Unable to compile project

[ranjancse26]

I see the below errors. Please help me.

Using neo.smartcontract.framework\3.0.0-preview5

error CS0246: The type or namespace name 'ContractPermissionAttribute' could not be found (are you missing a using directive or an assembly reference?)

Could you create a dummy project that could help us for test your problem? It seems that the nuget it's not referenced or the using it's wrong.
