Hi I have a web service method like this:

 public IEnumerable<TagData> GetTagsByTagType(string tagType) {
            Log.Debug("GetTagsByTagType Start");

            IEnumerable<TagData> query = new List<TagData>();
            try {

                using (IObjectScope scope = new PhoenixObjectScopeProvider().GetNewObjectScope()) {

                    query = from tag in scope.Extent<Tag>()
                            join tagContent in scope.Extent<TagContent>()
                                on tag equals tagContent.Tag
                            where tag.TagType == tagType
                            select new TagData {
                                                   TagId = tag.TagId,
                                                   TagType = tag.TagType,
                                                   Tag = tagContent.TagData
                                               };

                }
            }
            catch (Exception e) {
                Log.Error("GetTagsByTagType Exception.", e);

            }



            return query;
        }

I use WCFStorm to call the method. In VS i set a break point at this method. When execution his the query line something strange happens. The return query line is never hit. An exception is not caught. It's like the method just stops executing at that point. Any ideas?

Hello Adam ,

The bottom of your problem comes from the fact that you are using JOIN calls in you Linq query. Joins were not supported in the previous versions of OpenAccess including the current one. This will not be the case for the future though as joins are now fully supported by OpenAccess. The functionality will be publicly available in the next internal build/service pack.

Thank you for your patience.
