I wanted to create a site template package. Instead of going with a custom site definition, I planned to go with the recommended "Provisioning Provider" technique. The solution was going just fine. created all my features and modules, in the provisioning class I added them to my site one by one and it was working. One I added the module responsible for provisioning the content types, the package stopped working and started receiving the error "Invalid field name {GUID}", whenever I try to create a site collection, where the {GUID} is the GUID of the first field in the content type fields XML tags.

My content types XML is fairly simple:

<Elements xmlns="http://schemas.microsoft.com/sharepoint/">

and my provisioning class looks like this:

public override void Provision(SPWebProvisioningProperties props)
        {
            // apply template using a configuration for Blank Publishing site
            props.Web.ApplyWebTemplate("BLANKINTERNET#0");

            SPSecurity.RunWithElevatedPrivileges(delegate()
            {
                using (SPSite siteCollection = new SPSite(props.Web.Site.ID))
                {
                    using (SPWeb site = siteCollection.OpenWeb(props.Web.ID))
                    {

                        siteCollection.Features.Add(new Guid("a6bce603-1626-41ff-a107-3561f379be6d"));

                        site.Title = "Research Center Site Title";
                        site.Description = "This site was created on " + DateTime.Now.ToShortDateString();
                        site.Update();
                    }
                }
            });
        }

is there any known issue regarding creating content types using the provisioning providers?

You need to have a "Name" property, "DisplayName", etc on the fieldref in addition to just the GUID. Here is a link to the FieldRef element. Check the required fields.

It Worked. after adding the name and the display name attributes. Strange though because VS 2010 is not enforcing these attributes for the fieldRef element –  Mohammed Shokry Jun 13 '11 at 7:12
    
Visual Studio's intellisense can be spotty both in terms of missing required elements, and identifying invalid elements. You can't really trust it. –  Chris Beckett Jun 13 '11 at 19:03
