Extending Dynamics 365 for Operations


Dynamics 365 for Operations has great support for implementing pure add-on solutions. A pure add-on solution is extending the existing functionality using extension points in a non-intrusive manner.

 

In the Dynamics AX era implementing non-intrusive solutions was near impossible. My decade old Channel 9 video on Smart customizations is recommending being as little intrusive as possible.

That is still good advice; as it turns out we can now be significantly less intrusive. A lot of new extensibility features has been added. This series of blog posts will explore these.

Why it matters?

When a solution is implemented using extension points only, then the solution’s cost of maintenance drops significantly:

  • The code conflicts that are typically experienced during code upgrade seize to exists.
  • The compilation time is reduced by magnitudes,
  • The package size is reduced.

Some terminology

A good citizen is referring to a well-behaved extension, that can live side-by-side with other extensions sharing the extension points. The opposite is a bully, they claim the extension point for themselves, and are at risk of colliding with other solutions.
