When assemblies are loaded for the first time in a Microsoft .NET Framework 2.0 ASP.NET Web application, you receive the following error message:

System.IO.FileNotFoundException
Could not load file or assembly ‘AssemblyName’ or one of its dependencies. The system cannot find the file specified.

You may receive this error message if the following conditions are true:

• The .NET Framework 2.0 ASP.NET Web application references one or more class library assemblies.
• You create DEVPATH environment variables so that these assemblies locate the version of the assemblies that you want to use.

This problem does not occur if you use Microsoft ASP.NET 1.1 to develop the application.
