RazorRuntimeCompilation fails when a non-managed dll is part of the project.

[Buildstarted]

Describe the bug

Whenever a non-managed dll is included in the bin folder during debug RazorRuntimeCompilation fails with the following error: Metadata file '...gsdll64.dll' could not be opened -- PE image doesn't contain managed metadata.

To Reproduce

New project with nuget packages

Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation
Ghostscript

Create a simple controller with a razor page. Load the page in debug mode, modify the razor page, and refresh.

Startup:

        public void ConfigureServices(IServiceCollection services)
        {
            services.AddControllersWithViews().AddRazorRuntimeCompilation();
        }

        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            app.UseRouting();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllers();
            });
        }
