The User Profile Synchronization service does not start on a stand-alone installation of SharePoint Server 2010

SharePoint Server 2010  has two installation options:
1- Complete Installation:
     You can add more Web Front End Servers,  Application Services Servers, and DataBase servers to your
    farm.
2- Stand-alone Installation:
    This installs all the components of SharePoint on one server, and you don't have the possibility to join more
     servers to the Farm.

One of the limitations of Stand-alone Scenario is:
"The User Profile Synchronization service is not designed to work on a stand-alone installation of SharePoint Server 2010."

New SharePoint Developer Features in VS2010 SP1 – Unit Testing and IntelliTrace (Saaid Khan)

As part of VS 2010 SP1 SharePoint developers can now take advantage of IntelliTrace as well as create unit tests that use SharePoint API’s.

With 64-bit support now enabled in IntelliTrace, you can use IntelliTrace in your SharePoint farm solutions. You can set a break-point in your code or break execution and then view the IntelliTrace data. You can also collect IntelliTrace data and save the .itrace log file for viewing at a later time. Check out Justin Marks great article on IntelliTrace in VS2010.

For those SharePoint developers that create unit tests, you can now create and execute unit tests for your SharePoint 2010 solutions if they use SharePoint API’s. In order to execute these unit tests you first need to deploy your SharePoint solution to your local developer machine. After that, you can execute the unit tests as you would normally.
