Last year I wrote a post about building Microsoft Office SharePoint Server (MOSS) 2007 solutions on a Team Foundation Server (TFS) 2010 build server, which talked about copying various SharePoint assemblies to a "Reference Assemblies" folder and adding a corresponding registry key for MSBuild to locate the assemblies.

It's nice to see that a similar process has already been covered on MSDN for SharePoint 2010:

How to Build SharePoint Projects with TFS Team Build

However, there are few things I noticed about this MSDN article.

First, the path for the registry key on 64-bit systems is incorrect (although you should be able to easily figure out what the correct path is, once you are navigating down through the registry). For the record:

HKEY_LOCAL_SYSTEM\SOFTWARE\Microsoft\Wow6432Node\.NETFramework\v2.0.50727\AssemblyFoldersEx\SharePoint14]@="<AssemblyFolderLocation>"

should be:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v2.0.50727\AssemblyFoldersEx\SharePoint14]@="<AssemblyFolderLocation>"

Second, the MSDN article instructs you to copy several Visual Studio SharePoint assemblies to the GAC on the build server:

Copy the SharePoint Tool Assemblies and Files to the GAC
The following assemblies must be copied to the GAC of the build system:
  • Microsoft.VisualStudio.SharePoint.Designers.Models.dll
  • Microsoft.VisualStudio.SharePoint.Designers.Models.Features.dll
  • Microsoft.VisualStudio.SharePoint.Designers.Models.Packages.dll Microsoft.VisualStudio.SharePoint.dll

Since I chose to install Visual Studio 2010 on my build server (DAZZLER), then I shouldn't have to install any additional Visual Studio assemblies on my build server. Everything should just work. When I looked at the GAC on my SharePoint Server 2010 development VM (FOOBAR5), I didn't see these assemblies, and since FOOBAR5 doesn't have any trouble building SharePoint projects without these assemblies in the GAC, then I didn't expect DAZZLER would have any problems either.

Lastly, as I mentioned in my post last year regarding building MOSS 2007 solutions with TFS 2010, you'll probably want to copy more assemblies than those that are directly referenced in you project -- in order to avoid code analysis warnings, like the following:

CA0060 : The indirectly-referenced assembly 'Microsoft.SharePoint.Client.ServerRuntime, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' could not be found. This assembly is not required for analysis, however, analysis results could be incomplete. This assembly was referenced by: C:\Program Files\Reference Assemblies\Microsoft\SharePoint v4\Microsoft.SharePoint.dll.

Here are the assemblies that I ended up copying from FOOBAR5 (which has SharePoint Server 2010 installed) to DAZZLER (which does not have SharePoint Server 2010 installed):

Reference Assemblies for Building SharePoint 2010 Projects
AssemblySource Location on SharePoint 2010 Server
Microsoft.BusinessData.dll ISAPI
Microsoft.HtmlTrans.Interface.dll GAC_MSIL
Microsoft.IdentityModel.dll GAC_MSIL
Microsoft.Office.Server.dll ISAPI
Microsoft.Office.Server.UI.dll GAC_MSIL
Microsoft.Office.Server.UserProfiles.dll ISAPI
Microsoft.SharePoint.AdministrationOperation.dll GAC_MSIL
Microsoft.SharePoint.Client.ServerRuntime.dll GAC_MSIL
Microsoft.SharePoint.Diagnostics.dll GAC_MSIL
Microsoft.SharePoint.dll ISAPI
Microsoft.SharePoint.Dsp.dll GAC_MSIL
Microsoft.SharePoint.Library.dll GAC_MSIL
Microsoft.SharePoint.Powershell.dll GAC_MSIL
Microsoft.SharePoint.Publishing.dll ISAPI
Microsoft.SharePoint.Search.dll ISAPI
Microsoft.SharePoint.Security.dll ISAPI
Microsoft.SharePoint.Taxonomy.dll ISAPI
microsoft.sharepoint.WorkflowActions.dll ISAPI
Microsoft.Web.Administration.dll GAC_MSIL
Microsoft.Web.CommandUI.dll ISAPI
Microsoft.Web.Design.Server.dll GAC_MSIL

In case it's not immediately obvious, "ISAPI" in the above table means:

C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\ISAPI

...and "GAC_MSIL" indicates the corresponding assembly folder under C:\Windows\assembly\GAC_MSIL. For example:

C:\Windows\assembly\GAC_MSIL\Microsoft.BusinessData\14.0.0.0__71e9bce111e9429c

I may need to copy additional SharePoint assemblies to my build server in the future, but for now, these are sufficient to compile my current solutions without any warnings.

Update (2011-03-14)
I also recommend you remove extraneous SharePoint assemblies from your build output, as described in one of my later posts.
