and survey model

            namespace surveyspaceproject.models          {     using system;     using system.collections.generic;     using system.componentmodel.dataannotations;     using system.componentmodel.dataannotations.schema;     using system.data.entity.spatial;      public partial class survey     {         [system.diagnostics.codeanalysis.suppressmessage("microsoft.usage", "ca2214:donotcalloverridablemethodsinconstructors")]         public survey()         {             surveyanswers = new hashset<surveyanswer>();             surveyquestions = new hashset<surveyquestion>();             //surveyusers = new hashset<surveyuser>();         }          public int id { get; set; }          public int userid { get; set; }          [required]         [stringlength(150)]         public string title { get; set; }          [column(typename = "date")]         public datetime? createddate { get; set; }          public bool isdeleted { get; set; }          [system.diagnostics.codeanalysis.suppressmessage("microsoft.usage", "ca2227:collectionpropertiesshouldbereadonly")]         public virtual icollection<surveyanswer> surveyanswers { get; set; }          [system.diagnostics.codeanalysis.suppressmessage("microsoft.usage", "ca2227:collectionpropertiesshouldbereadonly")]         public virtual icollection<surveyquestion> surveyquestions { get; set; }          public virtual user user { get; set; }          [system.diagnostics.codeanalysis.suppressmessage("microsoft.usage", "ca2227:collectionpropertiesshouldbereadonly")]         public virtual icollection<surveyuser> surveyusers { get; set; }     } } 

you have 2 issues:

issue 1

the partial class , model passing view in namespace namespace surveyspaceproject.models survey query returns in namespace. therefore different types. make sure nameplates same. error indicates.

issue 2

you have eagerly load user property. use include this:

var s = sspentity.getdb().surveys.include(x =>        x.user).firstordefault(x => x.id == id); 

now ef generate query user info included in query well.
