Error when creating a Partial View in Visual Studio 2012 Express with Razor

Question

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.

restarting didn't work for me, see my answer at: http://stackoverflow.com/questions/14637632/exception-when-adding-a-view-to-mvc3/27259065#27259065 — mcfea, Dec 02 '14 at 21:14

Is simple... Just restart Visual Studio.

For anyone with VS2012 Update 3 , this is happening to me when I sometimes click on a method in a controller and click on "Add View" , but indeed the restart of visual studio does fix this. thx – Tom Stickel Jul 16 '13 at 05:52

Worked in VS 2019 for me as well – Code Slinger Oct 10 '19 at 20:21

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.

Your problem is outside of the 99% of the problems that solves the first principle of computer science: restarting. Sad. – Pablo Claus Feb 06 '15 at 03:30
@pabloker You're absolutely right, this truly took so much important time repairing visual studio installation – Manik Arora Feb 06 '15 at 05:57

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... ;)
