It'll be a desktop wallet, of course. I have good experience in C#. Good enough to attempt making something like this, at least (in my opinion). If anyone would be good enough to give me some good advice, show me some good references, show me some source code or just give me help with coding this; make sure to post the information below or just PM me.
I'll attempt to make the UI look as good as possible and make the overall user experience great. I'll make it functional, put in multiple different ways of measuring BTC, different fiat currencies and different languages.
I think this'll be a good project to help me practice C# and make something cool in the process.
If someone shows you the source code,when would you learn ? I doubt there are open sources for this,you might want to curate all the public repos on github with keywords,c# and bitcoin wallet.
Don't forget to put the code on GitHub!
Just practice AND release it for free
