    <system.web>
    <compilation debug="true" strict="false" explicit="true" targetFramework="4.5">
    <assemblies>
    <add assembly="ExifLib, Version=1.7.0.0, Culture=neutral, PublicKeyToken=30284005913968db, processorArchitecture=MSIL"/>
    </assemblies>
    </compilation>
    </system.web>
    </configuration>

    %>


    You will then be able to run your ExifLib website on your server.
