Usage

Use the IServiceCollection extension methods when building your service provider

• .UseAzureSynchronization
• .UseAzureServiceBusEventHub
• .UseCosmosDbPersistence
• .UseAzureTableStoragePersistence

services.AddWorkflow(options => 
{
	options.UseAzureSynchronization("azure storage connection string");
	options.UseAzureServiceBusEventHub("service bus connection string", "topic name", "subscription name");
	options.UseCosmosDbPersistence("connection string");
});

Azure Table Storage Persistence

For cost-effective workflow persistence using Azure Table Storage:

services.AddWorkflow(options => 
{
	options.UseAzureTableStoragePersistence("azure storage connection string");
});

You can also specify a custom table name prefix:

services.AddWorkflow(options => 
{
	options.UseAzureTableStoragePersistence("azure storage connection string", "MyWorkflows");
});

Or use with managed identity:

services.AddWorkflow(options => 
{
	var tableServiceUri = new Uri("https://mystorageaccount.table.core.windows.net");
	var credential = new DefaultAzureCredential();
	options.UseAzureTableStoragePersistence(tableServiceUri, credential);
});
