Thanks Sergey for our time. we are not planning to us DLLImport. Please find the below link, which explain how can we create a COM wrapper to call .NET Code in VB.

What we are planning is convert a part of project. Use the converted part with VB6. continue the same approach till the we migrate complete project. Once we are done remove the COM classes that we added to call the .NET code in VB.
This way in the end we will left only with .NET code. And complete VB6 code will be migrated.
Let me know your views on this.

Thanks RyanDev. We are rewriting the code. The plan is to do it in iterative way. We are planning to we will slice the application in piece and convert it piece by piece. We are using the COM classes to generate the wrapper on every piece that we have converted to .NET. Once we completed whole application we will remove the wrapper classes and the complete application will be migrated to .NET. Let me know your views.
