I needed to make a console application using nettiers class libraries. I created a new Console Application project, added references to all the libraries from NetTiers and created an app.config file with all the necessary configurations. I get intellisense and no errors and everything when I am doing the coding, but when I go to compile the application, I'm getting an error that PPGEDI.Data doesn't exist.

I only have 1 line in the program.cs Main method:

PPGEDI.Entities.VansEntity van 
  = DataRepository.VansEntityProvider.GetById(16);

I'm getting the following error:

Error   93  
   The type or namespace name 'Data' 
   does not exist in the namespace 'PPGEDI' 
   (are you missing an assembly reference?)

It's frustrating, because I know I've added the assembly reference:

I'm using Visual Studio 2010, with C# and .NET 4.0. Can anyone give me an idea as to what I need to do to get this to work.

As a note, this works if I use the same statement in a method on an ASPX page in the web application generated by nettiers.

    are you using the .NET client profile in your console app by chance? If so switch to the full .NET 4 as target framework – BrokenGlass Aug 17 '11 at 19:44
  • Also, unless someone can confirm (I'm not familiar with these libraries), take a look at that assembly in your favorite IL decompiler (Reflector, ilSpy, etc.) and ensure that there *are* actually types in that namespace defined within that assembly. – Adam Robinson Aug 17 '11 at 19:46
  • .NET versions possible conflict? Did you try to make your project of .NET 2.0 or 3.5? – Tigran Aug 17 '11 at 20:03
  • @Adam Robinson It is actually in that namespace and class name. BrokenGlass: I am not using the .NET client profile as my framework, I am using the full .NET 4 – stephenbayer Aug 17 '11 at 20:04
  • @Tigran everything in the entire solution is using .NET 4.0. I have gone down all the class libraries and have verified this. – stephenbayer Aug 17 '11 at 20:05
  • @BrokenGlass, you were absolutely correct. I double checked and it was set to ".NET Framework Client Profile", I changed it to .NET 4 and it's working now, can you put that as an answer? – stephenbayer Aug 17 '11 at 20:12

@BrokenGlass, you were absolutely correct. I double checked and it was set to ".NET Framework Client Profile", I changed it to .NET 4 and it's working now, can you put that as an answer?

You are using the .NET client profile in your console app which is a "minified" version that doesn’t contain all assemblies.

The problem is that when your app adds a reference to a class library that is targeting the full framework, references to the "full" framework assembly will not resolve. This results in the rather non-forthcoming error message that you see. Switching to the the full .NET 4 as target framework will resolve the issue.

For a more in depth overview of the problem and the .NET 4 Client Profile in general also see "What’s new in .NET Framework 4 Client Profile RTM"
