Visual Studio 2019 error: Failed to create an editor. Value cannot be null. Parameter name password.

Good morning to everyone!

Yesterday I installed Visual Studio 2019 Community on my PC, just to keep up with the times…

I opened a solution containing a Sql Server database project, and opening any project file I received the following error:

“Failed to create an editor. Value cannot be null. Parameter name password”

You can see the screenshot below.

How to solve this?

In the project directory, there is a file with extension “.sqlproj.user”.

Close Visual Studio, delete this file and then run Visual Studio again.

Now you will be able to open files under your database project.

Bye Bye 🙂
