            }
        }
    }
}

step 1: i took a web site application

step 2: i took a master page (.master) and 2 content pages (.aspx), of that are inherited from master page.

Step 3: i took both master page and content pages of same hierarchy in solution explorer of my application.

Step 4: when i run the application it works fine in my local system.

Step 5: when i run the application, it throws an error related to parsing kind of stuff.

as i thought:

1) either my application is not compiled properly
2) or my application thinks that the site master is located in different folder.
3) i did tried with master page virtual and type name properties, but no progress in this error.

any help would be appreciated.
