If we wanna to run an application under admin privilege, we can configure it in app.menifest

<asmv1:assembly manifestVersion="1.0" xmlns="urn:schemas-microsoft-com:asm.v1"
xmlns:asmv1="urn:schemas-microsoft-com:asm.v1" xmlns:asmv2="urn:schemas-microsoft-com:asm.v2"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <assemblyIdentity version="1.0.0.0" name="MyApplication.app"/>
  <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
    <security>
      <requestedPrivileges xmlns="urn:schemas-microsoft-com:asm.v3">
        <!-- UAC Manifest Options
            If you want to change the Windows User Account Control level replace the requestedExecutionLevel node with one of the following.
            
            <requestedExecutionLevel  level="asInvoker" uiAccess="false" />
            <requestedExecutionLevel  level="requireAdministrator" uiAccess="false" />
            <requestedExecutionLevel  level="highestAvailable" uiAccess="false" />
        -->
        <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
      </requestedPrivileges>
    </security>
  </trustInfo>
</asmv1:assembly>

Check whether application runs under admin privildge,

            System.Security.Principal.WindowsPrincipal principal = new System.Security.Principal.WindowsPrincipal(identity);  

            if (principal.IsInRole(System.Security.Principal.WindowsBuiltInRole.Administrator))  
            {  
               // processing
            }
