Target Invalid : RichTextBox

Just one thing, the program does not write into the existing RichTextBox but creates a new one.
I read it can be related to the declaration of the logger but i do declarate him after the InitilizeComponent.

Actually it's related to initialization of the logging configuration, and it may happen earlier. For example if you create other loggers.

To solve this, call NLog.Windows.Forms.RichTextBoxTarget.ReInitializeAllTextboxes(this) after InitilizeComponent() and before logging anything to this target. This would tell configuration to search for new controls in this form.

The warning is not a harmful one, it just says that Nlog.xsd has no info on RichTextBox, which is really true.

This by itself should not cause any problems to you. What are the problems you are experiencing? Also, you have internal logging set to log internal warnings to nlog-internal.log which is nice. Could you please check if this file contains anything?

I restarted with a blank projet from zero and this time it works. No explanation...
