Hi,

I am getting this error, when trying to build a VWG library with some controls that I have created.

Error    1    The "GenerateResource" task failed unexpectedly.

What should I do to be able to build the project?

I tried adding these things:

    <TrackFileAccess>false</TrackFileAccess>
    <GenerateResourceNeverLockTypeAssemblies>true</GenerateResourceNeverLockTypeAssemblies>

into the first Project's PropertyGroup in the project file, but they haven't helped me.

Thanks,

Alex

Hi Palli,

Yes, it was a resource file with binary data inside value tag.

  <data name="tbDateTime.ErrorProvider" mimetype="application/x-microsoft.net.object.binary.base64">
    <value>

  </data>

What do you mean by wrong attribute decoration for properties?

This resource file belongs to a class, which inherits from the base class, which inherits from UserControl.

This base class has a property of type ErrorProvider.

    public partial class itUserControl : UserControl
    {
        private ErrorProvider _ep = new ErrorProvider();

        public ErrorProvider ErrorProvider
        {
            get { return _ep; }
            set { _ep = value; }
        }

Is there something wrong with having a property like this in a base class and what's the solution?

Thanks,

Alex
