Hi,

i installed ASP.NET 3.5 Extensions Preview  http://www.microsoft.com/downloads/details.aspx?FamilyId=A9C6BC06-B894-4B11-8300-35BD2F8FC908&displaylang=en to use the build in feature AJAX History, which can enabled in the Scriptmanager.

I adapt my existing ASP.NET applications and it works fine, but just lokal.
When i publish the application i got an error, that the assembly System.Web.Extensions, Version=3.6.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35 could not befound.

Framework 3.5 is on the webserver already installed. Is a installation (ASP.NET 3.5 Extensions Preview) on the webserver also requiered, to get this work?

Or does a other way exist (including a assembly in the bin folder of the application)?

Thank you!
Melbu
