Can''t build project without license?

I have a team of 12 engineers working in the same code base, but only 2 of the engineers will be using the XlsIO library. They're currently using the demo version and it's working out well except that the other engineers can no longer build the project that contains references to the Syncfusion assemblies because they did not install the demo product.

My question is, will I need to purchase 12 licenses when only 2 of my engineers will be using the library? I also have the same problem on our automated build server. Will it require a license too? Buying 12 licenses for 2 engineers seems excessive.

Thanks very much for your interest in Essential XlsIO, and apologies for the delay in getting back to you. We license on a per-developer basis and charge no runtimes, royalties, or server deployment fees. A license will be needed for each developer who installs our components on their machine. We are happy to offer volume discounts to teams in need of a number of licenses.

Please email salessupport@syncfusion.com and let us know your location and whether you'd like access to the source code for Essential XlsIO. With that information, we'll route your inquiry to the appropriate account manager and a custom quotation will be prepared.
