I had face the same issue but It is not an error, it is simply a warning; so your application should still compile. I used the following simple config file and the warning is still produced.

```
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup>
        <supportedRuntime
             version="v4.0"sku=".NETFramework,
             Version=v4.5"/>
    </startup>
</configuration>
```
