✅ Changing ASPNETCORE_ENVIRONMENT causes broken site.

Hi all, I am wanting to test our ASP .NET CORE App coupled with Blazor Wasm in production. So I changed ASPNETCORE_ENVIRONMENT to "Production", and altered Program.cs to work with it:

// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();

    using (var scope = app.Services.CreateScope())
    { // Require a DbContext from the service provider and seed the database.
        var dbContext = scope.ServiceProvider.GetRequiredService<ApplicationDbContext>();
        Seeder seeder = new(dbContext);
        await seeder.Seed();
    }
}
else
{
    using (var scope = app.Services.CreateScope())
    { // Require a DbContext from the service provider and seed the database.
        var dbContext = scope.ServiceProvider.GetRequiredService<ApplicationDbContext>();
        Seeder seeder = new(dbContext);
        await seeder.SeedProd();
    }
}

app.UseHttpsRedirection();

app.UseBlazorFrameworkFiles();
app.UseStaticFiles();
app.UseRouting();
app.UseAuthentication();
app.UseAuthorization(); 

app.MapControllers();
app.MapFallbackToFile("index.html");



app.Run();

// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();

    using (var scope = app.Services.CreateScope())
    { // Require a DbContext from the service provider and seed the database.
        var dbContext = scope.ServiceProvider.GetRequiredService<ApplicationDbContext>();
        Seeder seeder = new(dbContext);
        await seeder.Seed();
    }
}
else
{
    using (var scope = app.Services.CreateScope())
    { // Require a DbContext from the service provider and seed the database.
        var dbContext = scope.ServiceProvider.GetRequiredService<ApplicationDbContext>();
        Seeder seeder = new(dbContext);
        await seeder.SeedProd();
    }
}

app.UseHttpsRedirection();

app.UseBlazorFrameworkFiles();
app.UseStaticFiles();
app.UseRouting();
app.UseAuthentication();
app.UseAuthorization(); 

app.MapControllers();
app.MapFallbackToFile("index.html");



app.Run();

Now I only get a white page and it is showing 3 warnings:

warn: Microsoft.AspNetCore.StaticFiles.StaticFileMiddleware[16]
      The WebRootPath was not found: MyPathHere Static files may be unavailable.

How can I fix this?

When ASPNETCORE_ENVIRONMENT changed to anything but "Development" -...

Maybe just try the example: https://github.com/HTD/BlazorProfiles This is a demo Blazor application (default). I created 2 custom application profiles: Development and Production. Both should be

Yay! I don't remember. Something like "blazor empty page ASPNETCORE_ENVIRONMENT"
