I'm using MVC5 with EF6, where in my routing constraints, the "Match" function search for a value in the repository
But there are a lot of errors in my log files related to this search part, such as:
1.

As you might see, all those errors related to the same "GetSubjectBasicModel",
any ideas how to solve this ?
I'm also attaching my connection string,
<add name="DBContext" connectionString="Data Source=XXX;Initial Catalog=XXX;Persist Security Info=True;User ID=XXX;Password=XXX;Pooling=False" providerName="System.Data.SqlClient" />
I found it - Managing EntityConnection lifetime
it seems that it was multithreading issue,
the problem was solved by creating an instance of context per web request

I don't understand why I'm getting a syntax error when this line of code executes:
return ((IObjectContextAdapter)this).ObjectContext.ExecuteStoreQuery<Kitti_getProductGroupDetail_Result>("Kitti_getProductGroupDetail #ProductGroupId", #params);
Here is the whole method:
public virtual ObjectResult<Kitti_getProductGroupDetail_Result> Kitti_getProductGroupDetail(Guid ProductGroupId)
{
var #params = new SqlParameter[]
{
new SqlParameter("ProductGroupId", ProductGroupId)
};
return ((IObjectContextAdapter)this).ObjectContext.ExecuteStoreQuery<Kitti_getProductGroupDetail_Result>("Kitti_getProductGroupDetail #ProductGroupId", #params);
}
Here is the calling method:
public System.Collections.Generic.IEnumerable<ProductDetail> getProductDetailsFromSP(Guid ProductGroupId)
{
System.Collections.Generic.List<ProductDetail> productDetailList = new System.Collections.Generic.List<ProductDetail>();
using (var context = new EFDbContext())
{
var result = context.Kitti_getProductGroupDetail(ProductGroupId);
foreach (Kitti_getProductGroupDetail_Result res in result)
{
ProductDetail productDetail = new ProductDetail();
productDetail.ProductId = res.productid;
productDetail.SizeId = res.sizeid;
productDetail.SizeDescription = res.sizedescription;
productDetail.SizeRank = res.sizerank;
productDetail.ColorId = res.colorid;
productDetail.ColorDescription = res.colordescription;
productDetail.ColorRank = res.colorrank;
productDetail.QuantityRemainingInStock = res.quantityremaininginstock;
productDetail.ProductGroupId = res.productgroupid;
productDetail.ProductGroupName = "ProductGroupName is currently not in the stored procedure or in EF";
productDetail.Description = res.description;
productDetailList.Add(productDetail);
}
}
return productDetailList;
}
The result object:
public partial class Kitti_getProductGroupDetail_Result
{
public System.Guid productid { get; set; }
public System.Guid productgroupid { get; set; }
public string description { get; set; }
public decimal price { get; set; }
public Nullable<System.Guid> colorid { get; set; }
public string colordescription { get; set; }
public int colorrank { get; set; }
public Nullable<System.Guid> sizeid { get; set; }
public string sizedescription { get; set; }
public int sizerank { get; set; }
public int quantityremaininginstock { get; set; }
public string productname { get; set; }
public string imagesrc { get; set; }
}
Finally here is my stored procedure:
ALTER PROCEDURE [dbo].[Kitti_getProductGroupDetail]
#ProductGroupId uniqueidentifier
-- Insert statements for procedure here
SELECT product.ProductId as 'productid', product.ProductGroupId as 'productgroupid', product.[Description] as 'description'
, product.Price as 'price', product.ColorId as 'colorid', color.ColorDescription as 'colordescription', color.ColorRank as 'colorrank',
product.SizeId as 'sizeid', size.SizeDescription as 'sizedescription', size.SizeRank as 'sizerank', product.QuantityRemainingInStock as 'quantityremaininginstock',
product.Name as 'productname', product.ProductImageSrc as 'imagesrc'
FROM dbo.Product product
INNER JOIN dbo.Color color
on color.ColorId = product.ColorId
INNER JOIN dbo.Size size
on size.SizeId = product.SizeId
INNER JOIN dbo.ProductGroup productgroup
on productgroup.ProductGroupId = product.ProductGroupId
WHERE product.ProductGroupId = #ProductGroupId
AND product.QuantityRemainingInStock > 0
ProductGroupId is definitely getting populated. What doesn't EF like about my code? I have a similar method that does not require a parameter to execute the stored procedure - it works fine
// this works just fine
public virtual ObjectResult<Kitti_getProductDetailsAndCategory_Result> Kitti_getProductDetailsAndCategory()
{
return ((IObjectContextAdapter)this).ObjectContext.ExecuteStoreQuery<Kitti_getProductDetailsAndCategory_Result>("Kitti_getProductDetailsAndCategory");
//ExecuteFunction changed to ExecuteStoreQuery
}

The operation failed because an index or statistics with name 'IX_CuratedFeed_PackageRegistration' already exists on table 'CuratedPackages'.
This actually was a bug and has been resolved now. Check this - Update-Database failed because an index or statistics with name 'IX_CuratedFeed_PackageRegistration' already exists on table 'CuratedPackages'.
Currently working with codefirst v5 on .net 4.5
I have 1 'master' context which includes a locations table called 'Geonames' (snippet below)
public class CoreContext : DbContext
: base("Conn")
{
public DbSet<GeoName> GeoNames { get; set; }
}
The reference here is simply to be able to manage migrations on the table.
Site will have the ability to 'plug-in' different location providers and the geonames table is there to provide a local provider implementation.
The provider is set in the configuration of the website simply setting the classname and namespace of the actual implementation.
It uses an interface like this (simplified)
public interface ILocationProvider
{
IEnumerable<Location> LocationsByName(String Name);
}
The concrete implementation is instantiated as below (simplified)
public static ILocationProvider GetLocationProvider()
{
ILocationProvider Provider = null;
Provider = Activator.CreateInstance(Type.GetType("{selected namespace.classname}")) as ILocationProvider;
}
catch (Exception ex)
{
throw ex;
}
if (Provider == null)
{
throw new NullReferenceException("Could not create an instance of the location Provider");
}
return Provider;
}
The concrete implementation is as follows(simplified)
public class LocalLocationProvider : ILocationProvider
{
public IEnumerable<Location> LocationsByName(string Name)
{
List<Location> locations = new List<Location>();
using (var db = new LocalLocationContext())
{
foreach (var item in db.GeoNames.Where(X => X.Name.Contains(Name)))
{
locations.Add(
new Location { Id = item.Id, Name = item.Name, GeoLocation = item.GeoLocation }
);
}
}
return locations;
}
private class LocalLocationContext : DbContext
{
public LocalLocationContext()
: base("Conn")
{
Database.SetInitializer<LocalLocationContext>(null);
}
public DbSet<GeoName> GeoNames { get; set; }
}
}
The concrete implementation instantiates just fine and I call the method 'LocationsByName' .. but here the trouble starts. When the code line below executes
foreach (var item in db.GeoNames.Where(X => X.Name.Contains(Name)))
{
..
}
I get the following error.

I have tried to instantiate 'LocalLocationContext' without using the 'Activator.CreateInstance()' method I can query the data just fine.
To me it seems obvious that it has got something to do with how I get my actual implemention of the location provider just can't spot what the error or issue is.
Thanks in advance.

Apparently, the entity object has been fetched from the database before. If you add it to the context it will get EntityState.Added, which means that EF will try to insert it. And apparently you generate a primary key value client-side (i.e. not in the database), so EF tries to insert it with an existing PK value.
Since this is the DbContext API (apparent from the Set method, but always helpful to tag explicitly) you can use the IDbSetExtensions.AddOrUpdate method to let EF figure out whether the object needs to be inserted or updated.
