MVC3 Login using web.config, Error "It is an error to use a section registered as allowDefinition='MachineToApplication' "

Question

I'm creating a very simplistic MVC3 website. I need to add no database authenication.

I'm using a standard MVC project with the scaffolded account controller.

In the web.config file I have

        <authentication mode="Forms">
            <forms loginUrl="~/Account/LogOn">
                <credentials passwordFormat="Clear">
                    <user name="admin" password="mypassword" />
                </credentials>
            </forms>
        </authentication>

I get the following error. (I'm using casinni, This error is usally because an Application hasnt been declared)

It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.

Any ideas how to fix?

Answer 1

I've been a massive numpty! I've been editing the wrong web.config file!

I edited the one under the /views folder when I should have edited the one under the root, doh!

Try Build and clean the solution. I have to do it after I publish. Also see this question
