ExtJs in a ASP.NET web application

I would like to understand if it is possible to use ExtJs as is (without any modification) in a web application built with asp.net server technology. practically I would like to develop a Web application with 开发者_JAVA百科ASP.NET using ExtJs as is, but I don't know if I can use it without problems of licensing. Thanks in advance Luke

If you are asking about it from the technical perspective, see my answer here.

If you are asking about licensing specifically (and I'm assuming you're asking about GPL) you can use it as long as your application is compatible with GPL. If you have any doubts you should email licensing@sencha.com. See also this question for some insight about Ext + GPL.

You should also look into Ext.NET if you haven't already -- they are the official Sencha .NET partner and offer the same dual licensing model as Ext JS.

EDIT: Any answer you get here will just be someone's opinion -- it will not be a basis for you to defend against an infringement claim by Sencha that you have violated their licensing. You really should contact the company if you have any doubts -- see my answer here, including the comments.
