Unable to compile the treetest with version 1.2

The following error occurs when I compile the attached source code with Web Core VCS 1.2

Treetest.zip (107.8 KB)

This appears to be an issue with the trial version. With the trial version we can reproduce this. With the full registered version, this works.
This must be an issue with compiled trial version files. We will investigate this.

I downloaded the vsix file today! Haven’t used a trial version.

You need to activate it with your credentials.

That does the trick, though it's a bit confusing. Previously it was possibly to compile and clear message appeared explaining to enter credentials

On what operating system are you working?

Win10 64 bits

We will investigate and try to make it work better out of the box.
