Today, I fixed a bug where session cookies were not being persisted in an ASP.Net Core Razor Pages application.
The answer was in the documentation.
To quote that page:
The order of middleware is important. Call
UseSession
afterUseRouting
and beforeUseEndpoints
So my code which did work in the past, but probably before endpoint routing was introduced was this:
app.UseSession();
app.UseRouting();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
endpoints.MapRazorPages();
});
And the fix was to move UseSession
below UseRouting
app.UseRouting();
app.UseSession();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
endpoints.MapRazorPages();
});
Success 🎉
