I am creating a view in Microsoft Visual Studio 2012 Express and I want it to be a strongly-typed partial view, but I am getting the following error:
C:\Program Files(x86)\Microsoft Visual Studio 11.0\Common7\IDE\VWDExpress\Item Templates\CSharp\Web\MVC 4\CodeTemplates\AddView\CSHTML\Empty.tt(-1,1) : error : There was a problem getting an AppDomain to run the transformation from the host. The process cannot continue.
I have not had any trouble creating views that are not partial views, strongly-typed or not.
Is simple... Just restart Visual Studio.

I was using Visual Studio 2013 Professional and had the same issue and none of the following worked for me-
- Restarted VS- didn't helped
- There was no
<NetFx40_LegacySecurityPolicy enabled="true" />in devenv.exe.config file - Reinstalled Nuget Package Manager from VS > Tools > Extensions and Updates
- Reinstalled MVC4 from Microsoft
Then I repaired my VS installation from Control Panel > Add/Remove Programs and my issue was resolved. I don't know what went wrong but this certainly needs attention by Microsoft Guys. Hope my answer helps out somebody in need.
I was using VS12 and Updated to VS13, i was unable to create views and was getting the above error, I just updated Nuget Package Manager by going in Tool --> Extension and Updates and everything worked fine for me.
As I was having same issue, I realized that this workaround may work for some of us, but... In my case, it did not work. But changing the devenv.exe.config, removing the line
<NetFx40_LegacySecurityPolicy enabled="true" />
did the trick. Hope it helps those like me, need to have that anoying thing for some older solutions... ;)
