Hi John,   If you have a moment, I have a question regarding an ArcGIS Server site which appears to be owned by the Maryland Department of Transportation: http://170.93.143.161/arcgis/rest/services There are a couple feature layers in a map service that have an extent where min\max x\y are NaN and spatial reference is set to 26985.  Example: http://170.93.143.161/arcgis/rest/services/CHARTMap/CHART_Public_PC/MapServer/1 I've been unable to reproduce this behavior where min\max x\y are NaN.  Do you know how this data was prepared to exhibit these properties? Thanks -Rex  ... View more

Hi Karen,    A client access policy file must be present at the root of a web server.  If IIS, often the physical folder that cooresponds with the web site root is c:\inetpub\wwwroot.  If you're using the web server included with ArcGIS Server, the physical folder that cooresponds with the web site root may be c:\program files\arcgis\server\framework\runtime\tomcat\contents\rootapp.  Here's some additional information on working with service across domain boundaries in Silverlight: http://msdn.microsoft.com/EN-US/LIBRARY/CC197955(VS.95).ASPX Hope this helps, -Rex ...

Tracy,    The current resource center for the ArcGIS API v3.0 for Silverlight is available here: http://resourcesbeta.arcgis.com/en/webapis/silverlight-api/community/index.html. The current download version is 3.0 prerelease, with 3.0 final coming in June.   Prerelease only targets Silverlight 5.  The interactive SDK available on this site targets Silverlight 5.  As Dominique stated, the issues you reported are only present when using the Silverlight 4 runtime.  Since the problem is outside the ArcGIS API (Silverlight 4, IE & FF browsers), we are unable to fix it.  With this in mind, you have the option of targeting Silverlight 5 with v3.0 pre-release or updating your browser to IE9 (although this issue is not resolved in the latest FF browser - 12.0).  Hope this helps, -Rex ...

Thanks for reporting this.  The link will be fixed shortly.  In the meantime, you can get to the sample page with the correct link here: http://help.arcgis.com/en/webapi/wpf/help/index.html#/Interactive_SDK_samples/01n70000001m000000/ ... View more

Are you hardcoding the culture in the Silverlight application before deploying to the web server or trying to discover the users culture and set at runtime?   Side note, the ArcGIS API does not include localized resources for Tamil (ta).  Also, have you changed any globalization settings in IIS? http://technet.microsoft.com/en-us/library/cc725971(WS.10).aspx ...

matthewb-  The installer is looking for the Silverlight tools for Visual Studio 2010 to be installed. Since it's not required for VS2010 sp1, the templates are not showing up in the install.  We should have this resolved in 2.2.  In the meantime you can get the standard and showcase template online here: http://help.arcgis.com/en/webapi/silverlight/samples/TemplateGalleryWeb/start.htm ...

Thanks for the additional info.  The cross domain files you attached will only impact services on a site on which they are present.  For example, when accessing sampleserver1.arcgisonline.com, the clientaccesspolicy.xml here: http://sampleserver1.arcgisonline.com/clientaccesspolicy.xml   If you have placed the cross domain files you attached on a web server hosting your ArcGIS Server services, I would encourage you to start with a copy of those hosted on ArcGIS Online servers (they are wide open) to make sure you can access services, then begin the process of restricting if needed.  In any case, if you're trying to load a map service on sampleserver1.arcgisonline.com and it's not working (as in your initial post) that's not likely related to a cross domain file.  Can you install Fiddler and trace the requests\responses between your client and sampleserver1 (the Dynamic map sample in the interactive SDK)?   You can install Fiddler from here: http://www.fiddler2.com/fiddler2/version.asp  Let me know if you see any errors with requests to sampleserver1. ...

The error message you're seeing appears anytime there is a problem communicating with a remote server (it mentions the most common reason, missing a clientaccesspolicy.xml or crossdomain.xml).   If you're trying to hit an ArcGIS online server or server hosted by Esri, this shouldn't be a problem.   There may be an issue retrieving service metadata or an image remotely due to client restrictions, as you mention.  Before we start diving into that, try the following code in a page and see if you encounter a problem.  You should see a 300x300 pixel map image in the middle of the app:     <Grid x:Name="LayoutRoot" Background="Blue">         <Image x:Name="MyImage"                Width="300"                Height="300"                Source="http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Specialty/ESRI_StateCityHighway_USA/MapServer/export?bbox=-183%2C9%2C-61%2C80&bboxSR=4326&size=300%2C300&format=png24&f=image" />     </Grid> ...

This is more a question for Microsoft than Esri.  As long as Microsoft supports the tools that are used to develop and use Silverlight applications on Windows XP, Esri will continue to support Silverlight in the same capacity.   You can view the latest system requirements for ArcGIS Silverlight developers and clients here: http://help.arcgis.com/en/webapi/silverlight/help/index.html#/System_requirements/01660000000t000000/ That said, if you have the opportunity to move to Windows 7 now, I recommend making the move. ...

Not sure why serverapps.esri.com went down last Friday, but it's been up now since Friday evening without incident.   We'll keep an eye on it. ... View more

SR-    It's not clear from your description of the problem that this is related to the ArcGIS API for Microsoft Silverlight or WPF.   Can you provide additional details on how the API is being used in a way that impacts this scenario?   You may want to try the ArcSDE and geodatabase forum for issues dealing with transactions and databases: http://forums.arcgis.com/forums/32-Geodatabase-amp-ArcSDE ...

The proxy page included with the Silverlight API is a streamlined/enhanced version of the one included with the JavaScript API.  Basically generating the request and processing the response have been streamlined for the Web APIs.  Plus the proxy included with the Silverlight API supports secured services using tokens (long and short term) and http/windows authentication.  The JavaScript API proxy only supports long term tokens.  1) Yes.  As far as redirecting requests is concerned, the proxies are basically the same. 2) The Silverlight API proxy sets the content type of the request (if a POST) to "application/x-www-form-urlencoded" because its only been designed to support the use of a proxy (e.g. ProxyUrl) within the Web APIs.   Since POSTed requests from the Web API to the proxy always contain text, this content type will work.  However if you wanted to use the proxy to upload a file, you'd probably want to go with multipart/form-data.  Of course you can try to set it on the fly like in the JavaScript API.   Keep in mind you can modify the proxy at will; it only provides a workable starting point to support the use of a proxy in the Web APIs.  Ideally at some point in the future the proxies will be synchronized. ...

Unfortunately the source code for the Template Gallery is not available at this time.  We'll consider providing this in the future.  In the meantime you may want to take a look at some cover flow implementations in Silverlight (e.g. http://silverlightcoverflow.codeplex.com/). ... View more

Ravi-    The minimum version of the Silverlight runtime plug-in has been updated to reference 4.0.50401.0.   You should be able to load the Interactive SDK now without installing a newer version of the Silverlight runtime. ... View more

This issue has been resolved.   You should be able to download the templates from the ArcGIS Silverlight resource center at this time. ... View more
