asp.net mvc 4 - Clearscript files cannot be found on host

Question

Like a lot of others I'm receiving the following error when deploying my ASP.Net MVC application:

Cannot load V8 interface assembly; verify that the following files are installed with your application: ClearScriptV8-32.dll, ClearScriptV8-64.dll, v8-ia32.dll, v8-x64.dll

Clearscript was installed as part of an effort to transform less files on the fly for page requests.

I have tested my application locally in ISS Express and ISS without a hitch.

As suggested here http://clearscript3.rssing.com/chan-14849437/all_p12.html I've also included the missing code libraries as resources to my project.

ClearScriptV8-32.dll, ClearScriptV8-64.dll, v8-ia32.dll, v8-x64.dll are all included in a folder ClearScript.V8 in the bin folder. Removing this folder does not resolve the issue.

At my wits end. Any help is appreciated.

Answer 1

the cause is that asp.net load instantly all libraries in /bin directory. I added the following rule to ignore Clearscript assemblies, and it worked

<configuration>
    <system.diagnostics>
        <trace autoflush="true" />
    </system.diagnostics>
    <system.web>
        <compilation>
            <assemblies>

                <remove assembly="ClearScriptV8-64" />
                <remove assembly="ClearScriptV8-32" />
               ....
            </assemblies>
        </compilation>
