Use Framework 1.1
-
Until now i developed an application with VS.Net and the framework 1.03705. Because i want to use a typ, that is only available in framework 1.1, i changed all references of my project. After i that the wanted typ is available, i can compile my project without errors, but when i want to execute it, i get error messages like these: An unhandled exception of type 'System.TypeLoadException' occurred in system.dll Additional information: Invalid PInvoke metadata format. An unhandled exception of type 'System.TypeLoadException' occurred in HolziSW.exe Additional information: Could not load type System.Runtime.Serialization.Formatters.TypeFilterLevel from assembly mscorlib, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089. Please help.
