# How do I add a COM tlb as a reference?

 zippy1981 May 23, 2013 at 12:20 AM If I add mscoree.tbl as a reference I get the following: § projects:\ConsoleApplication2\References>ls Interop.mscoree|select * SSItemMode : ~< PSPath : studioshell\PSDTE::solution\projects\ConsoleApplication2\References\Interop.mscoree PSParentPath : studioshell\PSDTE::solution\projects\ConsoleApplication2\References PSChildName : Interop.mscoree PSDrive : projects PSProvider : studioshell\PSDTE PSIsContainer : False SpecificVersion : True ContainingProject : CodeOwls.StudioShell.Paths.Items.ProjectModel.ShellProject Name : Interop.mscoree Type : prjReferenceTypeActiveX Identity : {5477469E-83B1-11D2-8B49-00A0C9B7C9C4}\2.4\0\tlbimp Path : c:\users\justin\documents\visual studio 2010\Projects\ConsoleApplication2\ConsoleApplication2\obj\x86\Debug\Interop.mscoree.dll Description : Common Language Runtime Execution Engine 2.4 Library Culture : 0 MajorVersion : 2 MinorVersion : 4 RevisionNumber : 0 BuildNumber : 0 StrongName : False SourceProject : CopyLocal : False PublicKeyToken : Version : 2.4.0.0 But I'm not sure how to New-Item that. beefarino Coordinator May 23, 2013 at 12:28 PM Two choices: 1) specify the type library guid as a string in the -name parameter, along with the major version number of the object in the -majorversion custom parameter for the references collection and an item -type of COM; optionally you can include a -minorversion number and a -locate identifier: new-item -path dte:\solution\projects\consoleapplication2\references -name '{5477469E-83B1-11D2-8B49-00A0C9B7C9C4}' -majorversion 2 -type com this method is difficult to use because you need to know the GUID for the type library beforehand. 2) specify the full path to the TLB, dll, ocx, etc file: new-item -path dte:\solution\projects\consoleapplication2\references -value c:\path\to\tlbfile.tlb Note that for COM interop wrappers, the first method is your only choice. zippy1981 May 25, 2013 at 5:52 PM For the second form I had to add -Type ActiveX like so New-Item -Path DTE:\Solution\Projects\ConsoleApplication1\References -value C:\Windows\Microsoft.NET\Framework64\v2.0.50727\mscoree.tlb -Type ActiveX Thanks!!! zippy1981 May 25, 2013 at 6:29 PM Two more things, Do you think there is a place in the documentation to list how to manipulate references to include this. do you think that belongs in about_StudioShell_Drives.help.txt or in another file?
