# Installing Decisions SDK with NuGet in Visual Studio

Version 8.9+ is built on [.NET 7](https://dotnet.microsoft.com/en-us/download/dotnet/7.0). Visit [Minor Version Update Guide](https://documentation.decisions.com/docs/minor-version-update-guide) for assistance on minor updates (E.g., Upgrading 8.6 to 8.9).

**Impact on Upgrades**

- Upgrades from versions before v7 require an "uninstall" ahead of installing v8
  - [Upgrades from v6 to v8](https://documentation.decisions.com/v8/docs/upgrading-decisions-v6-to-v8)
  - [Upgrades from v7 to v8](https://documentation.decisions.com/v8/docs/upgrading-decisions-v7-to-v8)
  - [Upgrades from v6 to v8 (Multi-tenancy)](https://documentation.decisions.com/v8/docs/upgrading-a-v6-multi-tenancy-to-v8)
- ALL **Custom** **Libraries** will need to be recompiled.
- Custom assemblies will need to be rewritten.
- Modules may require design refactoring or downloading newer versions.
- Running multiple versions with the same database is not supported.
- LESS files from prior versions are not directly compatible with v8

The Decisions SDK can be installed as a NuGet package using Visual Studio.
