New version of SSDT Power Tools are available – but with a caveat

A little over a month ago the first version of the SSDT Power Tools were made available bringing with them some much needed functionality – a replacement for Schema View called SQL Server Object Explorer.


Along with the first release of the power tools came a promise that they would be updated on a regular cadence and, true to their word, an updated version (v1.1) is already available.

If you have got v1.0 installed then you should automatically be notified about the update. However, an attempt to apply the update results in this little nasty:


Here’s the full text of that error in case anyone happens to Bingle* for it:

Digital signature mismatch

The signature on the update version of 'SSDT Power Tools' does not match the signature on the installed version. Therefore, extension manager cannot install the update.
If you trust the update, try the installation again after you install the installed version.

Now, according to this KB article this isn’t an issue with the extension, it is actually an issue with the Extension Manager in Visual Studio 2010 Service Pack 1 hence the recommended course of action is to uninstall and then reinstall from the gallery


I did this and it worked just fine.

Of course, the only missing information is what is new in this update and a cursory search hasn’t uncovered anything. I suggest keeping an eye on the SSDT blog to see if any such news transpires.


*Bingle – to search using Google or Bing. I first saw “Bingle” in an email a few weeks ago from Glenn Berry (blog |twitter) and it rather amused me so I’m adopting it for the foreseeable future Smile

"1.1 just contained a small detection logic fix and was uploaded primarily to test things out on our side, which is why we didn't advertise it.  When we're ready to ship an update with real functionality changes, we'll make sure to let everyone know and to tell them about the signature issue."
