In order to generate XML documentation using Web API Help Pages for my Web API project, I had to check the "XML documentation file" option under the "Builds" section of my project's properties. This correctly generates the documentation when I build locally.

However, when I check in, I get the following error on the build server:

> 
> CSC: Error generating XML documentation file
>  'c:\Builds\3...\Sources\CurrentVersion...\ProjectName\App\_Data\XmlDocument.xml'
>  ('Access is denied. ')
> 
> 
> 

I'm not sure why this happens, since it creates a new directory for each build anyway. I googled this issue and searched Stack Overflow, but the only solutions I found were to remove the XML documentation file (which defeats the purpose of using Web API Help Pages). How can I resolve this?
