 Post Installation:
   - Read the release notes for your version https://github.com/cefsharp/CefSharp/releases (Any known issues will be listed here)
   - Read the `Need to know/limitations` section of the General usage guide (https://github.com/cefsharp/CefSharp/wiki/General-Usage#need-to-knowlimitations)
-  - For `x86` or x64` set your solution target architecture to `x86` or `x64`, just changing the project is currently not enough (See https://msdn.microsoft.com/en-us/library/ms185328.aspx#Anchor_0 for details).

   - `AnyCPU` target is supported though requires additional code/changes see https://github.com/cefsharp/CefSharp/issues/1714 for details.
   - After installing the `Nuget` package we recommend closing Visual Studio completely and then reopening (This ensures your references show up and you have full intellisense).
   - Check your output `\bin` directory to make sure the appropriate references have been copied.
