ASP.NET precompile error during publishing

64 bit PDFNet.dll works fine from a Website ASP.NET project but when attempting to use the publish feature with the pre-compilation option you may get the following error:

Could not load file or assembly 'PDFNet' or one of its dependencies. An attempt was made to load a program with an incorrect format. WebSite ASPNETCOMPILER 0

Getting the 64 bit PDFNet.dll to successfully publish with “Precompile during publishing” option enabled requires adding the following to publish profile in the App_Data folder:

Shell

<AspnetCompilerPath>C:\Windows\Microsoft.NET\Framework64\v4.0.30319</AspnetCompilerPath>
