> Project: TinkerPop
> Issue Type: Bug
> Components: dotnet

>
> This was first reported for JanusGraph.Net:
> [https://github.com/JanusGraph/janusgraph-dotnet/issues/140]
> but the issue is most likely in Gremlin.Net.
> {code:java}
> System.InvalidOperationException: Collection was modified; enumeration
> operation may not execute.
> at
> System.Collections.Generic.Dictionary2.KeyCollection.Enumerator.MoveNext()
> at
> Gremlin.Net.Structure.IO.GraphBinary.TypeSerializerRegistry.GetSerializerFor(Type
> valueType)
> at Gremlin.Net.Structure.IO.GraphBinary.GraphBinaryWriter.WriteAsync(Object
> value, Stream stream, CancellationToken cancellationToken)
> [...]{code}
> The problem is most likely that the driver iterates over all supported types
> in a {{foreach}} loop to find a type to which the type to be serialized can
> be assigned which means that the same serializer can be used. Then this
> serializer is registered for the new type which modifies the collection the
> {{foreach}} is iterated on, leading to this error.
