Aspnetboilerplate: Single tenant – single database -- Multiple DbContext Issue

Created on 11 May 2016 · 3Comments · Source: aspnetboilerplate/aspnetboilerplate

First, Thank you for your awesome work.
I've upgrade my solution to ABP v0.9 and I started to face an issue with the DbContext injection

Background
My Solution is Single tenant – single database -- Multiple DbContext. I've multiple modules and every module has its own DbContext and all of the modules inheriting the base module DbContext
I've also a Base Repository and all the module Base Repositories inherits it and inject IDbContextProvider to it.

I'm using AutoRepositoryTypesAttribute to Register the Repositories.

Problem

After Upgrading to v 0.9 I started to get the below issue. If I enable MultiTenancy the problem disappear. If MultiTenancyis disabled the problem exist.

When I inject ISalesRepository (Entity one of the Sales Modules Entities) It inject the base Module DbContext while he should inject the SaleDbContext.

I've Created a new Project from the Template and I was able to regenerate the issue. I'm attaching here a Project that shows the issue.
If you Call the Sales Application Service It will fail unless you Enable the MultiTenancy.
