Silverlight 4 Support and ArcGIS 9.3.1

[HyrumErnstrom]

I'm confused about what is supported in what environment.

I know Silverlight 3 and ESRI SDK 1.1 and ArcGIS Server 9.3.1 work together.

I know Silverlight 4 and ESRI SDK 2.0 beta and ArcGIS Server 10.0 work together.

Will Silverlight 4, ESRI SDK 2.0 beta and ArcGIS Server 9.3.1 work together.

What about Silverlight 4, ESRI SDK 1.1 and ArcGIS Server 9.3.1?

What about Silverlight 3, ESRI SDK 1.1 and ArcGIS Server 10?

I'm working on starting a new project with Feature Layers and the client won't be going to ArcGIS Server 10.0 for probably another year. I trying to figure the best way to start the project so in a year when they go to ArcGIS Server 10.0 it still works but will work in ArcGIS Server 9.3.1.

- Will Silverlight 4, ESRI SDK 2.0 beta and ArcGIS Server 9.3.1 work together.
Yes

- What about Silverlight 4, ESRI SDK 1.1 and ArcGIS Server 9.3.1?
Yes it should (v1.1 is not officially supported/tested for SL4)

- What about Silverlight 3, ESRI SDK 1.1 and ArcGIS Server 10?
Yes it should (v1.1 is not officially supported/tested for SL4)

However, why are you not using at least v1.2 ?

[HyrumErnstrom]

You are right I meant version 1.2. Will 1.2 be tested by ESRI?

We are not aware of any issues using v1.2 with Silverlight 4.
