I have 100 developers but only 5 of them will be creating custom aspects. How many licenses should I purchase?
Everybody who modifies and builds code that has aspects needs a license. If the 100 developers modify the code that uses the aspects created by the 5 senior developers, you will need 100 licenses.
I have 100 developers but only 5 of those will create code that uses aspects. The others will build the code but not modify it. How many licenses should I purchase?
Everybody who modifies and builds code that has aspects needs a license. In this case, only 5 developers modify the code that has aspects, so you only need to buy 5 licenses.
Can I use PostSharp Essentials for commercial products?
Yes. You can build commercial products using PostSharp Essentials and redistribute them. Express Edition contains all the features of PostSharp Ultimate, however, the number of types to which you can apply aspects is limited to 10 per project or 50 per solution.
What does Maintenance Subscription include?
Maintenance Subscriptions provide free updates, including bug-fixing and major releases, during the duration of the subscription. Note that bug-fixing releases will not be available without a maintenance subscription. The subscription also includes web-based support and a limited number of e-mail premium support cases.
Can I order a multi-year maintenance subscription?
Yes. We provide multi-year maintenance subscription plans on PostSharp Professional and PostSharp Ultimate. When you select to buy one of these products on our Purchase page, you will be directed to our Support Plan page where you can choose from 1, 2 or 3 years of maintenance subscription which includes free updates, bug fixes and web-based support. Visit our purchase page to choose your subscription.
Do we need a license for our build server?
No. Build servers don’t need their own license.
Do we need to install a license on our build server?
Normally no. PostSharp will detect that it runs under a build server, and won't enforce licensing. In case that PostSharp fails to detect the build server, you can install any license key on the build server using the utility PostSharp Settings. Learn more about using PostSharp on a build server in the documentation.
Do you offer site licensing?
Contact us for more details.
How does the concurrent-developer licensing model work?
You need a license if you create or modify code using PostSharp. If you only build code that is using PostSharp, you don't need to purchase a license. The key is to determine how many developers are likely to create or modify code using PostSharp and buy enough licenses to cover that number.
Commercial Licenses are floating and allow for use on any computer, operating system, and by any developer within a legal entity, provided that the total number of users never exceeds the number of purchased licenses within a 24-hour period. A single user may use maximum 2 different computers during a 24-hour period.
Will my PostSharp license expire after the end of the maintenance subscription?
No. All licenses are perpetual. The maintenance subscription only determines which version of the product you are allowed to use. If you are allowed to use a version one day, it will work every day. Actually, the build date of the product release needs to be within the maintenance period.
Can I amend or modify the License Agreement?
Some amendments are routinely accepted for orders of a significant size. Other amendments need to be reviewed by our lawyers. Please contact us for more information.
How is the concurrent license enforced?
PostSharp periodically uploads usage data to our servers and these are analyzed for license compliance.
Is it possible to disable license audit?
Established companies can ask to opt out from license audit. Please contact us for more information.
Does your software require a connection to the Internet?
No. PostSharp will work even if fully disconnected from the network.
Where can I find the complete text of the License Agreement?
My application has a dependency to PostSharp.dll. Do I need a redistribution license?
No. PostSharp licenses allow for royalty-free redistribution of components that need to run on end-user devices. These include PostSharp.dll and runtime libraries. Please contact us if you want to discuss a specific situation.
Is it possible to get a PostSharp Essentials company license for our whole team?
No. Unlike the commercial editions of PostSharp, free PostSharp Essentials licenses are named-user licenses and thus require every developer to check out their own license. If you need company licensing, choose PostSharp Professional or PostSharp Ultimate edition.
