Error while trying to open the Signing page in Properties of a Silverlight project

Question

Configuration: VS 2012 Professional, Windows 8

Steps to reproduce:

1. Open VS 2012.

2. Create new Silverlight 5 Business Application.

3. Open Silverlight project properties and click Signing tab => An error occurred trying to load the page. Class not registered. Looking for object with CLSID: {B07DA5DD-055B-4018-88F3-3A433FDB9B25}.

The same problem as described here: http://connect.microsoft.com/VisualStudio/feedback/details/647881/error-while-trying-to-open-signing-page-from-properties-of-a-silverlight-project

Any ideas?

Answer 1

I'm having the very same problem, in 2 different computers (a desktop system and a HP Pavillion notebook), both equipped with Windows 8 and VisualStudio 2012 pro.

No idea...

Answer 3

I have the same issue. Signing was working fine in vs2010, then when upgraded, now I get the same error message and can't open the signing page.

Any new information?

There's a workaround posted here: http://connect.microsoft.com/VisualStudio/feedback/details/760967

You can use signtool.exe to sign your project. In post build event command line add something lke this:
"C:\Program Files (x86)\Windows Kits\8.0\bin\x86\signtool.exe" sign /v /f f:\Certificates\YOURCERTIFICATE.pfx /p YOURPASSWORD /t TIMESTAMPING_URL $(TargetName).xap

Answer 6

Does the recently-posted registry key patch under http://connect.microsoft.com/VisualStudio/feedback/details/760967's workarounds help?

Answer 7

That URL seems to be wrong. Any idea what the right one is and where this key can be found?

Answer 8

If you log into Connect, select product "Visual Studio and .Net Framework" then search for "760967" (type: feedback), do you see an article titled "VS2012 PRO does not showing Silverlight 5 signing project properties"?

Answer 9

I do, however when I click on the link to it, I get a "Page Not Found" :(

Answer 10

Strange. At any rate, here's a revised version of work-around I posted:

Based on Process Monitor output, Visual Studio is looking for in HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\11.0_Config\CLSID\ for a key named {B07DA5DD-055B-4018-88F3-3A433FDB9B25}. For whatever reason, VS 2012 Pro's installer doesn't always create this key. 

It appears that this key can be created manually as follows (adapted from how VS 2010 Pro set up the equivalent key):

=== Patch.reg ===
Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\11.0_Config\CLSID\{B07DA5DD-055B-4018-88F3-3A433FDB9B25}]
"Class"="Microsoft.VisualStudio.Silverlight.SigningPropertyPageComClass"
"Assembly"="Microsoft.VisualStudio.Silverlight, Version=11.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
"ThreadingModel"="Both"
"InprocServer32"="c:\\Windows\\SysWOW64\\mscoree.dll"
@="Microsoft.VisualStudio.Silverlight.SigningPropertyPageComClass"

Answer 11

Thanks for the key. However, it didn't work :(

I now get "Unable to create the designer. File is already opened in an incompatible editor".

Answer 12

Hi BenCHK, it worked for me!

Thanks a bunch!

Ha, I just retried it today and it now works! Probably needed a machine restart? (weird)

Thanks a lot!
