I have a problem to use web api Owin with ninject. When I try to use my web api , it was this error, and I can not fix this problem , I've tried many ways , none of which revolved my problem.
This error occurs when I boot my application
Error activating ModelValidatorProvider using binding from ModelValidatorProvider to
NinjectDefaultModelValidatorProvider
A cyclical dependency was detected between the constructors of two services.
Activation path:
3) Injection of dependency ModelValidatorProvider into parameter defaultModelValidatorProviders of constructor of type DefaultModelValidatorProviders
2) Injection of dependency DefaultModelValidatorProviders into parameter defaultModelValidatorProviders of constructor of type NinjectDefaultModelValidatorProvider
1) Request for ModelValidatorProvider
Suggestions:
1) Ensure that you have not declared a dependency for ModelValidatorProvider on any implementations of the service.
2) Consider combining the services into a single one to remove the cycle.
3) Use property injection instead of constructor injection, and implement IInitializable
if you need initialization logic to be run after property values have been injected
