For serving images,js and css in asp.net core MVC application ,I use app.UseStaticFiles method and serve from a physical location.

app.UseStaticFiles(new StaticFileOptions()
                {
                    FileProvider = new PhysicalFileProvider("c://staticfiles"),
                    RequestPath = new PathString("/cdn"),
                    ServeUnknownFileTypes=true
                });

but now I want to use Azure Blob storage containers to serve those file . I add Azure.Storage.Blobs nuget package in my application but did not found any FileProvider class for Azure Blob Storage .

How do I do this?

Thanks.

What I have tried:

app.UseStaticFiles(new StaticFileOptions()
                {
                    FileProvider = new PhysicalFileProvider("c://staticfiles"),
                    RequestPath = new PathString("/cdn"),
                    ServeUnknownFileTypes=true
                });
