There's a secret error in your secret code. You'll need to fix that error.

At a guess, you're mixing constructs from .NET Core 2.x and .NET Core 3. You can't simply cast an IWebHostEnvironment[^] to an IHostingEnvironment[^], or vice-versa.

1 solution

In ASP.NET Core 3 use following for Rotativa configuration:
RotativaConfiguration.Setup(env.WebRootPath, "Rotativa");
Add a new folder inside "wwwroot" with name “Rotativa” and inside this folder keep the wkhtmltoimage.exe and wkhtmltopdf.exe files.

Compiler complains that string cannot to convert to IHostingEnvironment. Is there an updated version that takes those 2 string parameters?
