Deploying ASP.NET MVC4 App to GoDaddy Compiler issue - asp.net

Question

Have seen several posts about deploying MVC apps to GoDaddy. None of them seem to address the issue we are having. We have followed the advice about checking runtime versions, IIS pipeline modes, publishing and copy local to true on assemblies so all works on GoDaddy.Com.
The issue we are having is that when we try to visit the site we get a Group Policy exception because ASP.NET runtime is trying to invoke the C# compiler.
[Win32Exception (0x80004005): This program is blocked by group policy. For more information, contact your system administrator]
[ExternalException (0x80004005): Cannot execute a program. The command being executed was "C:\Windows\Microsoft.NET\Framework\v4.0.30319\csc.exe".........
We have gone through the publish settings and elected to precompile the site. That didn't fix the issue. Have looked at the site and there are no CS files deployed. The Global.asax file does reference a codebehind file. Since we precompiled the site we tried deleting the global.asax file and that doesn't fix the issue either.
Any thoughts would be great.

Answer 1

I have struggled with the same problem for months. And finally solved it. In the plesk on godaddy I changed the ASP.Net settings. First changed CAS-trustlevel to Full. Then I changed in the Web.config of my project the following:
Add trust level full to the system.web
Remove the compilers in the system.codecom
<system.web>
compilation debug="true" targetFramework="4.5.2"/>
<httpRuntime targetFramework="4.5.2"/>
<trust level="Full"/> <!-- Just add this to the webconfig -->
</system.web>
<system.codedom>
<!-- All is removed between the 2 tags-->
</system.codedom>
and that solved my problem.

Answer 2

You have to remove the compilation info from the web config and it will work.
In addition to precompiling (check the box in your publish settings), add the following to your Web.Release.config:
<system.web>
<trust level="Full" xdt:Transform="Insert" />
</system.web>
<system.codedom xdt:Transform="Remove" /> <!-- No compiling on server, GoDaddy blocks it. -->
UPDATE (1/27/2017):
It appears (at least on my account) that removing system.codedom is no longer required.

Answer 3

I had same issue on GoDaddy hosting.
To fix it follow these steps.
Step 1: Choose "Precompile during publish" in Web Deploy settings.
Step 2: <trust level="Full" /> in <system.web> in Web.config

This problem happens with a clean mvc 5 web project from visual studio 2015 template.
I contacted the godaddy support, let's see what they do.

Add >trust level="Full" />" under >system.web> section in Web.config
