Addin.dll does not contain any types that can be registered for COM Interop warning

Hi Everyone...

I am trying to register a .dll file in COM.But it is failing and warnings are coming:


C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets(935,9): warning MSB3391: "c:\users\acd92078.myttl\documents\visual studio 2010\Projects\SWADDIN_Test\SWADDIN_Test\bin\Debug\SWADDIN_Test.dll" does not contain any types that can be unregistered for COM Interop.

C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets(3341,9): warning MSB3214: "c:\users\acd92078.myttl\documents\visual studio 2010\Projects\SWADDIN_Test\SWADDIN_Test\bin\Debug\SWADDIN_Test.dll" does not contain any types that can be registered for COM Interop.


I have tried all the suggestions that were given previously in one of the discussions on similar error on PC review.


This is my Code:-


using System;

using System.Collections;

using System.Reflection;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using SolidWorks.Interop.sldworks;

using SolidWorks.Interop.swcommands;

using SolidWorks.Interop.swconst;

using SolidWorks.Interop.swpublished;

using SolidWorksTools;

using SolidWorksTools.File;

using System.Runtime.InteropServices;



using System.Diagnostics;


namespace SWADDIN_Test

{


[ComVisible(true)]

[Guid("6701cbb8-ee73-46ed-bbe5-8a80c9a0280b")]

[InterfaceType(ComInterfaceType.InterfaceIsIDispatch)]

interface ISWIntegration

{

void DoSWIntegration();

}//end of interface Dummy ISWIntegration


[Guid("6701cbb8-ee73-46ed-bbe5-8a80c9a0280b")]

[ClassInterface(ClassInterfaceType.AutoDual)]

[ProgId("SWADDIN_Test.SWIntegration")]

[ComVisible(true)]

public class SWIntegration : ISwAddin, ISWIntegration

{

public SldWorks mSWApplication;

private int mSWCookie;


public SWIntegration()

{ }//end of parametereless constructor


public void DoSWIntegration()

{ }//end of dummy method DoSWIntegration


public bool ConnectToSW(object ThisSW, int Cookie)

{

mSWApplication = (SldWorks)ThisSW;

mSWCookie = Cookie;

// Set-up add-in call back info

bool result = mSWApplication.SetAddinCallbackInfo(0, this, Cookie);

this.UISetup();

return true;

}//end of method ConnectToSW()


public bool DisconnectFromSW()

{

return UITeardown();

}//end of method DisconnectFromSW()


public void UISetup()

{ }//end of method UISetup()


public bool UITeardown()

{

return true;

}//end of method UITeardown()


[ComRegisterFunction()]//Attribute

private static void ComRegister(Type t)

{

string keyPath = String.Format(@"SOFTWARE\SolidWorks\AddIns\{0:b}", t.GUID);

using (Microsoft.Win32.RegistryKey rk = Microsoft.Win32.Registry.LocalMachine.CreateSubKey(keyPath))

{

rk.SetValue(null, 1);// Load at startup

rk.SetValue("Title", "Abhijit's SwAddin"); // Title

rk.SetValue("Description", "All your pixels now belong to us"); // Description

}//end of using statement

}//end of method ComRegister()


[ComUnregisterFunction()]//Attribute

private static void ComUnregister(Type t)

{

string keyPath = String.Format(@"SOFTWARE\SolidWorks\AddIns\{0:b}", t.GUID);

Microsoft.Win32.Registry.LocalMachine.DeleteSubKeyTree(keyPath);

}//end of method ComUnregister()


}//end of class SWIntegration

}//end of namespace SWADDIN_Test



Kindly suggest me a solution on this.
Thanks in advance.
