Modify a .Net Applications .exe.config file Settings Value via Powershell

I have a .Net console application which has an App.Config / MyApplicationConsole.exe.config file. This one contains settings set via the properties manager of VS, basically looking something like this:

<?xml version="1.0"?>
<configuration>
  <configSections>
    <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">
      <section name="My.Applications.Namespace.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
    </sectionGroup>
  </configSections>
  <applicationSettings>
    <My.Applications.Namespace.Properties.Settings>
      <setting name="SettingsKeyABC" serializeAs="String">
        <value>SomeOtherValue</value>
      </setting>
      <setting name="SettingsKeyXYZ" serializeAs="String">
        <value>True</value>
      </setting>
    </Siemens.Med.CTE.PMP.Applications.JobExecutor.Properties.Settings>
  </applicationSettings>
  <system.diagnostics>
    <trace>
      <listeners>
        <add name="Gibraltar" type="Gibraltar.Agent.LogListener, Gibraltar.Agent" />
      </listeners>
    </trace>
  </system.diagnostics>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0" />
  </startup>
</configuration>

Now what I want/need to do is modify the ("True") value for the "SettingsKeyXYZ" setting, preferably via powershell (as my colleague set up). Does anyone know how to do this? All I found were sample for Web.Configs which seem a tad different than the ones created by VS.

First, The xml text is not valid. Where's the closing tag of line 10 tag (My.Applications.Namespace.Properties.Settings). I changed line 10 to match the closing tag.

Load the file (as xml), you must put the 'My.Applications.Namespace.Properties.Settings' tag in quotes otherwise powershell will try to parse each value between the dots as a tag), update the value to False and then save the file.

[xml]$xml = Get-Content c:\App.Config
$xml.configuration.applicationSettings.'My.Applications.Namespace.Properties.Settings'.setting.value='False'
$xml.Save('c:\App.Config')
