I am new to ASP.NET, VB.NET, SQL Server and i have to develop an online web application for our 25 Depots across the country. App will be basically Inventory cum Invoicing Software with some MIS reports. I want to use any easy/free tools which can make my life easy.
I have downloaded Iron Speed Designer which looks good but its not free.
Please advise any free/open source tool which i can use.
