Silverlight 5.0 debugging issue in Windows 10

I recently upgraded my OS to Windows 10 . I have a very simple Silverlight 5 application that gives me a Unable to start Debugging. The Silverlight Developer Runtime Not Installed. Please Installed a matching version error Unable to start Debugging. The Silverlight Developer Runtime Not Installed. Please Installed a matching version Unable to start Debugging. The Silverlight Developer Runtime Not Installed. Please Installed a matching version Unable to start Debugging. The Silverlight Developer Runtime Not Installed. Please Installed a matching version in VS 2010 whenever I try to start a project.

I have:

  • The target Silverlight version is installed in Silverlight 5 in the web project.
  • I have installed the Silverlight SDK , Silverlight5_Tools with SP1 installed and Silverlight Runtime , which is 64-bit .

After completing all these steps and going through many online posts, I still cannot solve this problem.

My doubts:

  • Perhaps the Windows 10 update has anything to do with this situation?
  • Windows 10 comes with the new Edge browser, is it because of this browser? How Silverlight Compatibility.

Again, I'm not sure, but these are my doubts. Any suggestions?

Do you have a 64-bit OS? If so, uninstall Silverlight (developer!) And make sure you install silverlight.exe (developer!), And not the 64-bit version. It worked for me. NTN

Go to the properties of the web folder launch project. Click "Web" on the left tab. Unclick Silverlight in debuggers.

Not a complete solution, but at least it allows you to debug other parts.

I had this problem and uninstalling and reinstalling did not work.

The error in debug mode (Fug Debug configuration) was "Cannot start debugging. Silverlight Developer runtime not set"

In the Debug configuration, I would get the above error, but finally I put the solution in release mode and it worked - then returned to debug mode and everything worked without errors.

It seems like a really strange fix, but quite a complete closure and reopening of the solution, everything works now - the same installation procedure as the OP.

Another interesting thing: Debug only works in Chrome. If I target IE or the edge, I still get "Cannot start debugging. Silverlight Developer runtime not set"

I uninstalled Silverlight and then installed Silverlight_Developer.exe. I also switched the default browser in Visual Studio to Internet Explorer (I have Edge, otherwise it won't work ...).

It's nice to see that even more people today use Silverlight, hehehe.
