QueryExpression vs. FetchXml CRM2011

Question

Answer 1

I would advocate in favor of FetchXML because I can use it in my JavaScript or C# code, unlike LINQ or QueryExpression...therefore one less thing to learn and maintain. As for stuff like Intellisense, there is a great tool that plugs into XrmToolbox called FetchXML Builder that is much more sophisticated in designing complex queries than you will ever see using Advanced Find. I have been using it now for a month for a CRM Online client and it is as close to using SQL as you can get in this environment. It can also generate QueryExpression code for me. I have turned over this tool to my business analysts and they are going to town using it to make sophisticated data sets for the dashboard - a big win for the clients.

I do lament the loss of detecting errors with early binding, but I enjoy
