If the Web server or virtual directory for your Workflow project is set to ASP.NET 1.1 rather than 2.0, this error will appear.  Workflow requires ASP.NET 2.0 to function properly. This issue is more likely to happen in an environment where the Workflow Server is being deployed on the same computer as Notification Server. Since Notification Server requires ASP.NET 1.1, special configuration must take place to allow them to coexist. Article 40939 goes into detail about this configuration.
