ApiException`1: path/conflict/folder/ error on fresh installation of SimpleTest

Question

Was having some issues with Dropbox, so decided to go back to basics, and found even SimpleTest wasn't working, so I deleted and recloned, changed only the apikey in SimpleTest, and this time I managed to get the app authoristion screen to come up (wasn't getting that far before), so all appeared to be working now... until this -

System.AggregateException
HResult=0x80131500
Message=One or more errors occurred.
Source=mscorlib
StackTrace:

at SimpleTest.Program.Main(String[] args) in D: \Users\Donald\Source\Repos\dropbox-sdk-dotnet\dropbox-sdk-dotnet\Examples\SimpleTest\Program.cs:line 47

Inner Exception 1:
ApiException`1: path/conflict/folder/.

As noted, this is a fresh installation of dropbox-sdk-dotnet (I deleted the whole folder before recloning), so there shouldn't be any problems with existing folders. What do I need to do to fix this?

This error message indicates that the operation (e.g., uploading a file or creating a folder) couldn't be completed because there is already a folder at the specified path.

The .NET SDK 'SimpleTest' examples uses a folder named "DotNetApi" in the root of the connected Dropbox account to store the test files, so this error would be referring to that folder (or something under that folder), not the "dropbox-sdk-dotnet" SDK folder itself. (If the app key is for an app with the "app folder" permission, this would be created inside the special "app folder", by default at /Apps/<app folder name>, automatically made for the app.)

To avoid this, you can delete the entire "DotNetApi" folder in the connected Dropbox account to start over.
