Testing WinForms user control in C#.net

To test our brand new user control, we need to create another project. Then Right-click the solution inside the Solution Explorer and then choose New > Project.

In the Add New Project Window, choose Windows Forms Application and name it EditableLabelDemo. Next, We need to import our control to the Toolbox so we can easily drag it to the form. Once you are presented with a blank windows forms, go to the Toolbox and right-click (You can right-click on the Generals tab to add our control there). Select the option "Choose Items...".

Choose Toolbox Items window, click the Browse button. and We need to browse for the .dll file containing our user control. Browse for the directory where your project was saved. 

Go inside the folder of our Windows Control Library project (named EditorLabel) and inside it, enter the bin folder. The DLL file could either be in the Debug or Release folder. Once you found the EditorLabel.dll, select it and click Open. EditorLabel will now show up in the list of selectable controls inside the Choose Toolbox Item Window. Be sure it's checked and then click OK.
