Closed Issue: ConventionModelBuilder should ignore indexer property [505]

It's meaningless to include indexer property to edm model. It will also cause error when user having overloaded indexer properties, like:

public class HttpHeaders
{
public string Item[string name] { get; set; }
public string Item[int index] { get; set; }
}

The exception is:
System.InvalidOperationException occurred
HResult=-2146233079
Message=Sequence contains more than one element
