Accountant Web Application (real name is hidden)

The task was to migrate the existing single-tenant WPF application (VB.NET) to the multi-tenant WEB application based on ASP.NET Core. Also we wanted to leave the existing DB schema for the compatibility reasons. Also one of the main requirement was to reuse the existing CrystalReports templates. Client has provided the ready CSS Theme and I have built the the ASP.NET Core 2.1 web application using EntityFramework Core and ASP.NET Identity. Challenges passed: 1. Integrate the multi-tenancy to the existing DB 2. Migrate the accountant calculation logic from VB.NET (poor quality code) 3. Migrate the CrystalReports and run them under the ASP.NET Core (which is not officialy supported yet and has no documented solution) 4. Migrate the main CRUD operations from stored procedures to EF 5. Integrating multi-tenant support to the EF DbContext I was working with experienced client's developer who taken care about most of the CSS tasks and CrystalReports tasks. As the result we have delivered a MVP in 3 months from start and moved the project to the Alpha testing stage.
