title: Creating Windows 10 Transparency effects in c# form
body: <p>How do you create the transparency effects that you see in windows 10? Something like this:</p>
  
  <p><a href="https://i.stack.imgur.com/MbPSU.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/MbPSU.png" alt="The blur effect can also be seen on Edge browser"></a></p>
  
  <p>I have no clue how to approach this in c#. Logically thinking I would take a snapshot of the desktop every time the form comes into focus. Then blur it and place it at 0, 0(screen to client coordinates). That doesn't seem very effective. Any help? Again. not an experienced C# programmer, so a detailed explanation would be much appreciated</p>
  
  <p>Edit: I saw some the answers referring me to a page for alpha blending. This is not what I am looking for. I wanted to know how to create the blur that you see in the image, the rest I can figure out at my own pace</p>
