Hi @james0323 thanks for your query and sorry to hear about your problems.
When you get a System.AggregateException, you should always look at the InnerExceptions and InnerException properties. The original error is usually in one of these properties. However, for use to analyse more fully the issue, we need to know which code line you receive the error. Accordingly, the more detail the better.
Might also be an idea to try running on a more recent VS version just to check. Thanks for your patience whilst we try to resolve your issue.
