Asp.Net MVC with Javascript Viewengine for serverside rendering - BuildError on server

Question

I'm using : https://github.com/Buildstarted/Javascript.ViewEngines as additional Viewengine.

This way i can server side render javascript, react, angular, ... ( it worked before)

For this i need to include a couple of dll in the root directory ( which is weird, but always done it like this)

The files are:

• ClearScriptV8-32.dll

• ClearScriptV8-64.dll

• v8-ia32.dll

• v8-x64.dll

When running it locally ( on 2 dev computers). Everything runs OK. The problem starts when i publish to either Azure or a "Web Deploy" on my own server.

My own publish gives me this:

Could not load file or assembly 'ClearScriptV8-32' or one of its dependencies. An attempt was made to load a program with an incorrect format.

Azure also: Could not load file or assembly 'ClearScriptV8-64' or one of its dependencies. An attempt was made to load a program with an incorrect format.

Sounds like you need to enable 32-bit applications since that's the type of library it's not able to load.

From that link, create a startup file that looks like:

%windir%\system32\inetsrv\appcmd set config -section:applicationPools -applicationPoolDefaults.enable32BitAppOnWin64:true

Then update your Window Azure Service Definition file to include start up task

<Startup>
 <Task commandLine="Startup.cmd" executionContext="Elevated" taskType="simple">
 </Task>
 </Startup>

Make sure that the Startup.cmd file is part of your Web Role application and set its property “Copy Local to True”
