Referring to Code in IBM.Data.DB2 makes that Assembly Unavailable to the rest of my Solution

I have a C# console application with three assemblies: Main, Common and Utilities.

In a file in the Main assembly, Main.cs, I have the line:

using Utilities;

In a directory within the Common assembly, I have the DLL IBM.Data.DB2.dll.

In the Utilities assembly, I have a source module which accesses said dll. Utilities have a Reference to IBM.Data.DB2. In a source file within this assembly, Util.cs, I have the line:

using IBM.Data.DB2;

If, within a method in this file, I make any reference to code within the DB2 assembly, as in:

DbConnection c = new DB2Connection( _connectString );

I get an error compiling the Main assembly stating that the namespace name Utilities can not be found. Utilities compiles fine with or without the line. If I comment out the above line, everything compiles fine.

A helpful colleague came by and solved this for me in about five seconds.

Turns out that by default, when a new Console app is created in VS 2010, it gets a target framework of ".NET Framework 4 Client Profile". Changing this to ".NET Framework 4" made the problem go away.
