When you want to implement a custom stsadm for SharePoint, all you realy have to do is implement the Microsoft.SharePoint.StsAdmin.ISPStsadmCommand interface. Because I develop on a machine with no SharePoint installed, I (only) copy the assemblies I need to develop locally. For the stsadm command I was working on recently (more on this in a future post) I only needed the Microsoft.SharePoint and Microsoft.Office.Server assemblies. Or at least I thought so…
After implementing the functionality I tried running code analysis, and I got two errors:
CA0052 : No targets were selected.
CA0055 : Could not load AssemblyName.
After trying several ways to fix this, I finally compiled the project on a machine with SharePoint installed. At that point, compiling and running code analysis both worked fine. Code analysis then gave a warning that pointed me to the solution of the problem:
CA2123 : Microsoft.Security : Add the following security attribute to ‘ClassName.MethodName(string)’ in order to match a LinkDemand on base method ‘ISPStsadmCommand.GetHelpMessage(string)': [SharePointPermission(SecurityAction.LinkDemand, ObjectModel = true)].
Apparently the attribute requires an extra reference. When I copied that assembly (Microsoft.SharePoint.Security) to my non-SharePoint development machine, all worked correctly. FYI: I did add the attribute code analysis suggested by the way.
