I am getting an error message when I create my Crystal Report and build the project. The error message is:

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

I have seen some responses that Targeted Framework should be
".net Framework 4 client profile", but that did not solve the problem.

I am using Visual Studio 2010 with Crystal Reports built in menu option and I have the following references in my project:

C#

using CrystalDecisions.Shared;
using CrystalDecisions.ReportSource;
using CrystalDecisions.CrystalReports.Engine;

The code with the using statements is built for me when I create the .rpt file, so I don't know why it is having a problem.

Does anyone know why this is happening?

Solution 3

I had the same problem and this is what I did. I went to the properties of my project and chose .NET Framework 4 as the target Framework instead of .NET Framework 4 Client Profile. I rebuild my project afterwards and it worked.
