Packaging a .NET Application So It Will Run On A Computer Without .NET (3 answers)

Closed 8 years ago.

I want to run my Windows Form Application (Created Using With VS 2012 - Targeting .NET 3.5 - written in C#) on PCs that don't have .NET 3.5 installed on them.
There are many PCs out there for me to consider, and I can not do that.
So should I change my framework and I not rewrite that big project again?
Is there a way to convert the output exe file to another language that does not need .NET Framework?

Answer 1

There are tools that will package everything up into a single binary for you such as .net reactor http://www.eziriz.com/

Answer 2

You cannot compile C# .NET into native code. The only solution I see is to set the Project's Target Framework to .NET 2.0 which would allow you to XP and up no matter what.
