Read file from wwwroot in Blazor web app

I have a JSON file in wwwroot/Resources/form-input-list.json In my razor file I wanna do this:

@code {
    private Field[]? fields;

    protected override async Task OnInitializedAsync()
    { 
        var json = await Http.GetFromJsonAsync<FormData>("Resources/form-input-list.json");
         fields = json?.fields;
    }

    private class FormData
    {
        public Metadata metadata { get; set; }
        public Field[] fields { get; set; }
    }

    private class Metadata
    {
        public int version { get; set; }
        public string project { get; set; }
    }

    private class Field
    {
        public string type { get; set; }
        public string id { get; set; }
        public string name { get; set; }
        public string labelText { get; set; }
        public string helperText { get; set; }
        public bool isRequired { get; set; }
        public Item[] items { get; set; }
        public string placeholderText { get; set; }
    }

    private class Item
    {
        public string id { get; set; }
        public object value { get; set; }
        public string labelText { get; set; }
    }
}

@code {
    private Field[]? fields;

    protected override async Task OnInitializedAsync()
    { 
        var json = await Http.GetFromJsonAsync<FormData>("Resources/form-input-list.json");
         fields = json?.fields;
    }

    private class FormData
    {
        public Metadata metadata { get; set; }
        public Field[] fields { get; set; }
    }

    private class Metadata
    {
        public int version { get; set; }
        public string project { get; set; }
    }

    private class Field
    {
        public string type { get; set; }
        public string id { get; set; }
        public string name { get; set; }
        public string labelText { get; set; }
        public string helperText { get; set; }
        public bool isRequired { get; set; }
        public Item[] items { get; set; }
        public string placeholderText { get; set; }
    }

    private class Item
    {
        public string id { get; set; }
        public object value { get; set; }
        public string labelText { get; set; }
    }
}

And in my program.cs I have defined it like so:

using nhs_frontend_csharp.frontend.Components;

var builder = WebApplication.CreateBuilder(args);

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

builder.Services.AddHttpClient();
builder.Services.AddScoped(sp => new HttpClient { BaseAddress = new Uri("https://localhost:8081/") });

var app = builder.Build();

// Configure the HTTP request pipeline.
if (!app.Environment.IsDevelopment())
{
    app.UseExceptionHandler("/Error", createScopeForErrors: true);
}

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

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

app.Run();

using nhs_frontend_csharp.frontend.Components;

var builder = WebApplication.CreateBuilder(args);

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

builder.Services.AddHttpClient();
builder.Services.AddScoped(sp => new HttpClient { BaseAddress = new Uri("https://localhost:8081/") });

var app = builder.Build();

// Configure the HTTP request pipeline.
if (!app.Environment.IsDevelopment())
{
    app.UseExceptionHandler("/Error", createScopeForErrors: true);
}

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

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

app.Run();

Yet I keep receiving HTTP Exceptions.

Visual Studio integration with Docker Compose not functioning as expected.

Hello, I have on solution level a docker-compose file which I use to containerize my application. In Visual Studio I have because of this also a start button with Docker Compose. Yesterday I decided to make some changes in my Docker-compose file. Yet because of this I am unable to launch my project again.

The active launch profile Docker Compose is not valid. The services 'blob-storage' used in launch profile are not present in the docker compose files.

The active launch profile Docker Compose is not valid. The services 'blob-storage' used in launch profile are not present in the docker compose files.

When I click on this error message, Visual Studio redirects me to this file: Microsoft.VisualStudio.Docker.Compose.targets. I have tried to clean and rebuild the project but I have no clue on how to resolve this issue. Deleting this file is discouraged either.
