Concurrency issue with property initializers

[jorgeparavicini]

We have various applications, each with multiple ClassDataSources. Some also reuse the same data source, which should reuse the same instance. To illustrate, we have this example Application:

public sealed class ApplicationTestHost : ITestHost
{
    [ClassDataSource<MinioContainer>(Shared = SharedType.PerTestSession)]
    public required MinioContainer Minio { get; init; }

    [ClassDataSource<MongoDbContainer>(Shared = SharedType.PerTestSession)]
    public required MongoDbContainer MongoDb { get; init; }

    [ClassDataSource<MailhogContainer>(Shared = SharedType.PerTestSession)]
    public required MailhogContainer Mailhog { get; init; }

    [ClassDataSource<RedisContainer>(Shared = SharedType.PerTestSession)]
    public required RedisContainer Redis { get; init; }

    [ClassDataSource<ClickhouseContainer>(Shared = SharedType.PerTestSession)]
    public required ClickhouseContainer ClickHouse { get; init; }

    [ClassDataSource<PostgresContainer>(Shared = SharedType.PerTestSession)]
    public required PostgresContainer Postgres { get; init; }

    [ClassDataSource<RabbitMqContainer>(Shared = SharedType.PerTestSession)]
    public required RabbitMqContainer RabbitMq { get; init; }

    public async Task InitializeAsync()
    {
        LoadAssemblies();

        _containers = new List<IRapidataContainer>
        {
            Minio,
            MongoDb,
            Mailhog,
            Redis,
            ClickHouse,
            Postgres,
            RabbitMq,
        };
}

public sealed class CampaignApplicationTestHost : ITestHost
{
    [ClassDataSource<MinioContainer>(Shared = SharedType.PerTestSession)]
    public required MinioContainer Minio { get; init; }

    public async Task InitializeAsync()
    {
        LoadAssemblies();

        _containers = new List<IRapidataContainer>
        {
            Minio,
        };
    }
}

This sometimes causes concurrency issues with the following exception:

Failed to inject properties for type 'CreateUnsupportedOrderTests': Failed to initialize data source of type 'ApplicationTestHost': Failed to inject properties for type 'ApplicationTestHost': Failed to initialize data source of type 'MinioContainer': Failed to inject properties for type 'MinioContainer': Operations that change non-concurrent collections must have exclusive access. A concurrent update was performed on this collection and corrupted its state. The collection's state is no longer correct.

Im happy to provide additional info if required
