Blazor WebAssembly App Loads Configuration Values After Executing Methods Resulting in Null's Initialy then it will return with correct values.
I followed Microsoft documentation.
Appseting File:
wwwroot/appsettings.json
My Component.razor:
@page "/"
<h1>Configuration example</h1>
<p>Message: @Configuration["message"]</p>
@code {
protected override async Task OnParametersSetAsync()
{
await trying to read Configuration["Message"];
}
}
My Program.cs File:
public class Program
{
public static async Task Main(string[] args)
{
var builder = WebAssemblyHostBuilder.CreateDefault(args);
builder.RootComponents.Add<App>("app");
builder.Services.AddTransient(sp => new HttpClient { BaseAddress = new Uri(builder.HostEnvironment.BaseAddress) });
await builder.Build().RunAsync();
}
}
My _Imports.razor
@using System.Net.Http
@using System.Net.Http.Json
@using Microsoft.AspNetCore.Components.Forms
@using Microsoft.AspNetCore.Components.Routing
@using Microsoft.AspNetCore.Components.Web
@using Microsoft.AspNetCore.Components.WebAssembly.Http
@using Microsoft.Extensions.Configuration
@using Microsoft.JSInterop
@inject IConfiguration Configuration;
Note: Understand that I am getting the value's correctly but always null first then re-renders with correct values, i am using OnParametersSetAsync() as entry point, i understand OnParametersSetAsync() changes on every Parameter Change. but the Configuration Values should be constant not null first right?
