Definitive Guide for VB.NET developers coming from VB World
For VB.NET developers coming from VB World, I would really and strongly recommend the following book "Upgrading Microsoft Visual Basic 6.0 to Microsoft Visual Basic .NET w/accompanying CD-ROM".
The book has an elegant coverage on the differences between the two world, seamless migration path, redesign related issues and points to be taken care with respect to the COM component.
You may also like to check out the free download of the eBook that ew discussed sometime back over here.
Check out Amazon page of ordering the book here.
