I'm developing a cross-platform application using Mono which communicates with smart cards via pcsc-sharp library.
Under Windows OS this library is an API wrapper of Winscard.dll
After calling the SCardReleaseContext function with Mono versions 3.2.3 and 3.3.0 application freezes and Mono process permanently takes 25% cpu.
With Mono 2.10.9 application works without any problem.
I have contacted the author of pcsc-sharp library and his investigation end up with result that it is probably Mono bug.
