Error when setting data property

I'm getting the following error
2020-02-15 13:24:09.727] [error] EPERM: operation not permitted, rename 'D:\Projects\Web\blazor\Radzen\PDA\web\meta\pages\test.json.tmp' -> 'D:\Projects\Web\blazor\Radzen\PDA\web\meta\pages\test.json'

Happens when changing the data property on a bound item, for example.dropped a datalist onto a new page and set the data property.

Using latest version.


Something prevents Radzen from saving the page but we are not sure what. Does it happen for all pages? Does restarting Radzen help?

I've had it on a few pages occasionally. I'll try to pin it down further.

I think it's related to the code recompiling in the background - ie the program is running whilst changes are made in designer.

I'm having the same issue, but as soon as I dismiss the error dialog, the TMP file disappears and the JSON file is present. The contents of the JSON file match exactly the contents of the TMP file (which I checked before I dismissed the error dialog), so it doesn't actually look like an error is happening except for the actual error message.

FYI, all my files are local (on my C drive).
