c# - edit user profile image with usermanager -

i'm following this tutorial add profile picture once account create.

that edit has following snippet,

student student = db.students.include(s => s.files).singleordefault(s => s.id == id); 

in above example applied table call student in case want go aspnetuser table , have go usermanger feature , once try include file popping error in compile time.

but in scenario i'm trying include in aspnetuser or usermanager

so populate uploaded picture. need include following code in user manager

var user = await usermanager.include(s => s.files).findbyidasync(userid); 

but getting following error

'applicationusermanager' not contain definition 'include' , no extension method 'include' accepting first argument of type 'applicationusermanager'

how ignore , include files

edit:

these changes i've done in model classes

file

public class file {     public int fileid { get; set; }     ..      public virtual applicationuser usermanager { get; set; } } 

filepath

public class filepath {     public int filepathid { get; set; }     ..      public virtual applicationuser usermanager { get; set; } } 

applicationuser

public class applicationuser : identityuser {         ....          public virtual icollection<file> files { get; set; }         public virtual icollection<filepath> filepaths { get; set; }      public async task<claimsidentity> generateuseridentityasync(usermanager<applicationuser> manager)     {        ....     } } 

aspnetuser

public partial class aspnetuser {      public aspnetuser()     {        ..     }     ....      public virtual icollection<file> files { get; set; }     public virtual icollection<filepath> filepaths { get; set; } }

then try add migration project typing following pmc:

add-migration file

add-migration filepaths

then getting following error in console

no migrations configuration type found in assembly 'project_name'. (in visual studio can use enable-migrations command package manager console add migrations configuration).

---

then typed following pmc:

enable-migrations project_name.models.sampleentityframeworkentities

then got following error in console

creating dbmodelbuilder or writing edmx dbcontext created using database first or model first not supported. edmx can obtained code first dbcontext created without using existing dbcompiledmodel.

---

then try migrate files , filespath using following code

add-migration file

add-migration filepaths

get error in console

creating dbmodelbuilder or writing edmx dbcontext created using database first or model first not supported. edmx can obtained code first dbcontext created without using existing dbcompiledmodel.

if understood correctly you're trying follow guide using asp.net identity. asp.net identity unique system own classes , dbcontext. in order add new fields user need modify applicationuser class. add property class , apply migration if needed. add new column aspnetuser. add field viewmodel (if any) , other logic required work field.
