Invalid object name 'dbo.UserRoles' - sql

Question

I am getting this error: [SqlException (0x80131904): Invalid object name 'dbo.UserRoles'.], but I can't catch where error is. I can retrieve other data from other tables, but not this.
conditions are:
connection string in web.config:
<add name="myStoreConnection" connectionString="Data Source=(LocalDB)\v11.0;AttachDbFilename='|DataDirectory|\myStore.mdf';Integrated Security=True" providerName="System.Data.SqlClient" />
context:
public class AdminMyStoreConnection : DbContext
{
public DbSet<UserRole> UserRoles { get; set; }
}
sql script to create database:
CREATE TABLE [dbo].[UserRoles] (
[RoleId] INT IDENTITY (1, 1) NOT NULL,
[RoleName] NVARCHAR (256) NOT NULL,
PRIMARY KEY CLUSTERED ([RoleId] ASC),
UNIQUE NONCLUSTERED ([RoleName] ASC)
);
model:
[Table("UserRoles")]
public class UserRole
{
[Key]
[DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
public int RoleId { get; set; }
public string RoleName { get; set; }
}
controller with index view:
private UsersContext db = new UsersContext();
public ActionResult Index()
{
return View(db.Customers.ToList());
}
view:
#using myStore.Helpers
#model IEnumerable<myStore.Areas.Administrator.Models.UserRole>
#{
ViewBag.Title = "Roles management";
}
<h2>Roles management</h2>
<div class="admin-container">
<div class="bcontrol">
<i class="icon-plus-sign"></i> Create New Entry
</div>
#{
var grid = new WebGrid(Model, defaultSort: "RoleId", canSort:true, canPage: true, rowsPerPage:20);
}
#grid.GetHtml(
tableStyle: "tadmin",
alternatingRowStyle: "alt",
selectedRowStyle: "selected-row",
columns:
grid.Columns(
grid.Column("RoleId",
header: "ID " + Html.SortDirection(ref grid, "RoleId"),
style: "tadmin-id"),
grid.Column("RoleName",
header: "Role Name " + Html.SortDirection(ref grid, "RoleName"),
format: #<text><a href="#Url.Action("Details", "Roles", new { id = item.RoleId })" >#item.RoleName</a></text>),
grid.Column("Control", style: "tadmin-control", canSort: false,
format:
#<text><i class="icon-edit"></i> Edit
<i class="icon-list"></i> Details
<i class="icon-minus-sign"></i> Delete</text>)
)
)</div>
and error message:

Answer 1

The problem was unfortunately very simple - as i have 2 areas - main and administrator and respectively i have 2 types of data connection, i have only 1 connection string in webconfig. after i added second line for admin context and all works
thanks for attention )
so the problem was incomplete (misconfiguration) in webconfig

Answer 2

This usually simply means a configuration issue
perhaps there genuinely is no such table
perhaps the table is there, but isn't the the dbo scheme
perhaps the db is case-sensitive (make sure that both table names are spelled correctly
Source

Answer 3

Your table name in database must be the exactly same with dbSet<> name in dbContext if not rerun the migration. (running update-databse before declaring the dbSets can lead to that problem)
Like below
