Does useLegacyV2RuntimeActivationPolicy work in class library projects?

Question

My project setup looks like this:

My application (4.0) --> My class library (4.0) --> 3rd party library (2.0.50727)

My application's app.config looks like this:

<?xml version="1.0"?>
<configuration>
  <startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
  </startup>
</configuration>

Yet when trying to launch the application, I receive the dreaded FileLoadException:

Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.

The respective third-party library is "System.Data.SQLite" v1.0.60.0. Is it necessary to enable the "useLegacyV2RuntimeActivationPolicy" attribute for my class library as well? How would I do that?

Thanks in advance for your help and best regards

Figured it out by now. I did not copy the resulting .exe.config file along with my .exe -.- ... Entirely my fault, sorry about this.
