v0.22.1393

• New: To customize how a specific read model is initially created, implement
  a specific IReadModelFactory<> that can bootstrap that read model
• New: How EventFlow handles MSSQL read models has been refactored to allow
  significantly more freedom to developers. MSSQL read models are no longer
  required to implement IMssqlReadModel, only the empty IReadModel
  interface. Effectively, this means that no specific columns are required,
  meaning that the following columns are no longer enforced on MSSQL read
  models. Use the new required MsSqlReadModelIdentityColumn attribute to mark
  the identity column and the optional (but recommended)
  MsSqlReadModelVersionColumn to mark the version column.
  • string AggregateId
  • DateTimeOffset CreateTime
  • DateTimeOffset UpdatedTime
  • int LastAggregateSequenceNumber
• Obsolete: IMssqlReadModel and MssqlReadModel. Developers should instead
  use the MsSqlReadModelIdentityColumn and MsSqlReadModelVersionColumn
  attributes to mark the identity and version columns (read above).
  EventFlow will continue to support IMssqlReadModel, but it will be
  removed at some point in the future
• Fixed: Added missing UseElasticsearchReadModel<TReadModel, TReadModelLocator>()
