I've been dealing with this problem for awhile now and haven't managed to progress any further for the past few hours so I thought I'll ask here. When I'm opening the designer window in winforms I get to this error screen. Which after about 5 to 10 seconds freezes my Visual Studio and then crashes and reopens automatically. When this happens I can go to my event viewer and find the following two error messages

winforms c#

The error message explains that your form during it's instantiation process (in constructor or somewhere called from there) is trying to access a ActionLogService.IActionLogService which is not available. If you click on Show Call Stack link you will see where is that code line.

I would open the code file without designer support, go to that line and change it like this:

if (!this.DesignMode) 
{
   // here comes the original ActionLogService lines
}
else
{
   // here optionally could be something mocking the ActionLogService during design time
}

E.g. I have a dialog with a dynamic list of actually available choices calculated and returned by a webservice call. During design time I do not want the webservice to be available but wanted to see some dummy values instead in the list. Here it is:

List<string> availableChoices;
if (!this.DesignMode)
{
   availableChoices = GetAvailableChoicesFromWebserviceCall();
}
else
{
   availableChoices = new List<string>() { "dummyDesignTimeOption1", "dummyDesignTimeOption2" };
}
