Make sure that the controller has a parameterless public constructor error
In Asp.net core web application, I have created "ArticleController" controller and it has a constructor as below :
private IBrandBoCached _brandBoCached;
private ITextBoxSeoNewBo _texboxseoBo;
public ArticleController( IBrandBoCached brandBoCached, ITextBoxSeoNewBo texboxseoBo)
{
this._brandBoCached = brandBoCached;
this._texboxseoBo = texboxseoBo;
}
After running this application I got an error that An error occurred when trying to create a controller of type 'ArticleController'. Make sure that the controller has a parameterless public constructor.
Note: I used the Unity container to init all service for the application.
Thank you for any suggestions.

Hello,
I also get the same error. This error occurs when declaring some interface service error in the Unity container. Please recheck all register interface services in Unity container. Maybe your code looks like as below, you will get this error :
container.RegisterType<ITextBoxSeoNewBo, ITextBoxSeoNewBo>();
You must change to :
container.RegisterType<ITextBoxSeoNewBo, TextBoxSeoNewBo>();
Your issue will be resolved.
I hope this suggests helpful to you.
