<entryPoint> Element 

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


The entryPoint element is required and is in the asm.v2 namespace. There may only be one entryPoint element defined in an application manifest.

The entryPoint element has the following attributes.

Attribute Description


Required. Identifies the main or function entry point.


Required. The dependent assembly for the entry point.

entryPoint has the following elements.

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

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


Required. A local reference to the startup assembly for the ClickOnce application.


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.

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 a ClickOnce Application.

The following code example illustrates entryPoint elements 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. -->
<commandLine file="Notepad.exe" parameters="run" />
