I have just uploaded the initial release of pesta on Google Code. The project homepage can be found here and the code is available via subversion.
Pesta is based on revision 698050 of the Java
implementation of Shindig. Pesta is based on .NET Framework 3.5 and is
implemented using C#. Out of the box, pesta is not completely complaint with OpenSocial 0.7. We are currently working on this.
The
initial release includes class libraries from the IKVM project
(www.ikvm.net). This is due to external jar files that were used by
Shindig especially those from com.google that have/could not be ported
due to time constraints or lack of source code. Due to these
dependencies, shindig.dll contains some necessary java classes to
support these external libraries. In the future, this should disappear.
