As per the compatibility matrix, currently Nintex Automation (5.8) and Nintex Automation K2 (5.9, and 5.9.1) are the only supported versions that support .NET 8.0.
According to Microsoft, official support for .NET 8 is ending on November 10, 2026.
Instructions
We are releasing fix packs for supported K2 versions to upgrade support from .NET 8.0 to .NET 10.0. When these fix packs are released, this article will be updated to include the necessary fix pack level.
This will be only for supported versions, so if you are on an older K2 version and require .NET 10 support, make a plan to upgrade today.
When in doubt. please refer to our compatibility matrix (https://help.nintex.com/en-US/platform/K2Support/ProductCompatibilityMatrix.htm#.NET_Core) on the latest product compatibility. Any updates to .NET compatibility will be reflected in the compatibility matrix, as well as supported upgrade paths.
