A microservices powered Questionnaire sample - Based on SOA Principles and messaging using NServiceBus.

This sample aims to demonstrate how to compose, and de-compose, data owned by different services in order to display data to end users and allow users to manipulate data.

The application allows to create a very basic questionnaire, where each question can have multiple answers, one of which can be marked as the correct answer.

Currently supported features:

• Display list of questions
• Create a new question (via composite PUT support)
• Recovery from services failure at write time

Partially supported features:

• Edit an existing question:
  • UI is complete
  • composite POST support is missing

Not (yet) supported features:

• Delete questions
• Multiple questionnaires
• Reorder questions
• Reorder answers
• Ability to execute questionnaire and store results

• Right-click on the downloaded copy
• Choose Property
• On the Property page tick the unblock checkbox
• Press OK

In order to run the sample the following machine configuration is required:

• Visual Studio 2017 with .NET Core 2 support (Community Edition is supported), available for download at https://www.visualstudio.com/downloads/

• A SQL Server edition or the LocalDB instance installed by Visual Studio, in case of a clean machine with LocalDBonly please install. A stand along LocalDB installer is available at https://www.microsoft.com/en-us/download/details.aspx?id=29062

Open an elevated command prompt, navigate to your copy of this repo, and run:

powershell -NoProfile -ExecutionPolicy unrestricted -File scripts\Setup-LocalDBInstance.ps1

When you no longer need to run the exercises, you may optionally run Teardown-LocalDBInstance.ps1.

Now connect to your LocalDB instance and run:

• scripts\Setup-Databases.sql.
• scripts\Create-Tables.sql

You can do this using either SQL Server Management Studio (if you already have it installed) or Visual Studio. If using Visual Studio:

• Open scripts\Setup-Databases.sql
• From the Visual Studio menus, select SQL -> Execute
• Choose this instance: Local -> CompositeQuestionnaire
• Click "Connect"
• After the query has run, ensure that you see "Command(s) completed successfully."
• Do the same for scripts\Create-Tables.sql

This sample has no NServiceBus related pre-requisites as it's configured to use the new Learning Transport and Learning Persistence explicitly designed for short term learning and experimentation purposes.

They should also not be used for longer-term development, i.e. the same transport and persistence used in production should be used in development and debug scenarios. Select a production transport and persistence before developing features.

NOTE:

• Do not use the learning transport or learning persistence to perform any kind of performance analysis.
• All solutions are configured to use the SwitchStartupProject Visual Studio Extension to manage startup projects. The extension is not a requirement, it's handy.
• A LINQPad script is available to automatically configure startup projects for all solutions in the demo
