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

After installing the Office PIA (primary interop assemblies), add a reference to your project -> its on the .NET tab - component name "Office"

Answer 2

Have you actually gone to your references and added a .NET reference to the 'Microsoft.Office.Core' library? If you downloaded the example application, the answer would be yes. If that is the case, follow the advice in the article:

If your system does not have Microsoft Office Outlook 2003 you may have to change the References used by the "OutlookConnector" project. That is to say, if you received a build error described as "The type of namespace name 'Outlook' could not be found", you probably don't have Office 2003. Simply expand the project references, remove the afflicted items, and add the COM Library appropriate for your system. If someone has a dynamic way to handle this, I'd be curious to see you've done.

That should solve your problem. If not, let us know.

If you are not able to find PIA for Office 2013 then follow these steps:

1. Click on Solution Explorer in Visual Studio
2. Right click on your project name (not solution name)
3. Select 'Manage Nuget packages'
4. Click on Browse and search for PIA 2013, choose the shown PIA and click on Install.....

And you are done.

Answer 4

Now there is a nuget package for that.

https://www.nuget.org/packages/NetOffice.Core.Net40/

First I didn't find office in COM, so tried this nuget and it worked!

Answer 5

None of the above answer helped me, i was using Visual Studio 2017. What I did is, installed Office/SharePoint Development using Visual Studio Installer.

After that, I was able to see 'office', this assembly contains Microsoft.Office.Core.

Hope this helps you.

Open the properties of the solution and click publish. Then, reclick application files. Change prerequisite to include.
