Can i use sharepoint server 2007 with Visual Studio 2010?, Is there any issue about it to pay attention to?
A:
Yes you can. And you can use WSPBuilder also.
Issue with Workflows
There is an issue with Workflows however. If you create SharePoint workflow, you cannot add SharePoint workflow items from toolbox, they are greyed out.
A workaround is to manually add required element by editing .designer file and then you have that element in the Designer with which you can afterwards interact normally.
