SharePoint 2010 and CRM 2011 – Create a contact us form in SharePoint

Something new today.

I’m trying to create a contact us form in SharePoint ( Easy, I  know how to do that!)

Then create a new lead in CRM (We’re using CRM 2011).

Downloaded the CRM SDK 2011 and … Oh no that uses .Net 4. As SharePoint 2010 uses 3.5, this is never going to work.

What to do?

I downloaded CRM SDK 4 and used this and all worked.
