DELETE FROM <table name> does not work as expected in EF Core when using the Microsoft.Data.Sqlite driver

To Reproduce

Call context.Database.ExecuteSqlInterpolated($"DELETE FROM {tableName}") or call context.Database.ExecuteSqlRaw("DELETE FROM {0}", tableName).

using System;
using Microsoft.EntityFrameworkCore;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.Hosting;
using Microsoft.Extensions.Logging;

public class Program
{
    public static void Main(string[] args)
    {
        var host = CreateHostBuilder(args).Build();
        
        using (var scope = host.Services.CreateScope())
        {
            var services = scope.ServiceProvider;

            try
            {
                var context = services.GetRequiredService<ApplicationContext>();
                DbInitializer.Initialize(context);
            }
            catch (Exception e)
            {
                var logger = services.GetRequiredService<ILogger<Program>>();
                logger.LogError(e, "An error occurred while seeding the database.");
            }
        }

        host.Run();
    }

    public static IHostBuilder CreateHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args)
            .UseWindowsService()
            .ConfigureServices((hostContext, services) =>
            {
                services.AddDbContext<ApplicationContext>(options =>
                    options.UseSqlite(hostContext.Configuration.GetConnectionString("DefaultConnection")));
            });
}

using Microsoft.EntityFrameworkCore;

public class ApplicationContext : DbContext
{
    public ApplicationContext(DbContextOptions<ApplicationContext> options)
        : base(options)
    {
    }
    
    public DbSet<Post> Posts { get; set; }
}

using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;

public class Post
{
    [Key]
    public int Id { get; set; }
    [Required]
    public string Title { get; set; }
}

using Microsoft.EntityFrameworkCore;

public static class DbInitializer
{
    public static void Initialize(ApplicationContext context)
    {
        context.Database.EnsureCreated();

        var entity = context.Model.FindEntityType(typeof(Post));

        if (entity != null)
        {
            var tableName = entity.GetTableName();

            context.Database.ExecuteSqlInterpolated($"DELETE FROM {tableName}");
        }
    }
}

fail: Microsoft.EntityFrameworkCore.Database.Command[20102]
      Failed executing DbCommand (1ms) [Parameters=[@p0='?' (Size = 5)], CommandType='Text', CommandTimeout='30']
      DELETE FROM @p0

      An error occurred while seeding the database.

This does not work either:

context.Database.ExecuteSqlRaw("DELETE FROM {0}", tableName);

However this does:

context.Database.ExecuteSqlRaw("DELETE FROM Posts");

Use string concatenation. SQLite doesn’t support parameter reference tokens in that part of the SQL.

It’s a SQL syntax error. We don’t parse SQL in EF Core or ADO.NET so that super unhelpful error coming directly from SQLite is the best we can do. Their errors are notoriously vague and unhelpful ☹️
