Added new properties to ToDo class and
`public class Todo
{
[Key]
public int Id { get; set; }

    public string Title { get; set; }

    public bool IsComplete { get; set; }

    public string Property1 { get; set; }
    public string Property2 { get; set; }
    public string Property3 { get; set; }
    public string Property4 { get; set; }
    public string Property5 { get; set; }
    public string Property6 { get; set; }
}`

And modified ClientSideDbContext.cs
`protected override void OnModelCreating(ModelBuilder modelBuilder)
{
base.OnModelCreating(modelBuilder);

        modelBuilder.Entity<Todo>().HasData(new Todo[]
        {
            new Todo { Id = 1, Title = "Todo 1", IsComplete = false, Property1 = "p1", Property2 = "p2", Property3 = "p3", Property4 = "p4", Property5 = "p5", Property6 = "p6"},
            new Todo { Id = 2, Title = "Todo 2", IsComplete = false, Property1 = "p1", Property2 = "p2", Property3 = "p3", Property4 = "p4", Property5 = "p5", Property6 = "p6" },
            new Todo { Id = 3, Title = "Todo 3", IsComplete = false, Property1 = "p1", Property2 = "p2", Property3 = "p3", Property4 = "p4", Property5 = "p5", Property6 = "p6" },
        });
    }`

The Exception is:
An exception occurred while iterating over the results of a query for context type 'BlazorWasmSQLiteTest.ClientSideDbContext'.
Microsoft.Data.Sqlite.SqliteException (0x80004005): SQLite Error 1: 'no such column: t.Property1'.

I have to manually delete the IndexedDB.SqliteStorage using F12 then reload the page, only then application is running fine and no more EF exception.
please advise, why does this happen whenever I added new properties?

thank you
