    I'm developing custom module. I have 2 model classes. Both of them derived from Content. 
    In this case I develope 2 manager classes ,they share the same data provider.
    However the content which backend  I access later will throw this error.

    The type String cannot be constructed. You must configure the container to supply this value.

    Hello Anton,

    This looks like you haven't registered your data provider in the configuration. This happens in the module configuration InitializeDefaultProviders as with the Products Module (ProductsConfig.cs). The whole module configuration is registered at the Initialize  method of the module -> Config.RegisterSection<ProductsConfig>();

    All the best,
