推荐答案

adding the following lines to the app.config seems to fix the problem:<br />
<br />
    <startup useLegacyV2RuntimeActivationPolicy="true"><br />
         <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/><br />
<br />
     </startup>

adding the following lines to the app.config seems to fix the problem:

<?xml version="1.0"?>
<configuration>


<startup useLegacyV2RuntimeActivationPolicy="true">
  <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>

</startup>
</configuration>
