Features, Enhancements and Bug Fixes
This release of ANTS adds full support for profiling applications running under .NET 4 and Silverlight. It also adds a new very low overhead profiling mode, the ability to visualise when a method was active on the timeline and a command line tool.
Users running Windows Vista, Windows Server 2008 or later operating systems will also be able to record and analyse SQL and File I/O activity associated with their target application, as well as attach the profiler to running .NET 4 processes without restarting them.
It also includes the vastly improved IIS support, along with XBAP support, that we first shipped with ANTS Profiler 4.3.
ANTS Memory Profiler 5, also available from www.red-gate.com, is our new, completely rewritten memory profiler offering incredible performance and an unparalleled feature set.

Line-level timings are not available for Silverlight applications.
Some cheaper motherboards have an issue with their high performance timer where it can jump backwards or forwards in time by significant periods. This can cause anomalous results to appear in ANTS Performance Profiler 6 because it relies on that timer to accurately measure application performance. If you experience this issue you should upgrade your motherboard drivers to the latest version.
A limitation in Windows means that it is not possible to successfully attach to a .NET 4 process more than once.
On Windows Vista (32 bit), if you are profiling Windows Services or websites on IIS, you may have to run ANTS Performance Profiler as an administrator.
If you have Internet Explorer 7 on Windows Vista or later, it is not possible to profile websites on IIS.
On Windows Vista and Windows 7, after profiling IIS using attach to process, ANTS Performance Profiler 6 sometimes cannot stop the session. If this happens, restart ANTS Performance Profiler before starting a new profiling session.
In some cases, Windows Services do not restart properly after profiling.
To profile an XBAP application, Internet Explorer must be set as your default browser and it must be closed before profiling.
Custom event markers are not available when profiling Silverlight applications.
