Good afternoon,
I'm a rookie working with ABP framework, i'm having some difficulties. I have two microservices created in two different solutions, and i want to use the enpoints of one microservice into the other integrating the two. I was thinking generating a nugget package to install in the other service. But your tutorial for the deveopment of the microservices in the ABP framework are created in the same solution. What methodology do you recommend for this integration?
Best regards, Renata Mendes

Hello,
I would suggest checking microservice startup template docs to understand the components of the microservice template.
If you are only interested in communication between microservices, there are two ways to achieve this; synchronous communication and asynchronous communication.

Good afternoon,
I decided to test the microservice startup template indicated for microservices development. I Created with ui blazor server and abp in version 5.0.0. I executed the solution with Tye, but when run the AuthServer application it's not working. AuthServer's log file:

This is a different and duplicate question. You can check the answer for this problem in issue#2512.
