Question:
I’m using Visual Web Developer Express 2010, Windows XP, and using ASP.NET MVC4 RC in a project. I have NuGet v2.0.30619.9119 installed.
I’m now trying to install the MvcScaffolding package via NuGet Package Manager Console. I get the following errors:

Because the init scripts aren’t being executed after the install, the MvcScaffolding package is not installed correctly and the scaffold command is not recognised.
I don’t know what to do about these code signing issues. Here are the current security settings:
|
1 2 3 4 5 6 7 8 9 |
PM> Get-ExecutionPolicy -List Scope ExecutionPolicy ----- --------------- MachinePolicy Undefined UserPolicy Undefined Process RemoteSigned CurrentUser Undefined LocalMachine Unrestricted |
Can I change the Process scope to be Unrestricted? If so, how? Running Set-ExecutionPolicy in the NuGet console does not work:
|
1 2 3 4 5 6 7 8 9 10 11 12 |
PM> Set-ExecutionPolicy Unrestricted Execution Policy Change The execution policy helps protect you from scripts that you do not trust. Changing the execution policy might expose you to the security risks described in the about_Execution_Policies help topic. Do you want to change the execution policy? [Y] Yes [N] No [S] Suspend [?] Help (default is "Y"):Y Set-ExecutionPolicy : Windows PowerShell updated your execution policy successfully, but the setting is overridden by a policy defined at a more specific scope. Due to the override, your shell will retain its current effective execution policy of "RemoteSigned". Type "Get-ExecutionPolicy -List" to view your execution policy settings. For more information, please see "Get-Help Set-ExecutionPol icy." At line:1 char:20 + Set-ExecutionPolicy <<<< Unrestricted + CategoryInfo : PermissionDenied: (:) [Set-ExecutionPolicy], SecurityException + FullyQualifiedErrorId : ExecutionPolicyOverride,Microsoft.PowerShell.Commands.SetExecutionPolicyCommand |
I’ve also tried doing all of this as an Administrator and that didn’t help either.
Any advice or ideas would be much appreciated.
UPDATE
I can set the process execution policy in NuGet like this:
|
1 2 |
Set-ExecutionPolicy Unrestricted -Scope Process |
But when I restart Visual Web Developer, the setting is forgotten and I still get an error as it keeps trying to execute the init.psl files
How can I change the execution policy permanently?
Answer:
OK, I have MvcScaffolding installed correctly now.
I had to first bypass all security in NuGet:
|
1 2 |
Set-ExecutionPolicy Bypass -Scope Process |
But when I restart Visual Web Developer I still get those same PowerShell errors todo with the NuGet running init.pls on startup.
I’ve worked out that it’s because I was storing my project on a network drive. Apparently PowerShell won’t execute scripts from the network drive by default.
I tried using CasPol to change the security settings, but couldn’t get it to work. I gave up when I saw other people couldn’t get VS to work with mapped drives as well:
CAS not working for VS2010 mapped drive
Anyway, I just have my project local now, and MvcScaffolding is installed and working.
