Singularize method not found

Question

For the last months I didn't had any problem but since few days my application doesn't start. I've spent many hours trying my best to finally come with this error :

System.MissingMethodException : 'Méthode introuvable : 'System.String Humanizer.InflectorExtensions.Singularize(System.String, Boolean)'.'

The problem is related with the SQLKata NuGet extension but i don't have any ideas on what to do. I've made a few tries like :

• Uninstalling and reinstalling the package
• Repair VS
• Rewrite a part of the code that was working before
• Looking on many places to find a solution

Answer 1

Are you sure your issue is relating to SQLKata and not Humanizer?

The inflector method for Singularise is found here on the Humanizer GitHub page documentation. https://github.com/Humanizr/Humanizer#inflector-methods

If this is indeed what you are looking for, you should reinstall the Humanizer NuGet or download from their GitHub and add direct to your project.

You can check if the assembly is within your project by checking the bin folder for Humanizer.dll

Answer 2

Upgrading both SqlKata and SqlKata.Execution to version 2.3.2 worked for me.

Answer 3

The Humanizer interface was changed in this commit; https://github.com/Humanizr/Humanizer/commit/fc887b302773472f889e2908f79d7325229f9929

Which breaks the compatibility with the latest SqlKata (v2.2.0). Downgrading Humanizer to v2.7.9 worked for me.
