## Software Frameworks

| Software | Compatible Versions |
| --- | --- |
| .NET Core | [8.0.7](https://dotnet.microsoft.com/en-us/download/dotnet/8.0) or higher |

:::note
Trouble: When upgrading from an earlier Test Manager version running on .NET 6 to a Test Manager version running on .NET 8, make sure that the compatibility level of the SQL Server is equal to or higher than 140. To check the compatibility level of your SQL Server, run this query:
```
SELECT compatibility_level FROM sys.databases WHERE name = '&lt;TestManagerDatabaseName&gt;';
```
If the compatibility level is lower than 140, run the following query:
```
ALTER DATABASE &lt;TestManagerDatabaseName&gt;
SET COMPATIBILITY_LEVEL = 140;
```

## Additional Settings
