Profiling .NET 1.1 Applications

GuiProf does not directly support .NET 1.1 applications. However, you can profile them if they run with .NET Framework 2.0.

If only .NET Framework 2.0 is installed on the computer, a .NET 1.1 application will use .NET Framework 2.0 automatically. Otherwise, you can force all .NET 1.1 applications to use the latest framework by creating the following registry key:

[HKEY_LOCAL_COMPUTER\SOFTWARE\Microsoft\.NETFramework] 

"OnlyUseLatestCLR"=dword:00000001

For more information, see MSDN articles Microsoft .NET Framework 1.1 and 2.0 Compatibility and Compatibility Testing Scenarios.
