Hello,

When I try to compile a project I get this error message

Assembly (WindowsApplication3) is not licensed to use dotConnect for MySQL.
Please correct license information.

and then in the license information, I have that
Unknown project type. Embed licensing information if needed according to dotConnect for MySQL documentation

I have installed the Trial pro version and it's remaning 29 Days

What can I do please?

As I understood, WindowsApplication3 uses the Devart.* assemblies via your class library. Please add the *.exe name (WindowsApplication3.exe) to the licenses.config file as it is described in our documentation (the Class Libraries Support section).

Please tell us the type (ClassLibrary, WinForms, etc) of your project which is not recognized by the Tools > MySQL > License Information menu of Visual Studio.

Hello,

I do that, but I get the same error.
I use the folowing classes:
- Devart.Data.MySql.MySqlConnection
- Devart.Data.MySql.MySqlCommand
- Devart.Data.MySql.MySqldatatable
- system.windows.forms.datagridview (with the Mysqldatatable as datasource)

I add the file "licenses.config" in the "properties" folder of my project (in the same folder as the "licenses.licx")

the file licenses.licx was already created and contain :

Devart.Data.MySql.MySqlConnection, Devart.Data.MySql, Version=6.10.135.0, Culture=neutral, PublicKeyToken=09af7300eec23701

1. Could you please recreate the problem with a simple solution and send it to us (contact form)?

2.1. Have you added licenses.config to your class library project (not to WinForms)?
2.2. Try removing these files (licenses.licx and licenses.config) to the root folder of the project and rebuilding the project (please clear the bin and obj folders of the project before rebuilding).
2.3. Describe your solution (the types of your projects and the chain of calls).

Make sure that references to the Devart.* assemblies in this project are for the 6.10.135 version of dotConnect for Oracle (Devart.Data.dll v 5.0.236, Devart.Data.Oracle.dll v 6.10.135).

Hello,

Sorry for the delay, I can not do more simple, I use 4 composant:

Devart.Data.MySql.MySqlConnection
Devart.Data.MySql.MySqlCommand
Devart.Data.MySql.MySqlDataTable
System.Windows.Forms.DataGridView (with the Devart.Data.MySql.MySqlDataTable as Datasource)

When I'm in the Designer and I open the connection, I see all Data in my grid, but when I compil, the grid is empty and I get the license error.

Hello again, this error coming on the pointer
(self.table as System.ComponentModel.ISupportInitialize).EndInit();

We have answered you by e-mail (it is necessary to put licenses.licx to the root folder of your project).
