however, code not compile when reference rootdirectory property. error see below

'microsoft.sharepoint.administration.spfeaturedefinition' not contain definition 'rootdirectory' , no extension method 'rootdirectory' accepting first argument of type 'microsoft.sharepoint.administration.spfeaturedefinition' found (are missing using directive or assembly reference?

now, weird part while debugging, able evaluate rootdirectory property correctly in quick debug window.

am missing obvious? said, i'm new sharepoint.

my feature scoped web level, , have reference microsoft.sharepoint.administration in using statements.

any help appreciated, thanks.

it indeed basic.

the solution/project set sandboxed. going properties of project (not property pages hitting f4 while project selected on solution explorer) , setting sandboxed false allow compile when you're accessing rootdirectory solution in code.

also, few other properties/method not show when solution sandboxed instead of marked farm solution.
