Here is a handy wallchart that condenses the information contained in our article 'The Visual LINQ Lexicon' even further, but which adds some more technical specs that allow you, for example, to see at a glance which operators use deferred execution and which use immediate execution. You can use it to see what operators use lambda syntax and which ones are available in query syntax. You can see all the other key properties of all the LINQ operators, even including even how much of a sequence a given operator actually consumes.
