it's the same error as if you forgot a using in normal C# code

you mean i should add

using DllImportAttribute

using DllImportAttribute

using DllImportAttribute

using DllImportAttribute?'

i don't use this scripting stuff but you have a line with what look like usings

i'll try

Ddas Vainstaintisch you mean i should add `using DllImportAttribute`?'

i added this, and nothing was changed
