Hello again,
a colleague of mine updated his ABP Studio, Suite and CLI and tested it on his machine aswell. He didn't have the problem with the creation of the solution. The problem with ABP Suite does occur on his machine too though. Once he creates an entity and presses "save and generate", the microservice project can't be built because of this line in the ProcessServiceDbContext.cs:
using MeinTestDemoWerk.ProcessService.Processes;
Was someone able to check this and if so when might a new version release with the fix?
