I need to switch between two sitemaps within a VS2005 web application website.
In my web.config file I have:
<siteMap defaultProvider="XmlSiteMapProvider">
<providers>
<add
name="AdminSiteMap"
type="System.Web.XmlSiteMapProvider"
siteMapFile="~/Master/Admin.sitemap" />
<add
name="UserSiteMap"
type="System.Web.XmlSiteMapProvider"
siteMapFile="~/Master/User.sitemap" />
</providers>
</siteMap>
Both Admin.sitemap and User.sitemap are valid XML files (as proved by opening them in IE6).
When I run the the site, I got:
Configuration Error
Description:
An error occurred during the processing of a configuration file required to
service this request. Please review the specific error details below and modify
your configuration file appropriately.
Parser Error Message: The
provider 'XmlSiteMapProvider' specified for the defaultProvider does not exist
in the providers collection.
Source Error:
Line 25: -->
Line 26: <!-- -->
Line 27: <siteMap defaultProvider="XmlSiteMapProvider">

Line 29: <add |

If I comment out the <site Map .../> block, the the starts with its default Web.sitemap with the default menu displayed correctly. I cannot readily use the ASP.NET 2.0 User/Role model as the system architecture is to use web service data access. Since XmlSiteMapProvider is the default source, why is it not being found?
Changing
<siteMap defaultProvider="XmlSiteMapProvider">
to
<siteMap>
fixed the problem! 
Why should removing the reference to the provider fix the problem?
