Looking to compare latest NPM features with previous versions of NPM?
The NPM new feature summary offers a comparison of new features and improvements offered with this release.
The NPM Summary home page intermittently loses connection. The following error occurs:
There was no endpoint listening at net.tcp://npmserver:17777/orion/core/businesslayer that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details
