.net 4.0 inheriting .net 3.5 web.config?

I have a .NET 3.5 web site in IIS 6. I created a virtual directory to host a .NET 4.0 app. However, I'm getting all kinds of errors that point to the .NET开发者_如何学Python 4.0 app processing items from the parent app's web.config file, even though I have it set up to be its own virtual directory.

How can I stop this from happening?

This may help you - although it explains what to do in the opposite situation.

Can I host a .net 2.0 virtual directory in asp.net 4.0 site?

Virtual directories will inherit the root directory web.config. This is by design.

Or, you can use the <remove /> element to, well, remove elements from the parent config.

give different applicaiton pools for the parent and child app from iis. Set framework 2.0 for the parent app's applicaiton pool and framework 4.0 for the child's.
