Hi,
Something weird has started happening to my project with Dynamic Data. Suddenly I am now getting connection errors when going to the DD navigation pages, but things work fine on the default DD main page, and also other MVC pages I've added in myself work fine to the database. Any ideas?
So in summary if I go to the following web pages:
custom URL for my custom controller - this works fine, including getting database data
main DD page from root URL - this works fine
click on a link to a table maintenance page from the main DD page - GET DATABASE CONNECTIVITY ERROR
Some items:
* I'm using SQL Server Express 2008
* Doesn't seem to be any debug/error info in VS2010 at all I can see
* Web config entry:
<add name="Model1Container" connectionString="metadata=res://*/Model1.csdl|res://*/Model1.ssdl|res://*/Model1.msl;provider=System.Data.SqlClient;provider connection string="Data Source=GREG\SQLEXPRESS_2008;Initial Catalog=greg_development;Integrated Security=True;MultipleActiveResultSets=True"" providerName="System.Data.EntityClient"/>
