Product updates

During your active Standard Support subscription you can get and use all DotNetBrowser updates including patch, minor, and major versions for free.

DotNetBrowser updates include:

new features;
fixes and improvements;
support of the new .NET and operating system versions;
Chromium upgrades.

Help with the product use

Our support engineers will be in touch with you and consult on the use of the product, provide expert advice, answer all your questions regarding DotNetBrowser possibilities, and assist in troubleshooting different issues.

Assistance in troubleshooting

If you see an issue that happens only in a specific environment, and you cannot provide a minimal test application where it is reproducible, we are ready to assist in troubleshooting such issues.

We can analyze the logs, stack traces, crash dumps, thread dumps, set up a remote screen sharing session and try to figure out what’s going on. If possible, we will suggest some workarounds or figure out how to reproduce the issue on our side to debug the library and apply the fix.

We accept and fix only the issues we can reproduce. It is the only way we can create an automated test, apply the fix, and make sure that the fix solves the issue.

Considering feature requests

If you want DotNetBrowser to be extended with some new functions, you can send us a feature request. We will consider your feature request and let you know if we will proceed developing this functionality or not. If we decide not to proceed developing the feature we will explain why and suggest a workaround if it exists.

Preview builds

We will prepare a preview build personally for you as soon as we implement the feature or apply the fix.

Custom builds

Do you need a very specific custom feature which cannot be included into an official version? In terms of this service, you can request that we implement the feature on top of the latest official version and provide you with a custom build. We will work with you to better understand the feature you need, collect all the requirements, investigate and provide you with an estimate, implement the feature, prepare and deliver the custom build for you.

Priority feature development

If you don’t want to wait until the requested feature is implemented in one of the next versions, and you need it as soon as possible, you can use this service to increase the priority of the feature and get it sooner than the planned release date.

Video calls, remote sessions, and chats

Use the extended communication channels to get in touch with our support engineers. If necessary we can arrange a video or phone call, set up a remote working session, or use chats for more effective communication. This service is used as an additional option to our Standard Support subscription or in a combination with other Premium Services.

Consulting and expert advice

If you have an idea of a new great product, or you want to extend functionality of your existing product by integrating DotNetBrowser and you don’t know how to do it right or how to solve your specific case. Our experts can assist and help you find the best solution, reduce your costs and manage risk.

On-site consulting

If there’s a necessity to be on your site to gather the details about your project and collect the requirements to provide you with expert advice from our engineers, then we are ready to provide you with on-site consulting all over the world.

Official releases on demand

You can request to release an official version with the feature or fix you are interested in, without awaiting the planned release date.

Testimonials

What our clients say

“We have been using TeamDev’s DotNetBrowser for over five years. Every time I have had a question or issue, TeamDev has always been very helpful and accommodating with quick replies.”

Eric Gravitt

“Prior to integrating the DotNetBrowser product we were using chromium embedded framework directly and we were spending a good amount of time trying to understand the inner workings.

With DotNetBrowser all the complexity has been encapsulated and provided in an easy-to-use and extremely well documented framework.

The product is remarkably robust and still allows us to have total control without having to understand how it all fits together internally.”

John Wilson

“We migrated to TeamDev’s DotNetBrowser a few years ago and the process was smooth due to the well-designed API paired with its thorough documentation.

Any questions I had were readily answered by TeamDev staff who understood the issues better than I did, leading to rapid resolutions.”

James LaPenn

“TeamDev has been always helpful when we had any problems. They always keep updated their easy to use product DotNetBrowser. We’re glad to cooperate with them.”

Yasin Dokmecioglu

“Collaborating with DotNetBrowser has been a delightful experience. Their product is highly user-friendly, enabling me to effortlessly accomplish tasks.”

Penn Ye

“Working with the folks at TeamDev has been a pleasure, and their product is exceptional. Their software has allowed us to add functionality to our product that would have been impossible to implement. Their support team has consistently provided prompt and effective assistance, ensuring a smooth and seamless experience.”

Steven Amani

“We now use DotNetBrowser very successfully for several years as a core component of our digital signage and kiosk software FrontFace.

We are more than satisfied in regards to the rich set features provided, the outstanding stability of the component and the excellent and super-quick technical support provided by TeamDev!”

Joachim Schwieren

“I’ve worked with CefSharp with some success. The thing I like and appreciate about TeamDev is the support. With CefSharp I cannot reach out to any one as knowledgeable and helpful as your team. In the end it just takes me more time with CefSharp.

You’re always quick to respond with examples that make it all really easy for me to implement a solution.

The license cost is worth it, just for the support.”

Frequently asked questions

Technical questions

Do my users need to install Chrome?

No, all the required Chromium binaries are deployed with DotNetBrowser. You do not need to install Google Chrome to work with DotNetBrowser.

How often do you upgrade Chromium?

We follow Chromium schedule and start upgrading Chromium to the latest stable release as soon as it is available for download. Upgrading to a new Chromium version usually takes 3‑4 weeks depending on the number of changes in the latest Chromium version.

Can you backport a fix from the latest version to the version I currently use?

No. All the fixes, improvements, new features, new .NET and operating system versions, and Chromium upgrades are implemented on top of the latest (mainstream) version only. We do not apply or backport the fixes and features on top of the previous versions.

How many employees of my company can contact support?

If you have an Indie license we will create one account in DotNetBrowser Help Center for the license holder.
2 accounts are created for the employees of the Project license holder.
Enterprise licensees can obtain up to 4 accounts for the company’s employees.

Every person with an account in our system can contact the technical support.
