I’m using a WCF perfectly for most of the cases.

When I try to call it with more than a certain number (like 20) of objects in a list (not too complex objects) as a parameter it seems like it can’t even reach the service. I’m in debug mode and it doesn’t even starts the service execution.

I thought it was because of MaxArrayLength and other Service configuration but I have tried everything and anything changed. You can see my Service Configuration in the picture.

Do you have any suggestion?? Should I change anything in my client configuration???

Thanks in advance!!

    It is likely you haven’t set a higher value for the maxItemsInObjectGraph for DataContractSerializer.

    <dataContractSerializer maxItemsInObjectGraph="2147483646"/>
