Version question

[PhilDegler]

I am soon going to be developing a silverlight application using the silverlight API.  What versions of the following software are recommended assuming that the ARCGIS server is 9.3.1?

Visual Studio
Expression Blend
Silverlight
ESRI Silverlight API

Any help would be greatly appreciated

Visual Studio 2008
Expression Blend 3
Silverlight 3
ESRI Silverlight API 1.2

What sort of compatability issues could I potentially run into if I attempted to use the latest versions of the software I have listed against a 9.3.1 server?

I need to explain to my superiors why using the latest versions of VS, silverlight etc. is not a good idea if the customer is not yet upgrade to ARCGIS server 10.

Thanks for your initial reply, by the way 🙂

We try to make our API backwards compatible so it should work against ArcGIS Server 9.3.1.

However you if you don't upgrade to ArcGIS Server 10, you cannot take advantage of the new features in v10. http://help.arcgis.com/EN/arcgisserver/10.0/apis/rest/index.html

I think you plan to support ArcGIS Server 10 and up in the future, your best bet is to also get latest API, SL and VS.

Any version will do with Server 9.3.1, but as Jennifer mentioned, you won't be able to take advantage of a lot of the v2.0 features that relies on ArcGIS Server 10.-
