Yesterday I and Vladimir Timashkov were speaking on developers seminar in MS office in Saint-Petersburg. Vladimir made an overview of data retrieving in Sharepoint and summarized their advantages and disadvantages. I told about Camlex.NET open source project – show its internal architecture, examples of practical usages and how we worked over it. Also we told about our experience of participation in open source projects. In another sessions Vitaly Baum told about Linq 2 Sharepoint 2010 and OData, and Michael Arhipov told about custom implementation of Linq 2 Sharepoint provider. I think such meetings are quite useful for developers as here we can share our knowledge with each other and increase our professional skills.
I uploaded our presentation on the slideshare so it can be viewed online: http://www.slideshare.net/sadomovalex/slides-4670911. Here is also link on Vitaly’s presentation: http://www.slideshare.net/butaji/sharepoint-openxml.
