The IFileProvider is PhysicalFileProvider because only its constructor accepts only one parameter that is for the root directory. https://docs.microsoft.com/en-us/dotnet/api/microsoft.extensions.fileproviders.physicalfileprovider.-ctor?view=dotnet-plat-ext-3.1#Microsoft_Extensions_FileProviders_PhysicalFileProvider__ctor_System_String_

IFileProvider (as it is dependency for a corresponding controller) PhysicalFileProvider (have no idea why since CosmosDB used for event data storage) IHostingEnvironment (for getting current root path) DirectoryInfo (return new points that and object is constructed there with a path as its parameter)

To know why this is the answer I looked into EventsController and I see that IFileProvider is a dependency for the controller. So it makes sense to pass it as a dependency in the pipeline in Startup.cs. Return type of the method is PhysicalFileProvider instance so second parameter is PhysicalFileProvider.
