Diagnostic Information


Diagnostic information about the application

Use .Net Performance Validator to

  • Identify slow (time consuming) functions in your application.
  • Identify busy (called very often, not necessarily slow) functions in your application.
  • View application behaviour in real time.
  • Improve your software quality testing with interactive, profiling displays.
  • Create profiling reports with collapsible call tree and call graphs to share with your team on your intranet.

Easy to use

To use .Net Performance Validator all you need is debugging information for your application and .Net Performance Validator can get to work. .

You do not need to modify your software, recompile or relink your software to use .Net Performance Validator..

  1. Launch your application with .Net Performance Validator.
    .Net Performance Validator will launch and attach to your application.
  2. Run your application as normal.
  3. Close your application.
  4. Examine the profiling statistics that .Net Performance Validator generates as your application runs.

Easy to read data displays show you the performance statistics as your application executes. You do not need to wait until your application has finished to view statistics for any function, file or DLL. The displays can be filtered to show you only the information that you want to work with.

Detailed, colour coded source code shows at-a-glance which functions and lines have executed and how long each took.

Code Performance Source Code Detail


.Net Performance Validator can be configured to collect all data or just the data you need. Powerful filters for collecting data and for displaying collected data give you maximum flexibility and control over how much CPU time is spent and how much memory is used collecting data allowing you to choose how much effort is put into a given task.


The default options of .Net Performance Validator provide profiling data for all DLLs and files in your application that have debugging information. If you wish to only create profiling reports for selected DLLs, or exclude certain file types or even specific classes and methods, .Net Performance Validator has filtering capabilities to allow such customisation.

.Net Performance Validator provides powerful HTML and XML reporting capabilities, allowing you to produce profiling reports that you can share with your colleagues or post on your company intranet. The HTML reports can include animated collapsible call trees and call graphs.

Most profiling tools provide one display - the display that shows the profiling results. .Net Performance Validator provides additional displays to provide you with more insight into the data you have collected.


.Net Performance Validator works with any .Net application, .Net service, ASP.Net application or WPF application that outputs debug information in PDB format.

.Net Coverage Validator works with all versions of the .Net Common Language Runtime (CLR 1.0, 1.1, 2.0, 4.0) and all versions of the .Net Framework (1.0, 1.1, 2.0, 3.0, 3.5, 4.0) in 32 bit and 64 bit configurations.

We support many versions of Visual Studio: Visual Studio 2019, 2017, 2015, 2013, 2012, 2010, 2008, 2005, 2003, 2002 are supported. Use any language, C#, C++.Net, VB.Net, F#, J#, Cobol.Net.

All 32 bit Windows operating systems from Windows 10 to Windows XP are supported.

All 64 bit Windows operating systems from Windows 10 64 to Windows XP 64 are supported.

For more details, please consult the compatibility feature list


.Net Performance Validator works with applications and services, both pure .Net and mixed-mode .Net.

As well as the traditional performance profiling role that .Net Performance Validator performs, .Net Performance Validator can be used for interactive profiling and for creating profiling reports automatically as part of a regression test suite and/or overnight build.

.Net Performance Validator also allows you to automate this process by launching .Net Performance Validator from the command line. A full range of command line options allow you to perform unattended runs of .Net Performance Validator, complete with HTML export and XML export, to facilitate regression testing as part of your overnight builds.
