Object reference not set to an instance of an object

Question

public EFRepo(DbContext ctx)

{

this.DbContext = ctx;

this.DbConnection = ((ctx as System.Data.Entity.Infrastructure.IObjectContextAdapter).ObjectContext.Connection

as EntityConnection).StoreConnection;

this.DbSet = ctx.Set<TEntity>();

}

In the above code

(ctx as System.Data.Entity.Infrastructure.IObjectContextAdapter).ObjectContext.Connection

as EntityConnection

is getting null when i am changing EF 4 to 4.5

This issue occoured when one object is null but you try to find the inner properties value. Here it may be the some where object is null. Check ObjectContext may be null or ObjectContext.Connection is null.
