TypeLoadException: 'Volo.Abp.LanguageManagement.Domain, Version=2.9.0.0' does not have an implementation. #638

Need help on this error. I suspect a module is the wrong version but not sure.

TypeLoadException: Method 'get_ExtraProperties' in type 'Volo.Abp.LanguageManagement.Language' from assembly 'Volo.Abp.LanguageManagement.Domain, Version=2.9.0.0' does not have an implementation.

The program stops at services.AddApplication<EducatePlusWebModule>();

public class Startup { public void ConfigureServices(IServiceCollection services) { services.AddApplication<EducatePlusWebModule>(); }
