title: PresentationFramework.pdb not found
body: <p>Suddenly Visual Studio says that PresentationFramework.pdb is not found.
  The InnerException says that something is wrong with line 4 in the Application.exe.config:</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;configuration&gt;
    &lt;configSections&gt;
      &lt;sectionGroup name="userSettings" Type="System.Configuration.UserSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"&gt;
        &lt;section name="Application.Properties.Settings" Type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" allowExeDefinition="MachineToLocalUser" requirePermission="false"/&gt;
      &lt;/sectionGroup&gt;
    &lt;/configSections&gt;
    &lt;startup&gt;
      &lt;supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5"/&gt;
    &lt;/startup&gt;
    &lt;userSettings&gt;
      &lt;Application.Properties.Settings&gt;
  
      &lt;/Application.Properties.Settings&gt;
    &lt;/userSettings&gt;
  &lt;/configuration&gt;
  </code></pre>
  
  <p>Reading the Presentation Framework or clean and rebuild project doesn't work.</p>
  
  <p>Problem solved I just had to rename <code>Type</code> to <code>type</code>.</p>
