Guest Editorial

Dear Readers,

This volume contains extended versions of five papers selected among the contributions to the .NET Technologies 2005 conference. The conference was held in Pilsen, Czech Republic, from May 30 to June 1, 2005.

The purpose of the .NET Technologies conference series is to bring together researchers and practitioners from academia and industry to discuss the latest developments in .NET and advance the state of the art in the research on related technologies. Interest in these topics has been continuously growing as a consequence of the importance and the ubiquity of object-oriented technologies. For .NET Technologies 2005, papers describing theoretical and practical results were sollicited in the following areas:

• software engineering,
• programming languages and techniques,
• parallel and distributed computing,
• algorithms and data structures,
• educational aspects of .NET,
• support for .NET on other platforms.

We accepted 16 out of 42 submitted papers for the presentation at the conference. The authors of of the best papers were invited to submit an extended version of their article to this JOT issue. We finally selected five articles for publication.

We would like to thank the authors of submitted papers for the high quality of their contributions. We are very grateful to the programme committee members for establishing a selective conference programme. We highly appreciated the work of the referees who helped us select the best articles for this special issue of JOT.

Best regards,
