use an enum type to indicate your ViewModel's State

public enum ViewModeType
{
    Default, 
    Busy
    //etc.
}

then in your ViewModels Base class use a property

public ViewModeType ViewMode
{
    get { return this.viewMode; }
    set
    {
        if (this.viewMode != value)
        {
            this.viewMode = value;
                            //You should notify property changed here
        }
    }
}

and in view trigger the ViewMode and if it is busy show busyindicator:

<Trigger Property="ViewMode" Value="Busy">
    <!-- Show BusyIndicator -->
</Trigger>

This is an update to the code given by  HAdes to parameterize width  height  and ellipse size  This implementation automatically calculates required angles  widths  and heights on the fly  The user

The customized spinner posted by  Menol had a small issue where the spinner would be shifted down and to the right by the size of one dot  I have updated the code so that it compensates for this offset by subtracting by half the dot    Here is the updated code       private void initialSetup                 float horizontalCenter    float  SpinnerWidth   2           float verticalCenter    float  SpinnerHeight   2           float distance    float Math Min SpinnerHeight  SpinnerWidth    2          float dotComp    float  EllipseSize   2            double angleInRadians   44 8          float cosine    float Math Cos angleInRadians           float sine    float Math Sin angleInRadians            EllipseN   newPos left  horizontalCenter - dotComp  top  verticalCenter - distance - dotComp           EllipseNE   newPos left  horizontalCenter    distance   cosine  - dotComp  top  verticalCenter -  distance   sine  - dotComp           EllipseE   newPos left  horizontalCenter   distance - dotComp  top  verticalCenter - dotComp           EllipseSE   newPos left  horizontalCenter    distance   cosine  - dotComp  top  verticalCenter    distance   sine  - dotComp           EllipseS   newPos left  horizontalCenter - dotComp  top  verticalCenter   distance - dotComp           EllipseSW   newPos left  horizontalCenter -  distance   cosine  - dotComp  top  verticalCenter    distance   sine  - dotComp           EllipseW   newPos left  horizontalCenter - distance - dotComp  top  verticalCenter - dotComp           EllipseNW   newPos left  horizontalCenter -  distance   cosine  - dotComp  top  verticalCenter -  distance   sine  - dotComp

The approach is to use geometry with animations applied  Add the required geometry to the Path and animate its RotateTransform from 0-360    My spinner support two types of spinners   Circles      Rings       And the central logic looks like  if spinner SpinnerType    SpinnerType Ring     double innerRad   spinner Radius - spinner ItemRadius   Point center   new Point 0  0    grp Children Add new EllipseGeometry  center  spinner Radius  spinner Radius     grp Children Add new EllipseGeometry center  innerRad  innerRad                     return    var points   GetPointsOnCircle  spinner Diameter  2   double r   spinner ItemRadius  foreach  var point in points     grp Children Add new EllipseGeometry point  r  r     r -  spinner ContinuousSizeReduction     Usage is as simple as follows   lt local SpinnerControl Diameter  quot 60 quot  Fill  quot  FFE8B311 quot   gt  Here is the source code

You can do it without any additional controls and libraries  using only Image control and transform    lt Image     Source   images spinner png      Width  100      Height  100      RenderTransformOrigin  0 5  0 5  Visibility   Binding IsLoading  Converter  StaticResource BooleanToVisibilityConverter    gt       lt Image RenderTransform gt           lt RotateTransform x Name  noFreeze    gt       lt  Image RenderTransform gt       lt Image Triggers gt           lt EventTrigger RoutedEvent  Loaded  gt               lt BeginStoryboard gt                   lt Storyboard gt                       lt DoubleAnimation                         Storyboard TargetProperty   Image RenderTransform   RotateTransform Angle                           To  360  Duration  0 0 1  RepeatBehavior  Forever    gt                   lt  Storyboard gt               lt  BeginStoryboard gt           lt  EventTrigger gt       lt  Image Triggers gt   lt  Image gt    Replace  images spinner png with your image  Change To  360  to To  -360  if you want to rotate it counterclockwise  Duration  0 0 1  equals to 1 second per rotation

This repo on github seems to do the job quite well   https   github com blackspikeltd Xaml-Spinners-WPF  The spinners are all light weight and can easily be placed wherever needed  There is a sample project included in the repo that shows how to use them   No nasty code-behinds with a bunch of logic either  If MVVM support is needed  one can just take these and throw them in a Grid with a Visibility binding
