I\'ve created a C# WinForms application using VS2010. I\'m new to creating user controls so I created a new user control (as part of the same project).
When I rebuil
Same problem here. I am guessing it is related to the fact that the VS2010 installed on x64 OS is still a 32bit program in the heart.
An alternative solution one might want to try is simply open TheFormThisUserControlIsSupposedToBeAddedTo.Designer.cs and use code to add the user control. Basically, you are doing the dirty work that the Designer is supposed to do.
It is not as difficult as it sounds, esp. considering that there are probably plenty of sample code in that file already (e.g. the buttons you added using Designer). The only difficult part is figuring out the right coordinates in the form to place the control.
The end result is that you can not see the user control in Desinger, but they are added on debugging/running.
