如果客户可以在试用期内免费使用您的应用，您可以将应用设计为在试用期内排除或限制某些功能。您还可以在客户购买应用之前启用仅在试用期间显示的功能，例如横幅或水印。让我们来看看如何将其添加到您的应用中：

If customers can use your app for free during a trial period, you can design your app to exclude or limit some features during the trial period. You can also enable features, such as banners or watermarks, that are shown only during the trial, before a customer buys your app. Let''s look at how to add this to your app:

要创建Windows应用程序的设置，您需要添加新的从解决方案项目。
此链接中显示的详细图示表示 [ ^ ]。
我假设您要在实际应用程序安装之前安装一些先决条件（第三方软件，如.net框架，Crystal报表，Sql服务器等）您可以按照以下步骤操作。
1）转到解决方案资源管理器。
2）右键单击安装项目。
3）点击属性。
4）点击先决条件按钮。
5）选择你的包裹。
6）选择第二个选项单选按钮，即从我的应用程序的相同位置下载先决条件。
7）构建应用程序。
现在你的根据您所需的先决条件构建。
试用期：您可以在安装应用程序时将安装日期存储在注册表中。每次你的应用程序启动时检查它是否完成365天，但它有一些陷阱。有关详细信息，请访问以下链接。

For creating setup of your windows application you need to add new project from solution.
The detailed pictorial representation shown in this Link[^].
I am assuming you want to install some prerequisites(Third party software like .net framework, Crystal reports, Sql server etc.) before your actual application''s installation you can follow below steps.
1) Go to Solution Explorer.
2) Right click on setup project.
3) Click on Properties.
4) Click on Prerequisites button.
5) Select your packages.
6) Below to that, Select second option radio button i.e. Download prerequisites from the same location as my application.
7) Build the application.
Now your build with your required prerequisites in it.
For Trial Period: You can store the installation date in the registry when your applications gets installed & checks every time when your application starts whether it completes the 365 days or not but it has some pitfalls. For more detail you can follow below links.
