When we display our ASPX page hosted on a Windows Server 2003 using VS Express for WEB they display properly. We recently migrated to a new Windows Server 2012 host and are using VS 2015 community. The website appears to be running fine but when we try
to display any ASPX in Design View we get a Master cannot load error. We were using Front Page extensions on the 2003 Server and I understand that they are not used by Windows Server 2012.
ERROR MESSAGE: Severity Code Description Project File Line 147 Warning - (calls out code below in Web.config)
ASP.NET runtime error: 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.
What directory holds the application named "membershipApp"? Is it an executable or and ASP Control within ASP.net? I am accessing the code on the server remotely via FTP from my computer.
<membership defaultProvider="AspNetSqlMembershipProvider">
<providers>
<clear/>
<add name="AspNetSqlMembershipProvider" type="System.Web.Security.SqlMembershipProvider" applicationName="membershipApp"/>
