Configure Elsa 3 migration to SQL Server

[leostone68]

I need to configure Elsa to use SQL Server and perform the migration. Then tell me what packages to install for Elsa 3.1.3?

To configure Elsa to use SQL Server for persistence in Elsa 3.1.3, you will need to install the appropriate NuGet packages and configure your application accordingly. Here are the steps you should follow:

1. Install the necessary Elsa 3.x NuGet packages for Entity Framework Core and SQL Server support. You can use the following commands:

   dotnet add package Elsa
   dotnet add package Elsa.EntityFrameworkCore.SqlServer
   

2. In your Program.cs or startup configuration file, set up Elsa with Entity Framework Core using the SQL Server provider. Here's an example of how you might configure it:

   builder.Services.AddElsa(elsa =>
   {
       elsa.UseEntityFrameworkPersistence(ef => ef.UseSqlServer("YourConnectionString"));
   });

   Replace "YourConnectionString" with your actual SQL Server connection string.

3. Perform the migration to create the necessary tables in your SQL Server database. You can use the following command:

   dotnet ef migrations add InitialCreate -o Data/Migrations
   dotnet ef database update
   

   Make sure that the Entity Framework Core tools are installed for these commands to work. If not, you can install them using:

   dotnet tool install --global dotnet-ef
   

4. Ensure that your application is correctly configured to use the Elsa services and middleware as needed.

By following these steps and using the provided commands, you should be able to set up Elsa to use SQL Server for persistence in your application with Elsa 3.1.3.

Resolved with:
elsa.UseWorkflowManagement(management => management.UseEntityFrameworkCore(ef => ef.UseSqlServer(sqlServerConnectionString)));

In 3.5.0 if you configure Identify, Runtime, and Management to use EF Core, there appear to be different DbContexts for each and you have to specify these when running the dotnet EF commands in Visual Studio CLI or Powershell. To get migrations working in a custom project using Elsa I therefore had to run these commands:

dotnet ef migrations add InitialCreate -o Data/Migrations/Management --context Elsa.EntityFrameworkCore.Modules.Management.ManagementElsaDbContext
dotnet ef migrations add InitialCreate -o Data/Migrations/Runtime --context Elsa.EntityFrameworkCore.Modules.Runtime.RuntimeElsaDbContext
dotnet ef migrations add InitialCreate -o Data/Migrations/Identity --context Elsa.EntityFrameworkCore.Modules.Identity.IdentityElsaDbContext
dotnet ef database update --context Elsa.EntityFrameworkCore.Modules.Management.ManagementElsaDbContext
dotnet ef database update --context Elsa.EntityFrameworkCore.Modules.Runtime.RuntimeElsaDbContext
dotnet ef database update --context Elsa.EntityFrameworkCore.Modules.Identity.IdentityElsaDbContext

Luckily there is only one shared Migration Table and you probably only have to run these one time.
