MetadataProperties not found after upgrade to version 0.3.0

[xpicio]

Hello, after upgrade to version 0.3.0 it seems every lazy loaded collection crash on FilterQueryVisitor class at this line

public override DbExpression Visit(DbScanExpression expression)
{
// a bit harder to get the metadata in CSpace
var item = expression.Target.ElementType.MetadataProperties.First(p => p.Name == "Configuration");
...
}

with the exception "Sequence contains no matching element".

At the moment i'm using EntityFramework.Filters to implement soft delete on entity that use IDeferredDeletion interface. The filters are configured in this way:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
...
DbInterception.Add(new FilterInterceptor());

// Deferred deletion filter
modelBuilder.Conventions.Add(FilterConvention.Create<IDeferredDeletion, bool>("DeferredDeletion", (e, deleted) => e.IsDeleted == deleted));
...
}

then to enable or disable the filters from the UnitOfWork class:

public void DisableDeferredDeletionFilter()
{
this.DisableFilter("DeferredDeletion");
}

public void EnableDeferredDeletionFilter()
{
this.EnableFilter("DeferredDeletion").SetParameter("deleted", false);
}

With version 0.2 everything works properly. With 0.3 i need to change the configuration or is it a bug?

Bye Bye

Hi, I have the same problem with 0.3. Instead of using First, I've changed for FirstOrDefault:

`var item = expression.Target.ElementType.MetadataProperties.FirstOrDefault(p => p.Name == "Configuration");

        if (item == null)
        {
            return base.Visit(expression);
        }`

Are there any problem with this change?

Regards!
