Welcome to the Grasshopper 2.0 forum, which is where the Grasshopper team will post interim previews and share ongoing plans. Please submit your questions, bugs, improvements, and suggestions here.

For starters, we're posting today the first preview of Grasshopper 2.0, which introduces support for the Microsoft Visual Studio 2005 IDE and the .NET Framework 2.0.

- Check the preview release notes (http://dev.mainsoft.com/default.aspx?tabid=236) to find out about system requirements, the technologies, functionalities and limitations of this preview.

- Download it here (http://dev.mainsoft.com/Default.aspx?tabid=238). We suggest you load it side-by-side with Grasshopper v 1.8, which we recommend you continue to use for your cross-platform development.

- Check out the ASP.NET 2.0 Personal Web Site Starter Kit (http://dev.mainsoft.com/default.aspx?tabid=235): compile it and run it on Tomcat. This starter kit demonstrates quite a lot of new ASP.NET 2.0 capacities: master pages; themes; Web configuration; navigation functionalities like sitemap, bread-crumbs, and menus; Web security functionalities like memberships, roles, and authorization; and Login controls: Login, LoginView, and CreateUserWizard.

This Technology Preview features several new technologies that comprise Grasshopper 2.0:

- The integration with the Visual Studio 2005 IDE has been redesigned to plug-in seamlessly with the latest platform. We've decide to use the Web Application Project (http://msdn.microsoft.com/asp.net/reference/infrastructure/wap/default.aspx) that provides the required infrastructure to create cross-platform and multiplatform web projects, rather than the file system based Web site.

- The Grasshopper cross compiler has been re-engineering in managed code to better integrate the MSIL and Java bytecode manipulation libraries. It works with Cecil (http://www.mono-project.com/Cecil) to parse MSIL code and with ASM (http://asm.objectweb.org) to generate Java bytecode. This way, we focused on our expertise on our core competency: mapping the MSIL instruction sets to the Java bytecode. Note that this preview supports iterators, yield, nullable types, anonymous methods, and Generics (with some temporary limitations detailed in the Release Notes (http://dev.mainsoft.com/default.aspx?tabid=236).

- A .NET Framework upgraded with many 2.0 classes, especially around ASP.NET 2.0. Support for most new controls, except webparts that will come later, support for System.Configuration, for ASP.NET Application Services (memberships, roles & profiles). This is actually the result of the continuous effort within the Mono project (http://www.mono-project.com) to develop the 2.0 functionalities. The entire Grasshopper Framework (except the core and the System libraries) is built from Mono trunk, and all new developments and fixes are made directly in the Mono trunc. Check our open source page (http://dev.mainsoft.com/Default.aspx?tabid=39) to learn how to contribute to Mono and Grasshopper Framework.

So now it's your turn: download, install, code, compile, and post your feedback here. Happy hopping!

do you plan on adding .Net GUI Application to J2EE (HTML client) support? i.e. from a rich .Net applicaiton to a 'thin' HTML-based client?

Thomas, I am not sure I do fully understand your question, but I will give it a try. We plan to fully support ASP.NET 2.0 web applications and web services. We do not plan to support Windows.Forms and not also the zero-footprint installation of Windows.Form through IE. Did I answer your question? Philippe Cohen

Hello, When do you plan to add webparts support to Grasshopper? Our company has a .Net based portal software that uses webparts. We are planning to migrate to Linux on Java EE, but cannot use your product withiut this feature. Regards Sándor Kiss Sense/Net http://english.sensenet.hu

Sándor, there 2 type of web parts - ASP.NET 2.0 WebParts and SharePoint WebParts. Currently, we do not offer support for ASP.NET 2.0 WebParts. In our Portal Edition, we have a solution for SharePoint WebParts we have a solution to take your SharePoint WebPart and deploy it to IBM WebSphere Portal on Linux.

Maksim, Thanks for the info. Unfortunately we use ASP.NET 2.0 WebParts, since our product does not rely on SharePoint. Do you plan to add support for them as well? If yes, do you have a time estimate for it? Regards Sándor Kiss

Better later than never. For now we do not have plans to work on ASP.NET web parts. As far as I know there is no one in the Mono community that is willing to invest in this feature. You can contribute it to Mono and we will integrate it. See Mono contribution page: http://www.mono-project.com/Contributing Philippe Cohen

Dileep, Please refrain from inserting the same request/post multiple times. The stack traces you have attached along with the error message show your connection string is probably missing the "server name" of the machine hosting the database your application connects to. ---- Jean
