We are currently evaluating ANTS Performance Profiler and have run into a bit of a problem. When profiling our ASP.net web application many items in the list of methods do not contain any information and instead say 'hidden methods without source'. It seems that all the rows affected by this are methods used by a 3rd party tool we use called Telerik RAD Controls for ASP.NET AJAX, however these methods are the ones that seem to take the longest so they're obviously of interest to us.
Are we doing something wrong? We're also trying out another product called Jetbrains dotTrace which does a similar job and that seems to have no problem with any of this, so in the interests of experiencing the product as it is meant to be, I wanted to see if there is something we can do to solve this problem
