Visual Studio设计器不会显示我的用户控件，但可以正常运行应用程序

Question

for some reason my user controls display the error 'Cannot locate resource 'resources/backicon.png'. I am confused as to why this is happening as the program runs fine it just cannot create an instance of the controls in the designer and is displaying a blue warning here: ''. The path in the error is 'resources/backicon.png' however in the actual user control the path is specified as '/Resources/BackIcon.png'. Also the build action for the images is set to resource.

(I'm running Visual studio 2013 Express for Windows Desktop)

Answer 1

Right Click->Clean
Once its cleaned
Now RightClick-> Rebuild
You will see the blue warning gone.
Its because your user control must be added later on which resulted in designer not having any reference as its using previous build as base

Answer 2

Explicitly specify the assembly name in the path although it belongs to the same assembly.

pack://application:,,,/MyAssemblyName;component/MyResourcesFolder/MyImage.png

Make sure You set the build action of the image to the type 'Resource'.
