Use VB6 dll in c#

Question

I have created VB6 Project of ActiveX dll type added two function

Public Function Name(aName As String)
MsgBox ("Your Name is " & aName)
End Function
Public Function TestName(aName As String) As String
TestName = " Hello " & aName
End Function

Created DLL from same Project.

 

Then created Wrapper using below command .

 

C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6.1 Tools>TlbImp.exe C:\Test\TestActiveX\Project1.dll /out: C:\Test\TestActiveX\out\Project1.dll

 

If i am performing only above operation then i am not getting Project1.dll under COM section but then i am registering dll using below code

 

C:\WINDOWS\system32>regsvr32 C:\Test\TestActiveX\Project1.dll

 

then only i am getting dll under COM section inside VisuaL studio Add Reference Dialog

 

i tried adding reference from C:\Test\TestActiveX\out\Project1.dll folder also but every time i am getting runtime error as below.

 

System.Runtime.InteropServices.COMException: 'Retrieving the COM class factory for component with CLSID {ID} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).'

public string ReturnFromCOM()
{
TestClass testClass = new TestClass();
return testClass.TestName(" Hello ");
}

i am not able to get it done, don't know what is missing in this steps. My Windows OS : 64 bit Windows 10 Framework 4.6.1 as well as 4.8.1 but created console application with Framework 4.6.1

 

i tried even changing project target to x64/x86/anyCPU but it's not working at all.
