This is an article continued from Developing a simple application using LINQ [Part 3]. In this part we will be looking at where we can use specific datatypes instead of using the "var" keyword, the Count(), Sum()and First() method. Continuing from the previous article, we create the third function. This function lets you take a closer look at different statistics PopulateProductStatistics() - In this function we will recover different statistics(products for reorder, types of products and total products) about the inventory.

Samsung has been supportive of Tizen from the get-go, but now it seems to be taking a rather major step. They are merging their home-grown mobile phone OS, bada with Tizen.With the convoluted road behind Tizen, its future had been uncertain till these announcements. Just recently, less than a week ago, the release of Tizen's source code and SDK was announced. This alleviated some of the worries about the project but was still far from being its salvation. Even though Intel is behind it, its previous failures to completely deliver MeeGo didn't help any.bada, is already a tried and tested framework, and combined with Tizen it offers a complete package. There were also rumours recently of bada being open sources, and this -- although not the same thing-- goes a long way in...
