Microsoft.Office.Core Reference Missing

Question

Using the example provided in codeproject I am struggling to work out where I can find the reference to the library Microsoft.Office.Core.

I am getting the error "The referenced component 'Microsoft.Office.Core' could not be found."

I only have office 2007 enterprise edition and outlook 2003 installed on this system. Could this be the cause of this? Otherwise which specific dll am I supposed to be referencing?

Answer 1

If someone not have reference in .NET . COM (tab) or not have office installed on machine where visual was installed can do :

1. Download and install: Microsoft Office Developer Tools

2. Add references from:

   C:\Program Files (x86)\Microsoft Visual Studio 11.0\Visual Studio Tools for Office\PIA\Office15
   

Answer 2

You need to download and install the PIA (primary interop assemblies) for the version of Office you are using. Once installed you can then add a reference to your project and they will be available from the add reference dialog. Here are the links to download them...

Office 2010 PIA

Office 2007 PIA

Office 2003 PIA

I faced the same problem when i tried to open my old c# project into visual studio 2017 version. This problem arises typically when you try to open a project that you made with previous version of VS and open it with latest version. what i did is,i opened my project and delete the reference from my project,then added Microsoft outlook 12.0 object library and Microsoft office 12.0 object libraryMicrosoft outlook 12.0 object library

Answer 4

You can add reference of Microsoft.Office.Core from COM components tab in the add reference window by adding reference of Microsoft Office 12.0 Object Library. The screen shot will shows what component you need.

Answer 5

In case you are using Visual Studio 2012, for this to work and in order to make reference to Microsoft Office Core, you have to make the reference through Visual Studio by clicking on the top menu's Project, Add Reference, Extensions button and checking office which is now (14.0).

I have the same trouble. I went to Add references, COM tab, an select Microsoft Office 15.0 Objetct Library. Ok, and my problem ends.

part of my code is:

EXCEL.Range rango;
            rango = (EXCEL.Range)HojadetrabajoExcel.get_Range("AE13", "AK23");
            rango.Select();
      //      EXCEL.Pictures Lafoto = (EXCEL.Pictures).HojadetrabajoExcel.Pictures(System.Reflection.Missing.Value);
            EXCEL.Pictures Lafoto = HojadetrabajoExcel.Pictures(System.Reflection.Missing.Value);

            HojadetrabajoExcel.Shapes.AddPicture(@"D:\GENETICA HUMANA\Reportes\imagenes\" + Variables.nombreimagen,
                Microsoft.Office.Core.MsoTriState.msoFalse, Microsoft.Office.Core.MsoTriState.msoCTrue,
                float.Parse(rango.Left.ToString()),float.Parse(rango.Top.ToString()), float.Parse(rango.Width.ToString()),
                float.Parse(rango.Height.ToString()));
