I was just wondering that, what is Entity Framework Connection String really mean? Like:
metadata=res://*/Models.Model1.csdl|res://*/Models.Model1.ssdl|res://*/Models.Model1.msl;provider=System.Data.SqlClient;provider connection string="data source=testSource;initial catalog=CatalogName;user id=sa;password=***********;multipleactiveresultsets=True;application name=EntityFramework"
I am aware of provider=System.Data.SqlClient; provider connection string="data source=testSource; initial catalog=CatalogName; user id=sa; password=**
Can anyone tell me what does string metadata=res://*/Models.Model1.csdl|res://*/Models.Model1.ssdl|res://*/Models.Model1.msl;
mean?
And, one more thing i need to confirm, if i want to edit in the Entity Connection String, can i do it?

A connection string is a string that contains information about a data source (usually a database engine), as well as the information necessary to connect to it.
A connection string contains initialization information that is passed as a parameter from a data provider to a data source. The data provider receives the connection string as the value of the DbConnection. ConnectionString property.
ASP.NET Core For instance, you can use the Secret Manager tool to store your database password and then, in scaffolding, use a connection string that simply consists of Name=<database-alias> . Or the following example shows the connection string stored in appsettings. json .
The providerName attribute is used to set the name of the .NET Framework data provider that the DataSource control uses to connect to an underlying data source. If no provider is set, the default is the ADO.NET provider for Microsoft SQL Server.
The metadata field is required in an EF connection string and specifies:
A pipe-delimited list of directories, files, and resource locations in which to look for model and mapping information.

Or put in other words:
The pointer to the metadata files (Conceptual Schema Definition Layer [CSDL], Mapping Schema Layer [MSL], and Store Schema Definition Layer [SSDL])
