Ran into an interesting issue today. Upon opening a new install of SQL Server 2019, I received the below error:
Version=18.104.22.168, Culture= neutral,
PublicKeyToken=89845dcd8080cc91’ package did not load correctly.
The problem may have been caused by a configuration change or by the installation of another extension. You can get more information by examining the file C:\Users\<username>\AppData\Roaming\Microsoft\AppEnv\1 5.0\ActivityLog.xml‘.
Restarting Visual Studio could help resolve this issue. Continue to show this error message?
UGH. Not helpful. I do what any reasonable IT person does – I google the error. Not super helpful either. I look back at the error message. Wait a minute. That version number looks odd. Since this is a new box, I look at what has been installed.
2 versions of SSMS? That in itself is not normally an issue, but it was the Preview version that gave me pause. Went to the authoritative voice – Microsoft – and said:
SSMS 19.0.1 is the latest general availability (GA) version. If you have a preview version of SSMS 19 installed, you should uninstall it before installing SSMS 19.0.1.
Ok. Fine. I’ll follow the rules. This once. I uninstalled both versions and then installed the most current version.
And just like that, I was back in business. Not even a reboot needed.
