[AccessD] Microsoft Visual Studio - How Difficult to Surround ?

All,

There is a good chance that I may be asked to support a website that was
built with Visual Studio.

I have never worked with this environment.

For the past five years I have primarily worked with Access, VBA, etc.

In a prior life, I worked with COBOL, Assembler, Easytrieve, JCL, SUPRA,
DB2 etc.  - therefore some slight brain damage  :-) 

I would like to know how difficult the transition is from Access and VBA
to Visual Studio.  

Thanks,
Brad
