回答1:

Remove existing Rotativa.AspNetCore from Nuget packages then install the beta version:

Install-Package Rotativa.AspNetCore -Version 1.2.0-beta

This has the overload method in it that also works with IWebHostingEnvironment

After installing configure in Configure method as:

RotativaConfiguration.Setup(env.WebRootPath, "Rotativa");

Im find a solution like this in statup.cs in configure function add env2 and obsolute

        [Obsolete]
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env, Microsoft.AspNetCore.Hosting.IHostingEnvironment env2)

and change this like

   RotativaConfiguration.Setup(env2);

its working now but ıts bad solution if you know better one pls describe it.

Works on versions 3.0 and 3.1

// Rotary configuration 
// This is for the rotating to use the files in the Rotating folder
RotativaConfiguration.Setup (env.ContentRootPath, "Rotativa");
