How to deal with error "System.Data.MetadataException: Unable to load the specified metadata resource" when move edmx entity file to another project?

Cause: the res:// path changed. Need to be modified

Change connection for edmx file from
metadata=res://*/Model1.csdl|res://*/Model1.ssdl|res://*/Model1.msl;
To
metadata=res://projectname/foldername.csdl|res://*/Model1.ssdl|res://*/Model1.msl;
