The following error occurred in debugging Silverlight today:

This means "Unable to start debugging because the Silverlight Developer runtime is not installed, please install a matching version". But press CTRL + F5 can debug run, not Ah, a few days ago also good, today how can not do?

Suddenly, a few days ago Silverlight upgrade, so uninstall the Silverlight SDK reload, or there is this error. Here are the solutions:

Uninstalling Microsoft Silverlight

Then reload the Silverlight4_tools.exe, or unzip the Silverlight4_tools.exe, install the Silverlight_developer.exe can be.

Summarize:

Because Silverlight is upgraded, the runtime is upgraded, the development environment and the running environment version are inconsistent, so there are no Silverlight Developer runtime errors found during debugging, so why reload silverlight4_ Tools still can't solve the mistakes? Because of the reload, it detects if a new version exists and is ignored if any. So, we can not solve the problem of unloading load, usually we think that Microsoft Silverlight is for the client, but it contains the Runtime, so it must be uninstalled in order to reinstall the Silverlight Developer Runtime, Resolves an issue with Silverlight run-time errors.

Finally, to remind you that the upgrade is risky, operation should be cautious!
