are there any multitenant cms based on .net

Question

Can you recommend me any multitenant CMS? I am looking for the following features:

1. One different site per tenant
2. Each tenant must have its own independent database
3. Different authentication methods
4. Be able to create custom forms with custom fields, I know a CMS is a content management system, but we want to use a CMS as a starting point for custom applications, where I can add orders, invoices, etc, but I dont want to build that from scratch.

Answer 1

Orchard is a CMS built on top of ASP.NET MVC, and has a multi-tenancy module. This allows for using a different databases per tenant.

It is extensible by developing your own modules.
