What version of VB to use

[Mays]

I have a Microsoft Access 2013 App I will be converting to VB using Visual Studio Community 2015.

Should I use Windows Forms Application or WPF Application and why?

Below is a little about my project:

I have some forms that do various standard database manipulations in SQL Server tables and also I need to query a web site and pass it some variables in the URL address and receive a text response back from the web site. The web site will also upload and download .cvs files. I also have a need to have the user pick a file using the windows file selector

Given the above description what should I use? Also are there any free converters that will convert any of my Access things (forms and/or code) into the target VB?

Your title question asks which version of VB to use but then your post asks nothing of the sort.
You also asked your question in a VB6 section but you say you are using VB.Net so this is not VB6 related at all.

Personally I would use Windows Forms but that is largely because that is what I am comfortable with.

No there is no converter to convert Access forms and VBA macros to VB.Net application code.
