I work for Het CAK in the Netherlands and develop backend functionality in .Net.

Currently we are implementing an exchange with member states using EESSI for "Actual cost claims" (S_BUC_19, AW_BUC_05) and "Fixed amounts" (S_BUC_21). The technologies we use are:

• EF Core
• Oracle DB
• ActiveMq classic
• MassTransit (@phatboyg)

Our usage of ActiveMq was my drive to implement an ActiMq Classic host component for the Aspire CommunityToolkit that could be used by ActiveMq. I did this because MassTransit expects a scheme "activemq" in the connectionstring. ActiveMq Artemis is now also available.

I also implemented a hosting component for testing integrations with SMTP using Papercut SMTP.
