Due to a bug with registering AutoMapper profiles, only the first mapping profile would get registered.
Also merged AutoMapper utilities into Elsa.Core.
This solves an issue where the Dashboard site would not be able to run in IIS, due to an IIS filter that expects a IISServer instance, while it was being decorated with a custom type.
Fortunately, as of .NET Core 3, background hosted services now execute before the server starts, which makes them perfect for async initialization.
* Fixed Yaml serialisation/deserialisation
Copied json serializer settings from JsonTokenFormatter, apart from CamelCasePropertyNamesContractResolver, as the yaml already had the correct case, and this would cause activity state (which has PascalCasing) to be camelCased too
* Updated YamlDotNet.Standard to YamlDotNet
Switched package as YamlDotNet.Standard has been unlisted on Nuget
* Added MySqlContext
* Added MySqlContextFactory
* Added Pomelo.EntityFrameworkCore.MySql nuget package
* Added initial MySqlContext migrations
* Added support for creating derived ElsaContexts:
- Added new protected constructor based on following post
- https://github.com/dotnet/efcore/issues/7533
* Added Sample 24 - MySql provider with migration execution
* Updated other samples that needed to define the derived ElsaContext
* Added summary to ElsaContext constructor
* Updated persistence/Elsa.Persistence.EntityFrameworkCore MD file with MySql example
Added extensible support for specialized primitive handling such as
DateTime and NodaTime primitives.
This fixes the issue where a Variable is serialized using a primitive's
string representation and losing the target type, which is needed for
reconstructing the type upon deserialization.
* Explicitly specify identity for Id columns
This fixes an issue where EF Core 2.2 does not set Identity = Yes when
defining the Id columns.
* Fix DateTime serialization issue
This change fixes an issue by taking over the serialization of a DateTime value.
The problem with serializing a DateTime value as-is is that upon deserialization, the JToken type would be set as String instead of Date.
This is because NodaTime disables automatic date time handling for Instant types.
However that causes an issue when trying to serialize and deserialize DateTime values.
This change explicitly tests for DateTime values and handles it appropriately.
A future improvement might be to make this TypeNameHandlingConverter class extensible by implementing a provider-based model,
enabling developers to take control over how certain types are serialized.
