PrimusSaaS.MultiTenancy.EFCore 1.0.0

PrimusSaaS.MultiTenancy.EFCore

Release status: stable integration package for PrimusSaaS.MultiTenancy.

EF Core integration package for Primus multi-tenancy.

Validation

• Current workspace validation: covered by the PrimusSaaS.MultiTenancy.Tests suite, which passed 240/240 on net8.0, net9.0, and net10.0, plus smoke tests 5/5
• Scope boundary: EF Core adapters and interceptors only; application tenant lifecycle logic stays outside the adapter

What it provides

• TenantSaveChangesInterceptor for write enforcement:
  • auto-stamps TenantId on new tenant-owned rows
  • blocks cross-tenant update/delete when not bypassing
• AddPrimusMultiTenancy(modelBuilder, filterProvider) for read isolation
• ITenantStore and ITenantMembershipStore EF Core implementations
• ITenantDataRetentionService EF Core implementation for tenant offboarding

Read isolation guard

If your model contains any ITenantOwnedEntity types, a TenantQueryFilterProvider is required. Calling AddPrimusMultiTenancy() without a provider now throws to prevent accidental unscoped reads.

If a context is intentionally write-only for tenant-owned entities, opt out explicitly:

modelBuilder.AddPrimusMultiTenancy(allowUnscopedReads: true);
