How can I use the “Precompile during publishing” flag on a VS2013 x64 project? No matter what I do, it fails to publish because it insists on using the x86 ASPNETCOMPILER.
I think I used to have this working in VS2012, but after upgrading to VS2013 it is no longer working.
I recall the fix involving changing a text file related to MSBuild but I honestly don’t know very much about it so it’s a little hazy.
Any help is greatly appreciated. Thanks!

Method 1
This seems to be a bug in Visual Studio 2013.
Microsoft Connect – Precompile error when using X64 platform
The workaround listed there works and is to add the following xml in the Project/PropertyGroup xml tag to the publish profile (located in the PropertiesPublishProfiles directory of your project).
<AspnetCompilerPath>C:WindowsMicrosoft.NETFramework64v4.0.30319</AspnetCompilerPath>
I was getting this build error before applying the above workaround:
“Could not load file or assembly ‘****’ or one of its dependencies. An attempt was made to load a program with an incorrect format.” – ASPNETCOMPILER
Method 2
Still an issue in Visual Studio 2015 Update 3…
Fix: Open the csproj file of the project in your favourite text editor.
Locate:
<MvcBuildViews>true</MvcBuildViews>
Add the following below it:
<AspNetToolPath Condition=" '$(Platform)' == 'x64'">$(windir)Microsoft.NETFramework64v4.0.30319</AspNetToolPath>
Locate:
<Target Name="MvcBuildViews" AfterTargets="AfterBuild" Condition="'$(MvcBuildViews)'=='true'" > <AspNetCompiler VirtualPath="temp" PhysicalPath="$(WebProjectOutputDir)" /> </Target>
Amend the AspNetCompiler line as follows:
<AspNetCompiler VirtualPath="temp" PhysicalPath="$(WebProjectOutputDir)" ToolPath="$(AspNetToolPath)" />
