c# - Default code generated by my EF model has errors -

this kind of noob question, , bit embarassed have not been able figure out myself , knew transition linqtosql ef fraught nuances this.

basically did

1> create musicstore sql database using visual studio 2012 server explorer 1 table.

2> added new ado.net entity data model edmx , generated using wizard pointing database in step 1.

this gave me diagram of musicstore table. if change code generation strategy in properties default instead of none, code generated in musicstoremodel.designer.cs.

however, @ public musicstoreentities() : base("name=musicstoreentities", "musicstoreentities")

i has invalid arguments .

what missing here? reference? appreciated.

public partial class musicstoreentities : objectcontext {     #region constructors      /// <summary>     /// initializes new musicstoreentities object using connection string      ///found    in 'musicstoreentities' section of application      ///configuration file.     /// </summary>     public musicstoreentities() : base("name=musicstoreentities", "musicstoreentities")     {         // getting compilation error @ line below         this.contextoptions.lazyloadingenabled = true;         oncontextcreated();     } 

this design. please refer following link microsoft's official position: entity framework 5 code generation strategy set default causes errors on properties of entities.

(...) reason seeing these compile errors because re-enabling legacy code generation without disabling new t4 based code generation. means 2 sets of classes being generated. page provides details on how revert objectcontext code generation - http://msdn.microsoft.com/en-us/data/jj556581.
