ExecuteUpdateAsync not suported with SetProperty with Value Expression

[WaffleBuffer]

Hello,

i've been working with MockQueryable for a while now.
Recently i tried the new 9.0.0 version for EntityFramework and NSubstitute in XUnit and dotnet 9 because i have some projects which use ExecuteUpdateAsync.
I saw some PR to add support to ExecuteUpdate so the data in tests are actually updated (which is what i would like).

However when i tried to use it with SetProperty with Value Expression like this

public class Entity
{
    public DateTimeOffset Date { get; set; }
}

public class Test
{
    [Fact]
    public async Task Test1()
    {
        // Arrange
        var entity1 = new Entity
        {
            Date = new DateTimeOffset(2025, 10, 14, 00, 00, 00, TimeSpan.Zero),
        };
        var entity2 = new Entity
        {
            Date = new DateTimeOffset(2026, 10, 14, 00, 00, 00, TimeSpan.Zero),
        };
        List<Entity> entities = [entity1, entity2];
        var mockDbSet = entities.BuildMockDbSet();

        // Act
        await mockDbSet.ExecuteUpdateAsync(e =>
            e.SetProperty(e => e.Date, e => e.Date.AddYears(1))
        );

        // Assert
        Assert.Equal(new DateTimeOffset(2026, 10, 14, 00, 00, 00, TimeSpan.Zero), entity1.Date);
        Assert.Equal(new DateTimeOffset(2027, 10, 14, 00, 00, 00, TimeSpan.Zero), entity2.Date);
    }
}

I get this error

However if i change my test to use a SetProperty with a fixed value like this

// Act
        await mockDbSet.ExecuteUpdateAsync(e =>
            e.SetProperty(e => e.Date, new DateTimeOffset(2028, 10, 14, 00, 00, 00, TimeSpan.Zero))
        );

        // Assert
        Assert.Equal(new DateTimeOffset(2028, 10, 14, 00, 00, 00, TimeSpan.Zero), entity1.Date);
        Assert.Equal(new DateTimeOffset(2028, 10, 14, 00, 00, 00, TimeSpan.Zero), entity2.Date);

Then the test pass with no exception
