I have seen a return on investment using Microsoft .NET Framework.

The solution is worth the money. We have received a return on investment. Approximately 30 percent annually.

I definitely see a return on investment.

.NET Framework is a good tool to add value to our company.

My company has not looked at the tool from an ROI perspective since it is a product we need to use. Along with the stack of Microsoft products, Microsoft .NET Framework is a tool that works for our company.

I can't measure ROI, because I've never used a different technology stack.  Switching from one to another has not been an issue. 

The ROI is excellent.
