Updated @ Apr'19

Simple ASP.NET Core Middleware (1-2h)

Create a middleware in a ASP.NET Core that implements the following functionality:

• Replace rl with rocketloop in all values of JSON requests
• The middleware should only trigger for a configurable list (regular expressions) of endpoints
• Write tests using XUnit for requirements mentioned above

Architecture and Design (30m - 1h)

There are numerous project design patterns that can be used in ASP.NET Core applications. Two very common patterns are either organizing files with similar functions in common folders and namespaces (e.g. Data, Services, Filters, etc.) and organizing files with a similar scope in one folder and namesspace per feature (e.g. Register/Models, Register/Filter, Register/Controllers, etc.) (feature folders).

Please discuss the arguments for and against both patterns in a few bullet points and explain which pattern you'd prefer for a simple CRUD web API and why.

API Design (1h)

Describe (in text or as swagger) the REST API design for the following application:

A customer wants to implement a simple TODO List application: Todos are organized as lists of simple todos (text + status). Multiple lists are organized as one board (both only having a title). A user is able to create, update and delete boards, lists and todos they have access to. By default a user has access to the boards they have created. A user is able to invite other users to a board he created. For this assignment you can ignore other user related logic (registration, password reset, etc).
