I have hired a software development company to develop one software for my company using .NET framework. I am not very technical when it comes to programming language. I gave them detailed requirements and about 30 various modules that I needed in my software. Now we are at the final stages of finishing the software and I asked them to give me an exe file for desktop application and also covert it into Windows Universal Platform so it can be loaded onto windows based tablets as an app. They said they would do this. Now it occurred to me that if there could be any way we could also convert this app into iOS and Android App. When I did some research I came to know about something called Xamarin. My question to this forum is that is it possible to use the same .NET based application on visual studios to create an iOS and Android Apps? I asked my software development company about this and they said they have no clue about this. If this is possible then I can insist them on creating iOS and Android Apps at an extra cost. But before that I wanted to make sure that it was possible.
I would greatly appreciate if technical people from this forum can help me and educate me on this.
