visual studio 2019 open solution file incompatible

SSIS is a seperate extension now in Visual Studio 2019. You can install that extension in Visual Studio market place. Choose Online tab and search for "SQL Server Integration Services Projects".Hope it can help your problem

Today I faced this issue,

Cause

The reason for issue is, I saw a yellow bg notification at the top of IDE showing performance issue , with option to "disable this" to improve the performance. I chose disable, later next day when I opened the project, It showed the project is not compatible. I did Repair SSIS, Uninstall and Reinstall SSIS, and also updated the SSIS to latest version. None of these 3 ways resolved the issue.

Solution

But, I found Manage Extension submenu item under Extension menu, Under installed tab, SSIS extension was in disabled status. I reverted to Enabled status. Sample screenshot of the same for reference is here. If it disabled, simply enable it. Then restart VS with SSIS project.

• 1.Extensions -> Microsoft Reporting Service Project
• 2.and then close visual studio
• 3.VSIX installer will complete automatically
• 4.If your project unloaded, right click on project and reload
