We're looking to read some QR codes in a Windows 8 Metro app. .NET libraries we've used in the past can't be referenced in WinRT/Metro and porting them won't be easy because they depend on System.Drawing which isn't in the .NET for Metro style apps. We looked at this by Benjamin Soulier but it didn't seem to work. Any other suggestions or something easy we're missing?
Thanks
You can use ZXing.Net: http://zxingnet.codeplex.com/ For Metro apps based upon HTML5/Javascript I'm currently working on a port of zxing.net for Windows Runtime Components WinMD. You can get the source from here https://zxingnet.svn.codeplex.com/svn/branches/WINMD (btw. I'm the creator of ZXing.Net (a port of the java based ZXing))
Based on feedback from MS resources, there is nothing built in and no frameworks they were aware of yet.
Quick way to try is by using Esponce web service. Make a simple HTTP POST request to http://www.esponce.com/api/v3/decode?format=png and send image data in body. Response should contain something like that:
{"content":"here goes content decoded from QR Code"}
Web services are platform-independent (easy to port) and lightweight on client side.
