InfoPath Dev

Hello,

... unfortunately I personally have not installed a SharePoint 2010 test system by now.

But I would like to ask if anyone can share the experiences with Infopath 2007 webforms under the hood of SharePoint 2010. Is it really full compatible or do I have to change specific functions...

I have a lot of (full trust) forms with managed code and a lot of controls (even with the use of contact selector controls).

It would be nice if anyone can share the experiences with this...

Thank you and regards,

Your 2007 browser forms will work right out of the box in 2010 unless they include custom code.  However, since you have a lot of custom code, I can't say for sure.  I do all of my forms without code, and there is no discrepancy from 2007 to 2010.  I have also built some 2010 browser forms with Qdabra qRules code that I was able to publish without going through Central Admin thanks to the sandbox.  However, I don't have any code-behind 2007 forms that I've tried to bring over.
