Would it be possible to create a desktop wallet in C#?

Well hello there ;D


Why C♯?

And yes it is possible. There are already so many great bitcoin libraries written in C♯ on GitHub that you can start with.
Off the top of my head I can name BouncyCastle
http://www.bouncycastle.org/csharp
There are more in my starred repos

Because I've just finished learning ASP.NET and basic C#. I'm getting onto databases and other stuff now. I really like Bitcoin & C# so I would love to develop something in C# for the BTC community. Preferably a wallet. However, I'd firstly need to understand FULLY how they work and how to make them.

I am also new to C♯ that is why I asked, why.

I think one of the best references that you can use is Developers Guide to bitcoin
https://bitcoin.org/en/developer-documentation

The main problem with bitcoin is that it is too complicated with all the data manipulations like custom variables and stuff like that.

That said, I would love to see some projects done in C♯ for bitcoin and I promise to contribute whatever I can to any open source project even a tiny contribution.

Of course it can. Check out NBitcoin on nuget too

It is possible to have it done in any language, it just depends on the time one is willingly to put into the development.

What do you mean with "wallet"?
Does it have to include a full node or is SPV (simplified payment verification) enough?

Yes indeed. It is highly possible, but why you need to re-invent the wheel.  ;)

You have NBitcoin for bitcoin libraries
Then there is also http://stratisplatform.com/ who are building a full node in C#

FYI coinvault.io web wallet is written in C# and has some open source libraries

ofcourse this is possible .
but i am not sure how much you will be successful  .
you can make wallet for Android in about 15 minutes ( if you are sharper in typing ) .
this wallet will work on private key import .
source programming help source : YouTube 8)

15 min? I don't think he meant an SPV wallet  ;)

I guess this might help you...

Check it out..
And Yes it is possible.  :)

hehe! Thanks for taking an interest in my project but as the title suggests it is a "Watch-Only" wallet and it is used to keep tabs on your bitcoin addresses, balances and price.

What OP was looking for was a real bitcoin wallet, i assume with functionality to create addresses with private keys, sending (signing) transactions from, and all that.

Try it out mate..
I think it is possible, may need some more extra things to complete but eventually you will if you try...
Good luck...  :)

Yes it's possible to create it

You could make a full or hybrid wallet software in PowerShell or even JS or VBS, so yes [anything here] can be used to make one. Good luck going through a dozen modern-freelancers to get it half working though..


I'd code one in Rust but I don't have time and don't work for $1.50/Hr.. About $45,000.00 and thirty different third-world freelancers might get me one that does 35% functionality without crashing and I'd never have to write a line.. Then I'd write "secure" on it and retire from the investor funds and pretend all the collateral damage was "kinks"..

Lol, certainly possible to create a wallet in C#. You can also create one in assembler if it amuses you ;D

Yeah if you're one of the people who thinks hand-assembler is more efficient and economical-enough..
