ASP.Net Versions and Compatibility

[charles]

I ship a C# asp.net app in .dll form which is targeted at ASP.Net v1.1.

If a user loads is on a machine with ASP.Net v1.0, it crashes--no reasonable
message--just a null-pointer exception before any of my code is reached..

Is there a standard practice to detect and/or prevent this situation. I
haven't found an option in the installer to detect the asp.net version.

thanks
charles

Charles,

You can check the Registry and populate a variable in your MSI package with
the version of the Framework that is installed. You would need to use a
custom action to do it or a tool such as Wise for Windows Installer or
InstallShield to do it easily.

As for the crash you are having, here is a list of breaking changes in 1.1:
