The Metro program is for valued partners of Microsoft and requires an invitation to join. Not all ISVs will be able to join Metro. If you are interested in joining the Metro program, please contact your Microsoft sponsor or email metrohlp@microsoft.com if you do not have a sponsor. Once you get an invitation, the signup process is as follows: 1. Log into http://www.discovermetro.net/
You will need to authenticate with your Live ID account to gain access to the Metro website. 2. Profile your application
It is important to profile your application in Metro. There are a number of internal Microsoft staff that rely on an accurate description of your application profile to identify internal and external marketing opportunities or other Metro services that might be of value to you. Profiling your application will take about 5 minutes as you fill out a form describing your application, its current stage, and which Microsoft technologies it uses. 3. Enroll in tracks that are of interest for your company
There are a number of tracks in Metro, and each track contains a number of subtracks, depending on the technology. Simply select the ones that are of interest to you and hit the Register button. Please note that once you are in Metro, you are not restricted to one technology, nor are you restricted to tracks with technologies specific to your product. For example, your application may be a desktop application, but you are still free to join the Web UX - Silverlight track if you are interested in learning more about Silverlight. 4. Explore the content, support, forums, and events profiles in the portal.
Each track has different information. All tracks have support and forums. There is a lot of very useful information and events in each of the track. Come back to the site often and review current events and announcements. |
