SetTenant<TKey>(SendContext, TKey)Copy Anchor Link

Makes the message carry tenantId, so it is consumed as that tenant (pro.AddMassTransitPropagation()), whichever tenant is current, if any: for publishing on a tenant's behalf from code that runs without one, such as a scheduled task or an administrator's request.

public static void SetTenant<TKey>(this SendContext context, TKey tenantId) where TKey : IEquatable<TKey>, IParsable<TKey>

Type parameters:

• TKey: The tenant identifier type.

Parameters:

• context SendContext: The message's context, in the callback that Publish or Send takes.
• tenantId TKey: The tenant's id. The tenant is looked up when the message is consumed.

Exceptions:

• ArgumentException: tenantId is the key type's default value (Guid.Empty, 0) or an empty string, which Tenantry reserves for "no tenant".

It sets the TenantPropagation.HeaderName header. MassTransit runs the callback after the bus's filters, Tenantry's among them, so the tenant it sets is the one the message carries.

await bus.Publish(new InvoiceDue(invoiceId), context => context.SetTenant(tenantId));
