    <p>So I installed the new MVC3 tooling update and attempted to create a new MVC3 web app. The project reports as being successfully created but if I bring up the Package Manager Console, I see the following...</p> <blockquote> <p>The following error occurred while loading the extended type data file: , D:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\Extensions\Microsoft Corporation\NuGet Package Manager\1.2.20325.9034\Scripts\NuGet.Types.ps1xml : File skipped because of the following validation exception: File D:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\Extensions\Microsoft Corporation\NuGet Package Manager\1.2.20325.9034\Scripts\NuGet.Types.ps1xml cannot be loaded.

There were errors in loading the format data file: D:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\Extensions\Microsoft Corporation\NuGet Package Manager\1.2.20325.9034\Scripts\NuGet.Format.ps1xml, , D:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\Extensions\Microsoft Corporation\NuGet Package Manager\1.2.20325.9034\Scripts\NuGet.Format.ps1xml : File skipped because of the following validation exception: File D:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\Extensions\Microsoft Corporation\NuGet Package Manager\1.2.20325.9034\Scripts\NuGet.Format.ps1xml cannot be loaded.

Please see "get-help about_signing" for more details...</p> </blockquote> <p>So it appears that there are two errors occurring here, one while trying to load the extended data file and one while loading a format data file.</p> <p>I have installed powershell 2.0. Anyone have any ideas? Should I care if the project got created successfully (I think)?</p>

    1. COIf you open up a powershell prompt and run Get-ExecutionPolicy, what does it say? Do you see this error if you reset VS and create a new MVC app?

    2. COGet-ExecutionPolicy reports RemoteSigned. Not a PS expert so not sure if that's good or bad. The good news is that apparently simply restarting VS (twice) did the trick. Must have been some odd file handle that wasn't releasing.

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
