Configure persistence for Elsa Core in the appsettings.json

A simple way to enable a feature without persistence:

"Elsa": {
  "Features": {
    "Console": true
    ...

In order to specify persistence for a feature it's required to set enabled status, framework (has to be an empty space for MongoDb) and connection string identifier:

EF Sqlite

"Elsa": {
  "Features": {
    "DefaultPersistence": {
      "Enabled": true,
      "Framework": "EntityFrameworkCore",
      "ConnectionStringIdentifier": "Sqlite"
    },
    ...

EF MySQL

"Elsa": {
  "Features": {
    "DefaultPersistence": {
      "Enabled": true,
      "Framework": "EntityFrameworkCore",
      "ConnectionStringIdentifier": "MySql"
    },
    ...

EF SQL Server

"Elsa": {
  "Features": {
    "DefaultPersistence": {
      "Enabled": true,
      "Framework": "EntityFrameworkCore",
      "ConnectionStringIdentifier": "SqlServer"
    },
    ...  

EF Postgre

"Elsa": {
  "Features": {
    "DefaultPersistence": {
      "Enabled": "true",
      "Framework": "EntityFrameworkCore",
      "ConnectionStringIdentifier": "PostgreSql"
    },
    ...

MongoDB

"Elsa": {
  "Features": {
    "DefaultPersistence": {
      "Enabled": true,
      "Framework": "",
      "ConnectionStringIdentifier": "MongoDb"
    },
    ...

YesSql Sqlite

"Elsa": {
  "Features": {
    "DefaultPersistence": {
      "Enabled": true,
      "Framework": "YesSql",
      "ConnectionStringIdentifier": "Sqlite"
    },
    ...

      "Enabled": true,
      "Framework": "YesSql",
      "ConnectionStringIdentifier": "MySql"
    },
    ...

YesSql SQL Server

    "DefaultPersistence": {
      "Enabled": true,
      "Framework": "YesSql",
      "ConnectionStringIdentifier": "SqlServer"
    },
    ...

YesSql Postgre

"Elsa": {
  "Features": {

      "Enabled": true,
      "Framework": "YesSql",
      "ConnectionStringIdentifier": "PostgreSql"
    },
    ...

Workflow Settings is an optional feature and is controlled by IWorkflowSettingsProvider that currently has the database and configuration providers.

The database provider uses one of available database persistence while the configuration one uses Environment Variables using IConfiguration

The Environment Variable for the configuration provider can be set in the format as follows:

Name: ":disabled" Value:

Configure connection strings for each persistence

  "ConnectionStrings": {
    ...
    "MySql": "Server=LAPTOP-B76STK67;Database=Elsa;Uid=myUsername;Pwd=myPassword;",
    "SqlServer": "Server=LAPTOP-B76STK67;Database=Elsa;Integrated Security=true;MultipleActiveResultSets=True;Max Pool Size=500;Connection Timeout=3600",
    "Sqlite": "Data Source=elsa.sqlite.db;Cache=Shared;",
    "MongoDb": "mongodb://localhost:27017/Elsa",
    "PostgreSql": "Server=127.0.0.1;Port=5433;Database=elsa;User Id=postgres;Password=Password12!;"
