<entryPoint> Element (ClickOnce Application)

Identifies the assembly that should be executed when this ClickOnce application is run on a client computer.

<entryPoint
   name
>
   <assemblyIdentity
      name
      version
      processorArchitecture
      language
   />
   <commandLine
      file
      parameters
   />
   <customHostRequired />
   <customUX />
</entryPoint>

The entryPoint element is required and is in the urn:schemas-microsoft-com:asm.v2 namespace. There may only be one entryPoint element defined in an application manifest.

The entryPoint element has the following attribute.

Attribute

Description

name

Optional. This value is not used by .NET Framework.

entryPoint has the following elements.

Required. The role of assemblyIdentity and its attributes is defined in <assemblyIdentity> Element (ClickOnce Application).

The processorArchitecture attribute of this element and the processorArchitecture attribute defined in the assemblyIdentity elsewhere in the application manifest must match.

Required. Must be a child of the entryPoint element. It has no child elements and has the following attributes.

Attribute

Description

file

Required. A local reference to the startup assembly for the ClickOnce application. This value cannot contain forward slash (/) or backslash (\) path separators.

parameters

Required. Describes the action to take with the entry point. The only valid value is run; if a blank string is supplied, run is assumed.

Optional. If included, specifies that this deployment contains a component that will be deployed inside of a custom host, and is not a stand-alone application.

If this element is present, the assemblyIdentity and commandLine elements must not also be present. If they are, ClickOnce will raise a validation error during installation.

This element has no attributes and no children.

Optional. Specifies that the application is installed and maintained by a custom installer, and does not create a Start menu entry, shortcut, or Add or Remove Programs entry.

<customUX xmlns="urn:schemas-microsoft-com:clickonce.v1" />

An application that includes the customUX element must provide a custom installer that uses the InPlaceHostingManager class to perform install operations. An application with this element cannot be installed by double-clicking its manifest or setup.exe prerequisite bootstrapper. The custom installer can create Start menu entries, shortcuts, and Add or Remove Programs entries. If the custom installer does not create an Add or Remove Programs entry, it must store the subscription identifier provided by the SubscriptionIdentity property and enable the user to uninstall the application later by calling the UninstallCustomUXApplication method. For more information, see Walkthrough: Creating a Custom Installer for a ClickOnce Application.

This element identifies the assembly and entry point for the ClickOnce application.

You cannot use commandLine to pass parameters into your application at run time. You can access query string parameters for a ClickOnce deployment from the application's AppDomain. For more information, see How to: Retrieve Query String Information in an Online ClickOnce Application.

The following code example illustrates an entryPoint element in an application manifest for a ClickOnce application. This code example is part of a larger example provided for the ClickOnce Application Manifest topic.

<!-- Identify the main code entrypoint. -->
<!-- This code runs the main method in an executable assembly. -->
  <entryPoint>
    <assemblyIdentity 
      name="MyApplication" 
      version="1.0.0.0"
      language="neutral"
      processorArchitecture="x86" />
    <commandLine file="MyApplication.exe" parameters="" />
  </entryPoint>
