Right now we have version .Net 2008 Vol 1, CLR 2
(8.1.20081.1000) for windows forms.
We are thinking to upgrade.
We also have been told that 2 bugs that disturbed us have been solved in the later versions.
We use .Net 2 visual studio 2005 right now.
We will probably upgrade our visual studio to .net 3.5 sometime, but we havent decided yet.
Which version would you recommend to upgrade, and will it be backword compatible?
The version we are using has problem with large data.
We get out of memory exception, when we try to load 70,000 rows on 80 columns.
Is it solved in later versions?
All versions of NetAdvantage for WinForms are backward compatible with older versions, so I recommend getting the latest version, always.
There are occasional changes in behavior due to bug fixes. But generally speaking if there is a change in behavior that breaks your application, it's usually considered a bug - unless the change was made specifically to fix a bug which your code happened to be working around or relying on.
In any case, the best thing for you to do would be to download the trial version of NetAdvantage, make a backup copy of your project, and then upgrade it to the new version and try it out.
You can have multiple versions of NetAdvantage installed on your machine and the new version will not affect the older version(s). I, personally, have about 6 different versions on my machine that I run simultaneously.
