.Net with single .exe without .NET Framework installation

Question

I wrote my simple desktop program in C#. I am reluctant to distribute it on the internet because i am not sure if users will go through pain of installing the .Net Framework. My target users are non-tech savvy users.

I am very familiar with MFC and I probably can write this program in MFC in a month. MFC is nice because I don't have to worry about distributing other components. It will be one nice single executable.

So my real question is this: Is it possible to write .Net app without worrying about distributing .Net Framework?

Update I found another solution: If you are using Innosetup, there is a script that installs .net framework. http://www.codeproject.com/KB/install/dotnetfx_innosetup_instal.aspx

Answer 1

If you use Windows Installer, it can automatically install the required version of the .NET Framework. Also, Jay is correct that the .NET Framework 3.0 is installed on Windows Vista and version 3.5 is included with Windows 7.
