Keyword not supported: "data source" initializing Entity Framework Context
connection-string, entity-framework
Solution
The real reason you were getting this error is because of the `"` values in your connection string.
If you replace those with single quotes then it will work fine.

Problem
I'm initializing Entity Framework Object context, and this gives me the keyword not supported error: `metadata=res://*/MainDB.csdl|res://*/MainDB.ssdl|res://*/MainDB.msl;provider=System.Data.SqlClient;provider connection string="Data Source=.\SQLEXPRESS;AttachDbFilename=D:\Workspace\vs\Leftouch\Leftouch.Web\Data\Leftouch.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True;App=EntityFramework"` I took the connection string directly from web.config which was working, and modified only the path to the file (which I set dynamically), and instead of using the default value, used this connection string explicitly. What could cause this error?
