I am writing a web service application project of type Silverlight. When I run the project I get the following error. "Unable to start debugging. The Silverlight Developer runtime not installed. Please install a matching version" The software is VB.Net 2010 with SP1 installed. OS is windows 10. The Silverlight sdk 3, 5 are already installed. I would be grateful if you can help me out.
Thanks.

What I have tried:

1. Formatting the Laptop and re-installing the VB.Net 2010 again.
2. Tried the following references of silverlight
(a) imports System.data.services.Client
(b) imports System.xml

Solution 1

As the error message is yelling you not only need Silverlight, but the Silverlight Developer runtime also known as Silverlight SDK (Software Development Kit).

Consider using other software libraries because Silverlight is somehow deprecated, so it is a dead end lane.

When I download and Install the kit it says "A newer version is already installed."

Solution 2

I would seriously reconsider targeting Silverlight. The platform is dead. It was Microsoft's attempt at replacing Flash. Even Flash is dying off, thankfully.

Solution 3

Try installing the "Silverlight managed debugging package", as mentioned here:
Resolve “Unable to start Debugging.The SilverLight Developer Runtime Not Installed. Please Install a matching version” – Visual Studio 2010, Silverlight 4 – Alik Levin's[^]

It is same as installing Silverlight_developer.exe(same as above in solution 1 above). It says a newer version already installed.

Also tried installing Silverlight5_Tools.exe. The problem persists.

Which version of Silverlight are you using? If it's v3, you'll probably need the Silverlight 3 SDK update. Apparently, there was a bug that prevented VS2010 from updating the SDK properly, so you need to uninstall the old version first:

Visual Studio 2010 and Silverlight 3 SDK[^]
Microsoft® Silverlight™ 3 SDK[^]

The computer was formatted and vs 2010 with sp1 was reinstalled. Hence Silverlight 3 was reinstalled along with VS 2010 installation.You mean there is this bug in the original ver. of Silverlight 3 that came with VS 2010 ?

Richard Deeming 11-Jul-17 13:12pm

According to the MSDN blog post[^], there was a bug with the version that pre-dated VS2010 (SDK v3.0.40624).

However, it implies that you should still be able to do SL3 development in VS2010 with the old SDK installed.

My installation includes the required build ie 3.0.40818 of s3. I checked it from Add/Remove programs. But the problem continues.
