Could you provide any example for multiply and Divide. It seems like only sum operation is working for me.

I have not used this functionality so it is possible it may be broken.  I have some changes that I will be hopefully releasing soon.  I will check the multiply and divide feature before I release.

Thanks looking for the new bit release. I was planning to use this add in for some kind of combine calculation (2* (work planned - work remaining). That will be great if the new bit release support the combine calculation formula with different operations.

hi Vaccano,

Do you know any timeline you can release the new bit that will benefit the community?

I have most of a new release done.  But the features I added ended up not being needed for my company's TFS Server.  Thus they are mostly untested. 

I am struggling with finding time to test them myself or just removing them. 

I did look the the multiply and divide code and it seems to be working for the next release.

I will try to get something out next week, but I can't promise that for sure.

Thanks Vaccano. Looking forward for the latest release soon so we can utilize the useful features.

Sorry for not posting that version I promised.  My work (the one that pays me) has really started taking up most of my time.

I looked at this code, and it did not seem to have any thing wrong with it.  But I may have fixed any issues previously.  I am going to post an alpha version very soon.  If you feel inclined please try that out.

Thanks vaccano. Have you get a chance to release the alpha version yet?

I released the Alpha version over a month ago.

You can download it here:

I tried to get Multiple to work but it's not. It appears the double aggregateValue = 0 means that any multiplication is by 0 which = 0.
        private static bool NumericAggregation(IEnumerable<WorkItem> sourceWorkItems, WorkItem targetWorkItem, ConfigAggregatorItem configAggregatorItem)
            double aggregateValue = 0;
            // Iterate through all of the work items that we are pulling data from.
            // For link typ of "Self" this will be just one item.  For "Parent" this will be all of the co-children of the work item sent in the event.
            foreach (WorkItem sourceWorkItem in sourceWorkItems)
                // Iterate through all of the TFS Fields that we are aggregating.
                foreach (ConfigItemType sourceField in configAggregatorItem.SourceItems)
                    double sourceValue = sourceWorkItem.GetField(sourceField.Name, 0.0);
                    aggregateValue = configAggregatorItem.Operation.Perform(aggregateValue, sourceValue);

            if (aggregateValue != targetWorkItem.GetField<double>(configAggregatorItem.TargetItem.Name, 0))
                targetWorkItem[configAggregatorItem.TargetItem.Name] = aggregateValue;
                return true;
            return false;

is there any news / update with this bug? does "Multiply" is available on TFS Aggregator 2012?

May 31, 2013 at 4:41 PM
I have not fixed this one. I only have limited access to a TFS 2012 server.

When I get setup again for this I will try to fix this bug.

Any chance you have TFS 2012 setup and can work on this soon?
