Export sql server registration info from VIsual St

Question

how can i export all my sql server registered in SQL Server Object Explorer?

I try Import and export settings but it dont save them

Answer 1

To my knowledge there's not a built-in mechanism that will save and restore these settings. The connection string data is saved in the registry under

 HKEY_CURRENT_USER\SOFTWARE\Microsoft\SSDT\ConnectionStrings

so you could perhaps export the settings from there.

The standard disclaimers about editing the registry being dangerous apply, as always.
