Hi Katherine2020,
1)Can I check for SDK Silverlight and Silverlight development tools installers, will all these be removed as well?
Yes, you can download it here:Get Microsoft Silverlight .
2) If we retain the existing old installers, can we still use these installers to install on a new windows server/machine?
Not sure if it would work. But we recommend to download and install the latest version.
3) Apart from security patches that will be discontinued and installers will no longer be made available on microsoft sites, are we still able to continue with development work using Silverlight SDK and toolkit for .xap files compilation?
If the SDK and toolkit can be used, it can also work for .xap files compilation.
4) Will silverlight applications go down completely? If there is a browser update to IE 12 for example, will Silverlight becomes incompatible?
No, it won't. Yes, Silverlight will become incompatible with IE12.
By the way, if you have other questions, please refer here:
