Search in frequently asked questions ## General ### What is ASP.NET Zero? ASP.NET Zero is a Visual Studio solution. It's built based on layered architecture and other software **best practices**. It provides a SOLID, strong and scalable solution **architecture**, pre-built **pages** and much more. If you have a business idea and want to build a web application, then you can take ASP.NET Zero as your base solution to **not waste your time** on building common requirements like user, role and permission management, audit logging, setting management, user profile management, localization and so on (see the [feature list](https://aspnetzero.com/Features)). It not only provides many **pre-built functionalities**, but also makes your daily development work easier by using a complete web application framework: [**ASP.NET Boilerplate**](https://aspnetboilerplate.com) It also supports multi-tenancy, subscription and payment systems if you want to create a **SaaS** application. It's built on **already-known tools** like ASP.NET Core, Entity Framework, Angular, React [and so on...](https://aspnetzero.com/features) It uses the [**Metronic**](https://themeforest.net/item/metronic-responsive-admin-dashboard-template/4021469) theme for the user interface. You get the **full source code** and can change it freely based on your business requirements! ### What are the main benefits of ASP.NET Zero? It provides a layered, well-defined and documented **architectural model**. So, your developers will know how to write code that follows best practices. The solution is **mature** and has solved most of the issues faced when creating an application from scratch. It provides many **pre-built functionalities** that are common to almost every application: login, user, role and permission management, audit logs, settings, user profile, multi-language, multi-tenancy and so on. Create a [demo](https://aspnetzero.com/demo) to see most of the UI. It's based on the open-source and community-driven **[ABP](https://aspnetboilerplate.com)** framework. It is actively used by thousands of developers and is continuously developed. It makes your daily development easier by providing base classes and infrastructure, and automates your repeated tasks. So, don't waste your time on common requirements, **begin to develop your business idea from the first day**. ### What's the relationship between ASP.NET Boilerplate and ASP.NET Zero? ASP.NET Zero is built by the team behind [**ASP.NET Boilerplate**](https://aspnetboilerplate.com). So, it's the best UI and application implementation of the framework. Everything in ABP can be directly used in ASP.NET Zero. All the documentation is valid for ASP.NET Zero too. Since ABP has a comprehensive documentation, it will help a lot while developing your application. [**ASP.NET Boilerplate**](https://aspnetboilerplate.com) website provides a free startup template to simply start with the framework. ASP.NET Zero is a production-ready enterprise-level application base. See the [comparison table](https://docs.aspnetzero.com/en/common/latest/Abp-Template-vs-AspNet-Zero) for differences between the free startup templates and ASP.NET Zero. ### How is ASP.NET Zero different from ABP Framework? They come from the same team at Volosoft, but they are separate products on different foundations. ASP.NET Zero is built on [ASP.NET Boilerplate](https://aspnetboilerplate.com) (the framework this FAQ calls "ABP") and ships as one complete solution: the ASP.NET Core backend, Angular, React and MVC & jQuery web UIs, a public website and a .NET MAUI mobile app, all as source code you own. [ABP Framework](https://abp.io) is the team's newer, modular framework - a rewrite, not a new version of ASP.NET Boilerplate - with its own commercial platform, modules and tooling at abp.io. Choose ASP.NET Zero when you want a finished application foundation in a single solution to build your product on; look at ABP Framework when you want to compose an application from modules or build a microservice system. ## License ### What are the 'product' and 'developer' counts in the license? Our licenses have **product count** restrictions. For example, if you buy a Regular license, you can use it to develop one real product/solution. You can create test/demo projects up to the number of products allowed by your license. You can also re-create (re-download) the same project whenever you need. However, you should buy higher licenses if you want to develop more than one product/solution using ASP.NET Zero. You can sell your product to any number of customers or deploy to more than one environment. No restriction here. ASP.NET Zero license also has a **developer count** restriction. Regular license allows up to 3 developers who are actively working on your ASP.NET Zero based solution. If you have a larger team, you should buy higher licenses. Notice that the license system only checks during development. It does not check on the production instance, because the license does not have a limit on deployment count. It also does not force you to be connected to the internet both during development and in production. ### Can I build and sell a SaaS product with ASP.NET Zero? Yes. The license covers developing your product; it does not limit how you run or sell it. You can host it as a SaaS for any number of tenants and customers and deploy it to any number of servers, and the license is never checked in production. ASP.NET Zero includes multi-tenancy, editions, subscriptions and payment integration for exactly this, and the Metronic theme license it includes covers SaaS use too. What you cannot do is redistribute ASP.NET Zero itself - for example publish it as open source or resell it as a starter kit. See the [license agreement](https://aspnetzero.com/Licenses/Eula) for the exact terms. ### Does it include Metronic license? ASP.NET Zero includes the full Metronic license. You can use Metronic with ASP.NET Zero under our terms and restrictions. For example, Metronic normally requires an Extended license for SaaS projects, but you can use it with ASP.NET Zero in your SaaS application without any additional cost. One restriction here: You cannot buy ASP.NET Zero and just use Metronic independently in your non-ASP.NET Zero based projects. You can only use Metronic in ASP.NET Zero. ### Does it include the full source code? Yes, we sell the source code. So, you can completely change it based on your requirements. There are two exceptions to that: 1. The solution uses many libraries, which are free and open source, as NuGet packages. Including all of their source code in the solution is not a good idea, because the size of your solution will be huge and you cannot update the libraries easily. However, if you need the source code of any library, you can just get it from its repository. [ABP](https://aspnetboilerplate.com/) framework is also like that and it's available in the [GitHub repository](https://github.com/aspnetboilerplate/aspnetboilerplate). So, there is no hidden code in that manner. 2. The solution also has a closed-source NuGet package that is used to protect ASP.NET Zero's [license rules](https://aspnetzero.com/Licenses/Eula). This closed source library has a few application-independent utility classes that are not subject to change for your application, but to make the application dependent on the licensing library. Notice that ASP.NET Zero's license control is done only during development and only during your license period. You can continue to develop and use the source code (even without the developer count restriction) after your license period ends. ### Can I use all Metronic components and themes in ASP.NET Zero? ASP.NET Zero uses [**Metronic**](https://themeforest.net/item/metronic-responsive-admin-dashboard-template/4021469) as the UI theme. Metronic is one of the world's most popular, strongest and richest UI themes, probably even the first. That's why we have chosen it. When you buy ASP.NET Zero, you will have access to **all Metronic theme layouts and components**. You can use all of them in your applications. ### What happens when the license period ends? ASP.NET Zero license includes 1-year upgrade and premium forum support. You will also have access to the private ASP.NET Zero GitHub repository so that you can track the changes, contribute to the code-base and open issues. After your license period ends, you can continue developing your application and using ASP.NET Zero for a lifetime. Besides, you can always update ASP.NET Boilerplate packages, since they are open-source projects (and will always remain as open-source). You will also be able to access to the documentation since it's public. On the other hand, your account will become passive and you will not be able to get ASP.NET Zero upgrades anymore, also you will not have access to the GitHub repository. Your premium forum membership will be ended. You cannot redeem any remaining project credits after your account is passivated. You cannot use Power Tools after the license period ends. You can extend your license by 1 more year for 50% of your purchased license's current price. There is no time limit on license extension, so you can extend your license by paying 50% of the current license price anytime you want. ### Can I upgrade to higher licenses in the future? Yes, you can upgrade to a higher license by just paying the price difference. Upgrades should be requested within the first 3 months of your license period. Your license period is automatically extended when you upgrade. You can use the license management page to extend your license. Send an email to info@aspnetzero.com if you need help. ### Do you have a trial plan? Since we sell the full source code, we are sorry for not having a trial plan. But we provide 30 days money-back guarantee - no questions asked! Try it... Doesn't fit your requirements? You'll be refunded in a couple of days. To have a quick view of what it looks like the UI, [create a demo](https://aspnetzero.com/demo) or watch the [explainer video](https://www.youtube.com/watch?v=OsSdNkwmC7I). For technical information, check out the [documents](https://aspnetzero.com/Documents). If you have any further questions, please don't hesitate to [contact us](https://aspnetzero.com/contact). ### What's a Product? An ASP.NET Zero product (project, solution) is a Visual Studio Solution that's generated from [aspnetzero.com](https://aspnetzero.com/). To create a product, you enter your project name (which will be the part of the namespace), you choose your frontend (Angular / React / jQuery) and download a Visual Studio Solution. This downloaded project is called a product... A CRM application, an ERP application or an online shopping website projects are different product examples. For a Regular License, you can generate a single product and you will have the complete source code of the product. Be aware that you are free to add new modules/web interfaces, integrate to 3rd party APIs, add reporting tools to your project without any limitation. There's no deployment restriction, you can publish your project to any number of servers. Notice that, the word "product" can also be used as "project" or "solution" in various places on the website. These have all the same meanings. ### What happens if I sell the applications with the source code or transfer it to my customer? If you sell the application with the source code, a new license must be purchased according to developer count of the your customer who are going to work on delivered project. If you transfer the project with the source code to your customer, you also need to transfer your ASP.NET Zero account to your customer. No additional license is required for this transfer. ### Can I add additional developer(s) or product(s) for my current license ? Yes, you can purchase additional developers ($299 each) or products ($999 each) for your existing license; they are extended together with your license. You can see purchase links on [License Management page](https://www.aspnetzero.com/LicenseManagement). ### What is the difference between renewing and upgrading? Renewing or extending your license allows you to access to the ASP.NET Zero support website and latest source code (bug fixes and enhancements) of ASP.NET Zero for 1 more year. Upgrading to a higher license allows you to create new project(s) and increase the developer count of your license. ## Development ### Where can I find documentation ? See https://docs.aspnetzero.com/ which is the main documentation website. ### Is it deployable to the cloud services? Yes, ASP.NET Zero is cloud agnostic. There's no vendor lock-in. You can publish it to Azure/AWS/Google Cloud/IBM Cloud/Alibaba Cloud or on-premise. ### How to upgrade existing applications when a new version is available? We can split updating into 2 parts: 1 - ASP.NET Boilerplate; the framework part. The framework can be easily updated since it's distributed on NuGet. Here's a list of all the [NuGet packages](https://www.aspnetboilerplate.com/Pages/Documents/Nuget-Packages) New releases are generally backward-compatible. If there is a breaking change, we will add it to the release notes and document how to migrate. You can upgrade these NuGet packages even after your license period ends, since they are open source. So, upgrading this part is easy. Just update the NuGet packages. 2 - ASP.NET Zero; the startup template part. Includes UI views and application services. This part is not developed as a 'closed' framework/library. Since different companies have very different needs, you will want to extend/change the UI for your needs. That's why we call ASP.NET Zero a starter kit/template: All the source code of ASP.NET Zero is in your hands, so you can freely modify it for your needs. In most cases, you don't have to upgrade if you are happy with your solution. You might even build the same feature yourself before us. If you like the new features, you should adapt the changes to your existing solution. In this case, the GitHub repository will help you much (https://github.com/aspnetzero/aspnet-zero-core, requires purchasing ASP.NET Zero to access). You can compare releases and copy the changed parts to your solution. For example, assume that we enhanced the Audit Logs page with new features and you want to get these new awesome features. If you did not change this page, you can directly replace your page and related classes. If you did change it, then you can see the changes on GitHub and merge the changes into your code. We also advise you to review each commit to check if it's needed for you, because some of them can be bug-fixes. You can also ASP.NET Zero's version [upgrade document](https://docs.aspnetzero.com/en/common/latest/Version-Updating) to learn how to upgrade your project with latest version of ASP.NET Zero. ## Payment ### What are the available payment options ?
