ASP.NET Core catch all routes for Web API and MVC are configured differently

With Web API (if you're using prefix "api" for all server-side controllers eg. Route("api/[controller"]):

app.Use(async (context, next) => 
{ 
    await next(); 
    var path = context.Request.Path.Value;

    if (!path.StartsWith("/api") && !Path.HasExtension(path)) 
    { 
        context.Request.Path = "/index.html"; 
        await next(); 
    } 
});            

app.UseStaticFiles();
app.UseDefaultFiles();

app.UseMvc();

With MVC (dotnet add package Microsoft.AspNetCore.SpaServices -Version x.y.z):

app.UseStaticFiles();
app.UseDefaultFiles();

app.UseMvc(routes => 
{ 
    routes.MapRoute( 
        name: "default", 
        template: "{controller=Home}/{action=Index}"); 

    routes.MapSpaFallbackRoute("spa", new { controller = "Home", action = "Index" }); 
});
