Run .NET application as administrator

Question

Since Vista & windows 7 came out some of my .NET application has started throwing security exceptions.

I've noticed that some applications (i.e. my antivirus, control panel) have a small shield and when I run these applications administrator privileges are automatically requested from me by windows.

I know that as a user I can set the application to run as administrator but that's not good enough because if the application will run without privileges it would crash on my users machines.

Is there a way to tell windows (programmatically) I want the application to run with administrative privileges?

Create an application manifest, set the requestedExecutionLevel to requireAdminstrator:

Example (generated by VS when you add Application Manifest):

<?xml version="1.0" encoding="utf-8"?>
<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" />

            If you want to utilize File and Registry Virtualization for backward 
            compatibility then delete the requestedExecutionLevel node.
        -->
        <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
      </requestedPrivileges>
    </security>
  </trustInfo>
</asmv1:assembly>

If you add this to a Visual Studio application project, it will be embedded into your assembly when you compile.

You need to mark your app as requiring admin privileges in the application manifest. Here's an article from MSDN Magazine that explains the process.

You should add an application manifest to your application, and configure it to request administrator privileges. See here: http://www.professionalvisualstudio.com/blog/2007/10/05/enabling-your-application-for-uac-on-vista/
