Claims Based Authentication introduced with SharePoint 2010 allows you to login to a SharePoint site using multiple Authentication Providers. In some scenario you might need to determine which Claims Authentication Type has been used to login in order to conditionally show some content. Find out how this can be done using the new Claims API provided with SharePoint 2010.
SharePoint 2010 introduced Claims Based Authentication. One of the consequences of this is the fact that in order to use Forms Based Authentication (FBA) you need to configure your Web Application to use Claims instead of Classic Authentication. One of the many changes that you notice while working with claims are different login names: while in SharePoint 2007 you used something like myprovider:myuser, SharePoint 2010 makes the claims-soup of it: i:0\#.f|myprovider|myuser. And while this is something you can take into account for newly created solutions, it can get confusing when upgrading SharePoint 2007 solutions to SharePoint 2010, especially if all you need is the user name. So is String.Replace the only way to get it out or is there a better way?
One of the great improvements in SharePoint 2010 are Web Templates. Mirjam van Olst wrote recently a great article about why using light-weight Web Templates is a better approach than using full blown Site Definitions. While using Web Templates for creating sites and Site Collections is pretty straight-forward things get complicated when you need to create the Site Collection programmatically.

Last May I’ve taken the beta versions of the two SharePoint 2010 Developer exams: 70-573 TS: Microsoft SharePoint 2010, Application Development and 70-576 PRO: Designing and Developing Microsoft SharePoint 2010 Applications. Today I received an e-mail saying that I successfully passed both exams and received the Microsoft Certified Professional Developer SharePoint 2010 status.
