ObjectContext Constructor (String, String)

Initializes a new instance of the ObjectContext class with a given connection string and entity container name.

Namespace:  System.Data.Objects
Assembly:  System.Data.Entity (in System.Data.Entity.dll)

	String^ connectionString, 
	String^ defaultContainerName


Type: System::String
The connection string, which also provides access to the metadata information.
Type: System::String
The name of the default entity container. When the defaultContainerName is set through this method, the property becomes read-only.


The connectionString is nullptr.


The connectionString, defaultContainerName, or metadata workspace is not valid.

The connectionString is a string that contains information that is required to access a conceptual model and to connect to a data source. The EntityConnectionStringBuilder class can be used to correctly format the string.
