MetadataException: Unable to load the specified metadata resource
I hope someone can help with this. i have tried following other posts on here and dozens on other sites but i can get this working.
the entity framework was all working, then the next day just started giving me the error: Unable to load the specified metadata resource. on the constructor of the entities class.
I have checked the connection strings, deleted and re added everything but i still cant get this working.
my model namespace is WraithNath.co.uk.Models
the metadata artificat is embed in assembly
my connection strings are as follows:
<add name="ConnectionString" connectionString="Data Source=.\SQL2008;AttachDbFilename=|DataDirectory|\WraithNath.co.uk.mdf;Integrated Security=True;" providerName="System.Data.SqlClient" />
<add name="Entities" connectionString="metadata=res://*/Models.WraithNath.co.uk.csdl|res://*/Models.WraithNath.co.uk.ssdl|res://*/Models.WraithNath.co.uk.msl;provider=System.Data.SqlClient;provider connection string="Data Source=.\SQL2008;AttachDbFilename=|DataDirectory|\WraithNath.co.uk.mdf;Integrated Security=True;MultipleActiveResultSets=True"" providerName="System.Data.EntityClient" />
I cant find the 3 files i need in the assembly when looking at it in Reflector.
Is there a step by step guide to sort this out? i have already tried every link on the first 3 pages of google for search results 'entity framework Unable to load the specified metadata resource'.

Craig Stuntz has written an extensive (in my opinion) blog post on troubleshooting this exact error message, I personally would start there.
The following res: (resource) references need to point to your model.
<add name="Entities" connectionString="metadata=
res://*/Models.WraithNath.co.uk.csdl|
res://*/Models.WraithNath.co.uk.ssdl|
res://*/Models.WraithNath.co.uk.msl;
Make sure each one has the name of your .edmx file after the "*/", with the "edmx" changed to the extension for that res (.csdl, .ssdl, or .msl).
It also may help to specify the assembly rather than using "//*/".
Worst case, you can check everything (a bit slower but should always find the resource) by using
<add name="Entities" connectionString="metadata=
res://*/;provider= <!-- ... -->
