upgrading from VS.Net2003->2005

[e_LA]

Hi Has someone any experience with such an upgrade? I am going to do that with my C# windows based application. Is it safe to install VS2005 with VS2003 already installed? Is it fully compatibile? I mean can I have installed simultanously both versions? Any advice or warning? Thanks Ela

At home I've only tried opening very simple VS 2003 apps. in VS 2005. There were no problems. Might be a different with an industrial-strength app. that you might have at work. Where I work at the moment, a colleague will shortly be attempting to open one a VS 2003 web app. in VS 2005 and seeing whether everything workss.

Yes to all. You shouldn't have any problems. VS 2005 will install side by side with VS 2003. Only issue might psossibly be the database, if you're also installing SQL Server 2005 alongside SQL Server 2000. For myself, I never had SQL Server 2000, but I did have MSDE 2000 and ran into some issues. But the upshot is that I still have MSDE 2000 installed as well as SQL Server 2005. Kevin

Thanks for the answer. If you know more from you colleague please let me know. Ela

You will certainly get quite a few warnings when you open VS 2003 projects. Some of these will be for obsolete method calls (the app. will still run, but they just suggest that you use a newer API). You'll also get warnings in HTML files because they're now tracking XHTML 1.0. But again they'll still run. C++ code will definitely be something different though! Kevin

Yes, you can safely have them installed side by side. š Cheers, Vikram.

My colleague is in the office and working on this now. He has run into mumerous problems with upgrading a VS 2003 solution! There are however a few articles dotted around on how to prepare for an upgrade, e.g., Step-By-Step Guide to Converting Web Projects from Visual Studio .NET 2002/2003 to Visual Studio 2005 http://msdn.microsoft.com/asp.net/reference/migration/upgrade/default.aspx?pull=/library/en-us/dnaspp/html/webprojectsvs05.asp[^] Kevin

Hi Kevin Thanks for the link. I am upgrading windows application not web one. However some issue will be usefull I supppose. I have upgraded my aplication and everything was fine except code written in C++. There was a change in C++ compilator in VS2005 and I am struggling with that now :-( Ela

[Kevin McFarlane]

OK, yes you'll have fewer problems with windows forms than ASP.NET.

Yes, I warned you that you might have problems with C++! :) Try googling on "Breaking changes in Visual C++" or something like that. A lot of the problems are to do with MS making the compiler more conformant with the C++ standard. Kevin

Kevin I have been founding in google etc. and I did not found anything usefull. However I am still looking for that. I consider to translate the C++ code to C#. I was going to do that in the future but maybe I will have to do it now. Ela
