- How to Fix "The provider did not return a ProviderManifest instance ...

Full Error:
The metadata specified in the connection string could not be loaded. Consider rebuilding the web project to build 
assemblies that may contain metadata. The following error(s) occurred: 
The provider did not return a ProviderManifest instance.

Solution:
Open the EDMX file and change ProviderManifestToken="2012" to ProviderManifestToken="2008"

Other Solutions (not useful for me):
1- I know this is a ridiculous solution but i think that the star (*) is not working in connection string field of Web.config :-( you can change it with project name as a project namespace reference
Before: <add name="TestEntities" connectionString="metadata=res://*/Model1.csdl|res://*/Model1.ssdl blah blah
After: <add name="TestEntities" connectionString="metadata=res://PROJECTNAME/Model1.csdl|res://PROJECTNAME/Model1.ssdl blah blah

2- Go to Run > %temp% and empty the temp folder
3- Set integrated security=False in connection string field of Web.config
