Description Ciprian Khlud 2013-04-09 05:25:23 UTC
When the .Net implementation is:

Releases all resources used by the current instance of the AsymmetricAlgorithm class. (Inherited from AsymmetricAlgorithm.)

If Mono doesn't need to dispose it, it should provide an empty Dispose method to not give compiler errors when compiling both Mono and .Net source.
Comment 1 Sebastien Pouliot 2013-05-16 15:11:52 UTC
RSACryptoServiceProvider is, and always was, IDisposable because it inherits from AsymmetricAlgorithm which is IDisposable.

The AsymmetricAlgorithm.Dispose method was not public before .NET 4.0 (but still callable using IDisposable [1]). 

MS added it in .NET 4.0 and recent Mono releases (e.g. 3.0.x) also have it [2] if you're compiling againt the 4.0+ profiles. If you're using an older Mono or profile (e.g. 2.0) then you'll need to update it.

[1] e.g.

IDisposable d = new RSACryptoServiceProvider ();
d.Dispose ();
