.NET configuration file - Do I need to include it in installer?

Question

I have a C# application MyApp.exe that targets .NET 3.5. In order to support other versions, I used MSDN instructions, and created a config file MyApp.exe.config, with the following content:

<?xml version="1.0"?>
<configuration>
  <startup>
    <supportedRuntime version="v4.0"/>
    <supportedRuntime version="v2.0.50727"/>
  </startup>
</configuration>

My question is what should I do with this file? Do I need to include it in the installer and put near the exe file on the target computer? I couldn't find any instructions about it.

Yes. This file needs to exist next to the installed exe post-deployment.

Most installers that understand .NET deployment will automatically handle this for you, so it's likely you won't need to "do" anything special (other than verify it got copied across correctly.)
