C# Could not load file or assembly 'Microsoft.SharePoint.Library'

Question

I am developing on a 64bit version of Windows 7, running MOSS (SharePoint), this is my dev machine.

Now when I deploy my web service app to a test server Windows 2003 32bit (no Sharepoint installed) I get this error.

Could not load file or assembly 'Microsoft.SharePoint.Library, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' or one of its dependencies. The system cannot find the file specified

The DLL has clearly been copied to the bin directory (Microsoft.Sharepoint.dll).

Any ideas?

Answer 1

If you are using sharepoint dll's it will only work on a machine with sharepoint installed.

Even if you managed to hack it and get it to work, you would probably be breaking a license agreement.

Answer 2

There is a way to load Sharepoint libraries in a development console with windows XP, Vista or Seven.

See here: http://fernandof.wordpress.com/2008/02/11/how-to-install-the-sharepoint-2007-vs-2005-extensions-on-a-workstation/

[O]pen the regedit and create the following keys and the string value:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Web Server Extensions\12.0]

"Sharepoint"="Installed"

That’s it! You have fooled the installer into running on a workstation. Easy. I also recommend adding the core SharePoint assemblies into the [GAC] using gacutil. Those assemblies can be found by default in any [SharePoint] machine under the folder: C:\Program Files\Common Files\Microsoft Shared\web server extensions\12\ISAPI.
