Optimize SSDT Composite Projects (Performance & Schema Compare)
When using Composite Database Projects (2 Projects / Reference as "Same Database") you will find one *.dbmdl Files in each Project folder and it seems that the referencing Project contains all Objects from the referenced Project, too (on the disk an in-memory as well).
If you use "Schema Compare" between the referencing Project and your Database, all non-changed Objects will be shown (not able to filter them out) and changed Objects could not be disabled.
Thank you for your suggestion! While we aim to respond to every suggestion, we are closing older ones that don’t have enough votes so newer ones from you can move to the top. If this suggestion is still important to you, feel free to open it again.

I would love to see improvements with Schema Compare and Composite Projects...
