I am trying to save a WriteableBitmap to local in Silverlight using SaveFileDialog. A question similar to mine is asked Here.
And the answers show several opensource encoders and workarounds. They work fine.
But why silverlight doesn't support encoders for JPEG/PNG/BMP itself while .NET framework and WPF support all of them? Why should we apply for third party classes?
I thought for a whole night, but failed to figure out why. Since I am not allowed to use third party classes, I have to write an encoder myself.:(
If you mean you aren't allowed to purchase third-party components, then use open source. Take a look at FJCore:

If you aren't allowed to use any classes you didn't write, you need to have a serious conversation with management.
