[Solved] Visual Studio 2026 “VSCommonPackage” Error After D365FO 10.0.49 Update

Hello,

With the release of Dynamics 365 Finance & Operations (D365FO) 10.0.49, developers are required to move to the newer Visual Studio 2026 development environment. While the upgrade itself is generally straightforward, some developers may encounter the following warning when launching Visual Studio:

"The 'VSCommonPackage' package did not load correctly."

The VSCommonPackage is a core Visual Studio component responsible for loading common services and functionality used by Visual Studio extensions and development workloads.

Solution: 

1. Close Visual Studio and delete the following folder:

C:\Users\<User>\AppData\Local\Microsoft\VisualStudio\18.0_xxxxx\ComponentModelCache

2. Launch Visual Studio in Safe Mode, Open a command prompt and execute: devenv /safemode

3. Reset Visual Studio Settings, Execute: devenv /resetsettings. This restores the default Visual Studio configuration.

Now try to reopen VS and you should be able to use it without any issue now. 

In case you are still facing issues, worth to check my earlier post on similar error,
