This was some strange behavior: The ‘E-mail A Link’ option in the ECB – or whatever the SharePoint 2010 name for ‘context menu’ is – was opening up the email client (in this case Outlook 2010) with a new email that contained the word ‘Sample’ – no link to the document, just the word ‘Sample’.
I will not reveal that in 2010 that the ‘E-mail a Link’ action results in a round trip to the server for no good reason (oops) – but I will reveal that it is this round trip that caused the issue.
Resolution
Since WCF is messing with you again just because you probably wanted a site with multiple authentication schemes and did not want the headache of extending the site, add this to the site’s root web.config to make WCF clam up:
<configuration>
<system.web>
…
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
</system.serviceModel>
</configuration>
That is strike #3,9343,091, WCF!!!
BTW, this also had the nice side effect of fixing SPDesigner 2010 access to the site. Once change in place, SPDesigner could access the site.
