SQL Server Profiler is available for SQL Server 2008 Dev Edition?
Yes, it is available in the installer for development edition. Without firing it up, I'm not sure if the installer has changed between 2008 and 2008R2 but in 2008 there are two options for installing client tools.


Management Tools (Basic) which installs SSMS, SQLCMD and Powershell support
Management Tools (Complete) adds Profiler, Database Tuning Advisor, Integration Services, Reporting Services.
