Language Service and IntelliSense

The Language Service reads from assemblies referenced by your project to provide IntelliSense and error reporting while you are editing code. The Language Service is unable to reread an assembly that has changed. So if you have a project with references to other projects or assemblies which change, the Intellisense and error reporting can become inaccurate. Currently, the only way to refresh this information is to close down the IDE and restart it.
