Integrating with .NET 8

[svallis]

First up thanks for the fantastic looking project, looks perfect for what I'm looking to do.

I'm trying to get things up and running in a brand new .NET 7 project and am hitting some issues with the database migrations. I might be missing something obvious here, so apologies if I am; but perhaps it's related to how I've approached getting things up and running. If nothing else it might help solidify some examples for your docs for the current .NET version.

I started with a new "ASP.NET Core Web App" template. Here's the startup/configuration code:

var builder = WebApplication.CreateBuilder(args);

var connectionString = builder.Configuration.GetConnectionString("DefaultConnection");
builder.Services.AddDbContext<ApplicationDbContext>(options => options.UseSqlServer(connectionString));
builder.Services.AddDatabaseDeveloperPageExceptionFilter();
builder.Services.AddDefaultIdentity<IdentityUser>(options => options.SignIn.RequireConfirmedAccount = true)
    .AddEntityFrameworkStores<ApplicationDbContext>();

builder.Configuration.AddPineBlogEntityFrameworkCoreConfiguration(reloadOnChange: true);
builder.Services.AddPineBlog(builder.Configuration);

builder.Services.AddRazorPages();

var app = builder.Build();

if (app.Environment.IsDevelopment())
{
    app.UseMigrationsEndPoint();
}
else
{
    app.UseExceptionHandler("/error");
    app.UseHsts();
}

app.UseHttpsRedirection();
app.UseStaticFiles();

app.UseRouting();

app.UseAuthentication();
app.UseAuthorization();

app.MapRazorPages();
app.MapControllers();

app.Run();

Here is the appsettings.json I'm using:

{
  "ConnectionStrings": {
    "DefaultConnection": "Data Source=localhost;Initial Catalog=Blog;Integrated Security=True;MultipleActiveResultSets=True;TrustServerCertificate=True"
  },
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft.AspNetCore": "Warning"
    }
  },
  "PineBlogOptions": {
    "Title": "PineBlog",
    "Description": "A blogging engine based on ASP.NET Core MVC Razor Pages and Entity Framework Core",
    "CoverUrl": "/images/woods.gif",
    "CoverCaption": "Battle background for the Misty Woods in the game Shadows of Adam by Tim Wendorf",
    "CoverLink": "http://pixeljoint.com/pixelart/94359.htm",
    "ItemsPerPage": 5,
    "EnableSearch": false,
    "CreateAndSeedDatabases": true,
    "ConnectionStringName": "DefaultConnection",
    "AzureStorageConnectionString": "UseDevelopmentStorage=true",
    "AzureStorageBlobContainerName": "pineblog",
    "FileBaseUrl": "http://127.0.0.1:10000/devstoreaccount1"
  },
  "AllowedHosts": "*"
}

The issues occur when trying to run the migrations for the database. This running against a full SQL Server Developer instance installed on the development machine. Here's the log from the migrations, where the identity context works fine but the blog context fails. The blog context takes ~5 seconds to fail which feels like a timeout, which doesn't make a lot of sense for a local connection.

PS C:\Development\Blog> dotnet ef database update --context ApplicationDbContext

New development started, will skip support for .NET 7 and go directly to .NET 8.
