You can work on multiple Web API 2.2 applications using the same license. The licenses.licx file containing the licensing information would automatically be generated by the Visual Studio template based on the ComponentOne license present on the system. The contents of the license file are as shown below.

C1.Web.Api.LicenseDetector, C1.Web.Api

You can even distribute your application across multiple users without worrying about paying any royalty or user fees for distribution. This is a huge cost-saver and also makes embedding ComponentOne controls into applications easier as there are no licensing pre-requisites.

When you download and install ComponentOne products, you are presented with the chance to activate a license. If you would rather evaluate our tools before buying, you can skip the license activation process. At that time, you will have a 30-day evaluation period. During that period, you will be able to use all features of ComponentOne products. At the end of the 30-day period, you will not be able to build applications that include unlicensed ComponentOne controls.

You can purchase and activate a license at that point or you can request an evaluation key that will grant you another 30-day evaluation period. Once you have the evaluation key, you would activate it through the ComponentOne License Activation utility found in your ComponentOne Start menu.

How to purchase a license or request a 30-day evaluation key?

• License: You can purchase a license through our online store or by contacting our sales department. As soon as you purchase, a key will be emailed to you.
• Evaluation Key: You can get a 30-day evaluation key by contacting sales or through our website's My Account section (you will need an account to proceed with this option).

Complete the following steps to generate a 30-day evaluation key through our website:

1. Visit https://www.grapecity.com/componentone.
2. Open My Account and login or create an account. If you create an account, you must use the same email you used when you initially downloaded ComponentOne products.
3. Find your current evaluation listed under My Evaluations and click Extend Evaluation button.
4. You will receive an email with our key which you will then need to activate on your machine.

How to activate the key on your machine?

After you have received your license or evaluation key through email, complete the following steps to activate it on your machine.

1. Find the ComponentOne License Activation utility at the following location and open it:
   ($/Program Files (x86)/ComponentOne/C1StartMenu) .
2. Enter your key, choose an activation method, and follow the on-screen instructions.
   If you activate a 30-day evaluation key, your trial will proceed exactly as your previous trial did. If you activate a license key, you will be entitled to royalty-free perpetual use.

How to manually add the license file to the application?

1. In the Solution Explorer, right click the project and select Add | New Item. The Add New Item dialog appears.
2. In the Add New Item dialog, select C# | General and select Text File in the right pane.
3. Name the text file as licenses.licx.
4. Add the following to the text file:

   Licenses.licx	Copy Code
   C1.Web.Api.LicenseDetector, C1.Web.Api
