Can't view .aspx file in browser

Question

Hi,

I purchased a linux hosting in bigrock and I copied all the asp.project files in that public_html  folder in the file manager.

 

When I'm trying to open the site it is showing only the code in the page when i accessed it like this "www.domain.com/index.aspx

 

when i accessed like this www.domian.com it is showing

 

Forbidden error 403 you do not have permission to access this / directory. 

 

Please help me with hosting .aspx site in bigrock linux hosting service.
