Looking for an easy way to run performance profiling all your cool new Silverlight applications?  Did you know that Visual Studio 2010 has the tools – you just need to know how to find and start them ;-)

Check-out this blog post about the profiler capabilities in Visual Studio 2010 – sometimes you still have to drop to the command prompt to get what you need:

This command line window has predefined PATH that includes profiler command line tools:

Next, change to the directory where your Silverlight binaries are compiled:

>cd c:\Breakout\Breakout\Bin\Release

Start the profiling session with these commands:

>VSPerfClrEnv /sampleon

>"c:\Program Files (x86)\Internet Explorer\iexplore.exe" C:\Breakout\Breakout\Bin\Release\TestPage.html

>VSPerfCmd /start:sample /output:MyFile /attach:<PID of iexplore.exe process>

<Run your scenario>

>VSPerfCmd /detach

>VSPerfCmd /shutdown

>VSPerfClrEnv /off
