Could you paste in your AppHost Program.cs?

[v-yuwzh]

@vicperdana, in solution "eShopLite", there is no AppHost project, so I provide program.cs in Products as below:

using Microsoft.EntityFrameworkCore;
using Products.Data;
using Products.Endpoints;

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddDbContext<ProductDataContext>(options =>
    options.UseSqlite(builder.Configuration.GetConnectionString("ProductsContext") ?? throw new InvalidOperationException("Connection string 'ProductsContext' not found.")));

// Add services to the container.
var app = builder.Build();

// Configure the HTTP request pipeline.
app.MapProductEndpoints();

app.UseStaticFiles();

app.CreateDbIfNotExists();

app.Run();

provide Program.cs in Store as below:

using Store.Components;
using Store.Services;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddSingleton<ProductService>();
builder.Services.AddHttpClient<ProductService>(c =>
{
    var url = builder.Configuration["ProductEndpoint"] ?? throw new InvalidOperationException("ProductEndpoint is not set");

    c.BaseAddress = new(url);
});

// Add services to the container.
builder.Services.AddRazorComponents()
    .AddInteractiveServerComponents();

var app = builder.Build();

// Configure the HTTP request pipeline.
if (!app.Environment.IsDevelopment())
{
    app.UseExceptionHandler("/Error", createScopeForErrors: true);
    // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
    app.UseHsts();
}

app.UseHttpsRedirection();

app.UseStaticFiles();
app.UseAntiforgery();

app.MapRazorComponents<App>()
    .AddInteractiveServerRenderMode();

app.Run();

[vicperdana]

This doesn't seem related to Aspire, but to run this successfully, you'll need to ensure that the applicationUrl in Products launchSettings.json is defined exactly the same per appSettings.json ProductEndpoint in Store.

The default config seems to point to different address http://localhost:5200 vs http://localhost:5228

[v-yuwzh]

@vicperdana , After I ensure that the applicationUrl in ProductslaunchSettings.json is defined exactly the same per appSetting.json ProductEndpoint in Store.

this issue works well, first thanks for you suggestion, for the user, need change applicationUrl value is unfriendly to the user after clone this solution, could you help to update this solution or do you know who is owner for this solution? Thanks in advance.

[vicperdana]

I am not aware - perhaps raise an issue here?
