How to use Visual webpart in SharePoint 2010 in Sandbox Solution

sharepointsharepoint-2010sharepoint-deployment

I am trying to use a Visual Webpart in a sandbox solution. However every I deploy it: it gives me the following error:

Error 1 The deployment type "TemplateFile" of file "VisualWebPart1UserControl.ascx" in Project Item "VisualWebPart1" is not compatible with a Feature in a Sandboxed Solution.

I did some research and found out that Visual WP is not supported in Sandbox solutions. Is there anyway I can have Visual WP in a sandbox solution?

And is there any specific reason as to why Visual WP is not really supported in Sandbox solution.

Use VS Sharepoint Power Tools. It has Visual Web Part item template for sandbox solutions. http://visualstudiogallery.msdn.microsoft.com/8e602a8c-6714-4549-9e95-f3700344b0d9/

The problem is that Interop.ActiveDs.dll does not allow partially trusted callers. Your best bet is to deploy a signed interop assembly to the GAC:

TlbImp %windir%\system32\ActiveDs.tlb /out:Interop.ActiveDs.dll /keyfile:KeyFile.snk

Sharepoint 2010 sandboxed solution

I fixed thus by going to Central Administration > System Settings > Manager user solutions. Under Load Balancing, I selected "All Sandboxed code runs on the same machine as a request" option and it is all working now.

For some reason I am still missing this service - "Microsoft SharePoint Foundation User Code Service". However I have always had "Microsoft SharePoint Foundation Sandboxed Code Service" service listed under Services on central administration site. And I am using SharePoint Server Standard Edition so it may be that for Standard edition I have this service instead.
