Introduction to Publisher: Create a solution publisher in Microsoft Dynamics CRM

Each solution requires a publisher, and publisher contains prefix like “new_” The solution publisher controls how managed solutions can be updated.

Many solutions can be associated with a single solution publisher. Each organization will have a solution publisher called “Default Publisher" for your organization.

Create a solution publisher:

Path: Dynamics 365 > Settings > Customizations > Publishers (Create, modify or delete a solution publisher.)

Click on New and enter the following details:

1. Display Name
2. Name (by default small case of display name; can be changed)
3. Prefix (as you choose)
4. Optional fields can be filled/ ignored.
5. Click on Save / Save and Close button and your publisher is ready to use. 

Note:

1. Any new component created associated with custom publisher will start with publisher prefix like demo_xxxx.
2. Once publisher is created you cannot change Name (logical name) of publisher whereas Display name and prefix can be editable.
3. If you change prefix (like from demo to demo1) your existing created custom component will be available and new component will start from demo1_xxxx.
