ArcGIS 10 with Silverlight 3.

[SaurabhDasgupta]

Hi All,
       I am using ArcGIS Server 10. Is it possible to work with Silverlight 3 to develop the WEB application in visual studio 2008 SP1. I learnt from ArcGIS Resource center that ArcGIS Server 10 only supports some enhancements compared to ArcGIS Server 9.3.1 while working with Silverlight 4but no where written as it is really possible to use Silverlight 3 with ArcGIS Server 10. Also what version of Silverlight api should I be using for the said configuration.

Thanks in advance.

Look under "Requirements" at following URL

http://help.arcgis.com/en/webapi/silverlight/help/index.html#/Installation/016600000005000000/

It is mentioned clearly that only Silverlight V 4 is supported.

Only Silverlight v1.2 and v1.1 uses Silverlight 3, and those versions doesn't support the new features that ArcGIS Server 10.0 provides.

If you can't use SL4 because you only have access to VS2008, you can use the free VS2010Express edition to develop Silverlight 4 apps with.

Here's basically what the version requirements were:
v1.0: Silverlight 2 and ArcGIS Server 9.3
v1.1-1.2: Silverlight 3 and ArcGIS Server 9.3.1
v2.x: Silverlight 4 and ArcGIS Server 10.0
The following are unreleased but currently planned versions:
v3.0b1: Silverlight 4 and ArcGIS Server 10.1beta1
v3.0b2: Silverlight 4 or 5 and ArcGIS Server 10.1beta2
v3.0: Silverlight  5 and ArcGIS Server 10.1

Note: In most cases you can still use for instance v3.0 with a 9.3 server, and you can use v1.0 with a 10.1 server, but of course you can only take advantage of features that both versions support.
