Kind of applications that can be based on dotnet framework alone

i am intend to do a web application and host it. Since i have some knowledge in Asp.Netand C#, i decided to develop using DotNet.

I am not sure about the licencing from microsoft for dotnet.

My question is :

Is it possible to use only dotnet framework which is free and use MySql as backend 开发者_开发知识库to develop a webapplication and host it without buying licence ? If so what editor can i use to develop the application ?

Pls suggest me some ideas. Thanks.

You don't need any runtime licenses at all unless you use SQL Server.

For development, you can use the free Visual Web Developer Express Edition.
