Description:
On fresh installations of Microsoft Visual Studio Community 2019 (Version 16.10.0) and MySQL for Visual Studio 1.2.9, whenever I try to create a new MySQL script I get "The 'MySQL for Visual Studio 1.2.9' 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 ...\ActivityLog.xml'. Restarting Visual Studio could help resolve this issue."
I tried restarting and reinstalling the MySQL extension, with no success.
Below an extract of the ActivityLog.xml.
