I just want to extend Simon D. answer. What he is proposing is the solution that i am using right now. I just wanted to share complete source code. It is from this Trick To Use A ResourceDictionary Only When In Design Mode source.

public class DesignTimeResourceDictionary : ResourceDictionary
{
    /// 

    /// Local field storing info about designtime source.
    /// 
    private string designTimeSource;

    /// 

    /// Gets or sets the design time source.
    /// 
    /// 
    /// The design time source.
    /// 
    public string DesignTimeSource
    {
        get
        {
            return this.designTimeSource;
        }

        set
        {
            this.designTimeSource = value;
            if ((bool)DesignerProperties.IsInDesignModeProperty.GetMetadata(typeof(DependencyObject)).DefaultValue)
            {
                base.Source = new Uri(designTimeSource);
            }
        }
    }

    /// 

    /// Gets or sets the uniform resource identifier (URI) to load resources from.
    /// 
    /// The source location of an external resource dictionary. 
    public new Uri Source
    {
        get
        {
            throw new Exception("Use DesignTimeSource instead Source!");
        }

        set
        {
            throw new Exception("Use DesignTimeSource instead Source!");
        }
    }
}
