How to use with top-lavel statements

[ibiza240]

Hi, Program.cs can be written differently with the latest C# version. Is it possible to use this package in a Program.cs written in top-level statements?

My Program.cs looks like below and I don't see where to insert the magic lines builder.Services .AddControllers(options => options.UseDateOnlyTimeOnlyStringConverters()).AddJsonOptions(options => options.UseDateOnlyTimeOnlyStringConverters());, since there is no call to a AddControllers method with this syntax.

var builder = WebApplication.CreateBuilder(args);
builder.Services.AddRazorPages();

var app = builder.Build();
if (!app.Environment.IsDevelopment())
{
    app.UseExceptionHandler("/Error");
    app.UseHsts();
}

app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseRouting();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
// **********
// TODO: I want to be able to serialize DateOnly in my API endpoints requests/responses
    endpoints.MapControllers(); // Map attribute-routed API controllers
// **********
    endpoints.MapRazorPages();// Map razor pages
});

app.Run();

Thanks!

Hi, does this work? After that DateOnly/TimeOnly conversions should work for everything (not only controllers)

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddRazorPages();
builder.Services 
    .AddControllers(options => options.UseDateOnlyTimeOnlyStringConverters())
    .AddJsonOptions(options => options.UseDateOnlyTimeOnlyStringConverters());

var app = builder.Build();
if (!app.Environment.IsDevelopment())
{
    app.UseExceptionHandler("/Error");
    app.UseHsts();
}

app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseRouting();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
    endpoints.MapControllers(); // Map attribute-routed API controllers
    endpoints.MapRazorPages();// Map razor pages
});

app.Run();

Hi and thanks for your answer!

This compiles, I put breakpoints and both options.UseDateOnlyTimeOnlyStringConverters() lines get hit, however I am getting this when calling my API endpoint which is returning an object containing a DateOnly property :

System.NotSupportedException: The type 'System.DateOnly' is not a supported dictionary key using converter of type 'DateOnlyTimeOnly.AspNet.Converters.DateOnlyJsonConverter'. The unsupported member type is located on type 'MyObjectWithDateOnly'. Path: $.
---> System.NotSupportedException: The type 'System.DateOnly' is not a supported dictionary key using converter of type 'DateOnlyTimeOnly.AspNet.Converters.DateOnlyJsonConverter'.

This is related to #10 (comment).
As it says: 'DateOnly' is not a supported dictionary key, I believe, this is System.Text.Json limitation (DateTime also not supported)

Hm, maybe DateTime is supported. Interesting. In any case, closing this as duplicate of #10. Discussion can continue there
