Silverlight 4 Support in Visual Studio 2013

Question

I just installed Visual Studio 2013 and tried to open a project which contained Silverlight 4 projects. In the migration however, the Silverlight target version was changed to 5 and is not not editable in the project settings. There are too many issues with upgrading the project to Silverlight 5 and we're working on converting the Silverlight projects to MVC web apps.

Has anyone had success or have a solution for working with Silverlight 4 projects in Visual Studio 2013 without changing the Silverlight version to 5?

Answer 1

Silverlight 4 is not supported. The list of supported frameworks and targeting packs for Visual Studio 2013 can be found here.

Silverlight

+---------------------+--------------------------------+
| Target Platform     | Targeting pack download        |
+---------------------+--------------------------------+
| Silverlight 5       | Included in Visual Studio 2013 |
|                     | Runtime installer:             |
|                     | Silverlight 5 Runtime          | 
+---------------------+--------------------------------+

For Silverlight 4 and below you'll need to use the older version of Visual Studio or upgrade your project. Officially Silverlight 4 is also no longer supported on older versions of visual Studio though, the primary reason for this is that Silverlight 4 has reached the end of its support lifecycle.

Official overview can be found here.
