Error in assemblyinfo.cs when the framework is changed

Question

Hi,

I have an Office application which is building properly on .Net 4.0. I need to change it to .Net 3.5. Once I change it in the settings I am getting this error

The type or namespace name 'SecurityRulesAttribute' does not exist in the namespace 'System.Security' (are you missing an assembly reference?)

Do I have to refer a different System.Security assembly?

Thanks

Answer 1

Security, especially CAS, changed a lot between 3.5 and 4.0. Even more, from documentation page regarding this class we can see that it was introduced in 4.0. How did you manage to compile it against 3.5 framework?

Answer 2

I removed the conflicting line and no errors now. Waiting for repercussions...
