Got a new version of LinqtoCRM running, but it is not nearly as big an improvement as I had hoped. While Matt Warren’s posts proved a big boost, some of the stuff is not applicable to CRM (eg. constructing expression trees so they can be StringBuilded sequentially to SQL) and some of it I just have to think about some more.
Anyway, go get it while it’s hot.
Absolutely love LinqtoCRM. This is how easy access to CRM data should be.
I found out today that when I queried a field that had no value, in my case the purpose field in a list, it caused the following error which I “fixed” by making sure the field was populated.
Thank you again for such a great project.
