They are then stored as a DynamicMethod within the current process. Pretty wicked stuff! This expression can then be compiled and invoked. This means that the compiler visits each node into the AST and compiles it into a LINQ expression tree. ![]() The method accepts an AST and outputs an Expression. After some perusing around the members within this class I ran into the Compile method. This means that the compiler tells the AST how it should be traversed. Adam Driscoll writes about these changes: The Compiler class is an ICustomAstVisitor. The parser has been rewritten, and the API is now public. PowerShell 3 uses the Dynamic Language Runtime, which should provide substantial performance improvements over PowerShell 2. ![]() ![]() Similarly, more robust sessions allow better recovery from network interruptions and shutdowns, so that tasks can continue running where they left off. This feature takes advantage of functionality in Windows Workflow Foundation (WWF) PowerShell scripts are translated into WWF code to create the workflows. Workflows can be used to create parallelized, long-running tasks that are capable of being interrupted and recovering even when a machine is shut down.
