Thanks for your feedback. We would be happy to troubleshoot the issues you are having, and it would help us if you could provide some more information on which steps were successful and which failed for you.
Are you saying that you were able to install the product, create a new project, import the model from a database, and generate the application code, but the generated code does not compile?
Also, do you mean that you were able to do any of the steps after the installation only after you restart your computer? The plugin installation may not register properly if the visual studio is running during installation, so a visual studio restart is typically needed in such case.
