    Web API Edition is a part of ComponentOne Studio Enterprise and follows the standard subscription model like all other ComponentOne products.

    Runtime license checks are done for Web API services, which means library requires a unique key to be validated at runtime. C1.Web.Api (for Web API 2.2) services use Development level license mode, while C1.AspNetCore.Api (for ASP.NET Core) services use Application level license mode.

    What all is included in a subscription of Studio Enterprise?

    A subscription of ComponentOne Studio Enterprise includes all updates, bug fixes and official releases for one year. For example, if you purchase 2015 v1, you are entitled to use versions 2015 v2, 2015 v3, 2016 v1 and all other versions released in between these versions. A subscription entitles you to unlimited, royalty-free app redistribution using any valid version of ComponentOne controls.

    How does Licensing Work?

    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.

    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?

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

    1. Visit
    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.
