Investigating to publish angular app with Api in Azure takes more time, Following issue occurred and trying to resolve the issue with the following mentioned ways.
Issue Occurred:
System.InvalidOperationException: The SPA default page middleware could not return the default page '/index.html' because it was not found, and no other middleware handled the request. Your application is running in Production mode, so make sure it has been published, or that you have built your SPA manually. Alternatively you may wish to switch to the Development environment.
Tried Following ways: https://github.com/aspnet/JavaScriptServices/issues/1729 https://github.com/aspnet/JavaScriptServices/issues/1514 https://medium.com/@levifuller/building-an-angular-application-with-asp-net-core-in-visual-studio-2017-visualized-f4b163830eaa

Thanks
Hi christophedemey,
Resolved this issue by comparing existing Angular Asp net core template, I did following code changes. In csproj file:
<TypeScriptCompileBlocked>true</TypeScriptCompileBlocked>
<TypeScriptToolsVersion>Latest</TypeScriptToolsVersion>
<IsPackable>false</IsPackable>
<SpaRoot>ClientApp\</SpaRoot>
<DefaultItemExcludes>$(DefaultItemExcludes);$(SpaRoot)node_modules\**</DefaultItemExcludes>
<!-- Set this to true if you enable server-side prerendering -->
<BuildServerSideRenderer>false</BuildServerSideRenderer>
<UserSecretsId>baa2f579-d2a7-4eb4-89fb-1c171b2e2482</UserSecretsId>

<ItemGroup>

In Startup.cs
services.AddSpaStaticFiles(configuration =>
{
configuration.RootPath = "ClientApp/dist";
});
app.UseSpa(spa =>
{
spa.Options.SourcePath = "ClientApp";
if (env.IsDevelopment())
{
spa.UseAngularCliServer(npmScript: "start");
}
});
In Angular Package.json
"options": {
"outputPath": "dist",
Now issue is invoking REST Api from post man returning Angular page (working locally by not published), do you have idea on this?
Thanks, Sathish
Rest API working but seeding not working, investigating on this.
Issue is in Seeding not in Rest API invocation.
Commit Details: 80bd90629fca066a8e988ba0122e9cd8d284af68
Seeding also working now.
Need to investigate to publish Angular with Web Api in Azure.
