Question

I have a website made in Asp.net MVC which is installed in the root directory of shared hosting enviroment.

Now, I have made a mobile version for this site in Asp.net MVC and installed it as a sub-domain http://m.price-tag.org which points to a folder m(set as virtual directory) in root directory.

When someone visits the site from mobile, an assembly qualified name error is shown which goes off when the page is refreshed. Following is the screen-shot for iPhone emulator which displays the same error. Even in emulator, the error goes when the page is refreshed.

The strange part is that the type mentioned in error is used in my main website and not the mobile website. Why is this happening when my mobile project is completely different and has its own web.config but somehow, it seems that the root’s web.config is used ? Can this be a web.config issue

NOTE:- Both projects have their own EntityObject, Models and Web.config files and nothing is shared between them.

EDIT:- This error shows in mobile only…..And that too first time, if one refreshes the page, it goes away.

You need to use inheritInChildApplications, so that application inside sub directory will not use the root application configuration. See this for detail.

For appSettings section, one can’t use location tag. Therefore configurations which uses key/value pair, one needs to use the clear tag in child directories web.config
