I have two project who reference to the same path of:

Microsoft.Practices.EnterpriseLibrary.Data.dll

I use 

Database database = DatabaseFactory.CreateDatabase();

one project compiles OK and the other shows error:

Error 1 The type
‘Microsoft.Practices.EnterpriseLibrary.Common.Instrumentation.IInstrumentationEventProvider’
is defined in an assembly that is not referenced. You must add a
reference to assembly ‘Microsoft.Practices.EnterpriseLibrary.Common,
Version=4.0.0.0, Culture=neutral, PublicKeyToken=null’. <—in file
line.. –> 58 17 ControlPanel.Toolbar

Why might I get this error?

    Did you try adding the reference to Microsoft.Practices.EnterpriseLibrary.Common.dll to the project with the problem? Is it referenced in the other one with no problems?
