In case it's helpful, here are copies of the code files: Program.cs using Microsoft.Data.Sqlite;
using Microsoft.EntityFrameworkCore;
using SqliteJsonTest;
await using var conn = new SqliteConnection(new SqliteConnectionStringBuilder
{
DataSource = ":memory:",
}.ConnectionString);
await conn.OpenAsync();
await using var db = new WidgetContext(new DbContextOptionsBuilder<WidgetContext>().UseSqlite(conn).Options);
await db.Database.EnsureCreatedAsync();
var widget = await db.Widgets.SingleAsync();WidgetContext.cs using Microsoft.EntityFrameworkCore;
namespace SqliteJsonTest;
internal sealed class WidgetContext : DbContext
{
public DbSet<Widget> Widgets { get; set; }
public WidgetContext(DbContextOptions options) : base(options)
{
}
}Widget.cs using System.Text.Json;
namespace SqliteJsonTest;
internal sealed class Widget
{
public long Id { get; set; }
public JsonElement Metadata { get; set; }
