Ben - Less than one quarter of the samples in the current Interactive Silverlight SDK operate in the WGS84 spatial reference.  While map content in WGS84 tiled services on ArcGIS Online is not being updated, and some are being retired, the functionality demonstrated in the Silverlight samples remains valid.  In fact, in some cases working in geographic coordinates has provided a more cognitive example for understanding functionality (e.g. manually creating graphics). That said, we are and have been updating samples periodically to reference basemap layers in Web Mercator.  This will continue where appropriate.  The Address Matching samples you mention in this post have been updated to use a Web Mercator basemap.  Unfortunately the locators hosted by ArcGIS Online are still operating on ArcGIS Server 9.3.1 servers, so the simplest solution is not yet available when using them (merely setting the output spatial reference for the locator task).  Hope this helps. ...

Unfortunately there is not a video for Silverlight or JavaScript specifically, but the steps for setting up a �??data extraction�?� service are the same regardless of the client API.   We host a sample data extraction service (actually a GP and Map service) here: http://sampleserver4.arcgisonline.com/ArcGIS/rest/services/HomelandSecurity.  We'll consider adding a sample that uses this service to the interactive SDK.  In the meantime, we do host a similar sample here: http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#ClipFeatures.  You should be able to gleen what is necessary for consuming an async data extraction GP service from that sample.  The data for this sample is included with the ArcGIS .NET SDK under: <ArcGIS Developer Kit install directory>/Samples/data/GP/RunClip/USA_data_ClipTools and <ArcGIS Developer Kit install directory>/Samples/data/USA/ -Rex ...

Can you generate another install log now that the vbscript.dll is registered?   Send it to me via email at rhansen@esri.com  Thanks ... View more

From the command line, run regsvr32 C:\windows\system32\vbscript.dll. if it registers successfully, run the setup again. Let me know if this works ... View more

Pat,   The log file you provided gives some insight into the problem, but we'll need some additional details.  To capture verbose details on the installation process, please do the following: Enable windows installer logging by creating a registry key. Use this doc to add the key: http://support.microsoft.com/kb/223300 Once enabled, start the Silverlight/WPF install and step through it until it fails. Go the %TEMP% folder (e.g. C:\Users\<username>\AppData\Local\Temp).   You should see a newly created .LOG file.   Attach this file to your next forum post.  Optional.  You may want to remove the key added in step 1.

Unfortunately we've been unable to reproduce the problems mentioned in this forum thread regarding the ArcGIS SharePoint 1.1.1 product on SharePoint 2010.  On that note, ESRI will release version 2.0 of the ArcGIS SharePoint product for SharePoint 2010 in late September.   All active development for the SharePoint 2010 platform is going into the 2.0 product.   We do have a limited beta program for ArcGIS SharePoint 2.0.  Let me know if you would like to participate.        Thanks -Rex Hansen Esri | Product Lead, ArcGIS SharePoint rhansen@esri.com ...

Here are a few follow-up questions: 1) Under Control Panel > Programs and Features do you see any program named "ArcGIS API for Microsoft Silverlight/WPF..."? 2) Have you installed a 2.0 beta version of the ArcGIS Silverlight/WPF API?  3) Where does the installation fail?  Do you get an error message?  If so, what is the error? 4) What is the size of the setup you downloaded from the ArcGIS resource center?  For example, for ArcGIS Silverlight/WPF v2.0, what is the size of the ArcGISSilverlightWPF20.exe you downloaded? Thanks ... View more

In general, the first layer in the map's layers collection will set the map's spatial reference.  If the spatial reference of a tiled map service layer does not match the spatial reference of the map, it will not display.   Bing Maps tiled map services host map data in the Web Mercator projection which is represented as a spatial reference with a well-known ID (WKID) of 102113.   If the Bing Maps layer is first, the USGS Topographic layer (if a tiled map service) must have a spatial reference that matches a WKID for Web Mercator (102113,102100,3857).   If it does not, it will not display.   The reverse also applies (USGS layer first, Bing second). ...

This behavior usually indicates something changed in the data source.  Just to clarify your statement "The layer displays fine as points on the map, the spatial reference appears to be correct, and when debugging, we can see that the graphics layer is being populated with the data. It just does not display."   So just to confirm, does the XY event layer display successfully as points using marker symbols when clustering is not applied? Have you tried using the default clusterer?  Does it work? Are you reprojecting the coordinates before display on the map?  For your custom clusterer, are you using the sample code referenced here? http://resources.esri.com/help/9.3/arcgisserver/apis/silverlight/samples/start.htm#CustomClusterer ...

There are a number of resources available online to assist you with consuming geoprocessing services: Concepts: http://help.arcgis.com/en/webapi/silverlight/help?GP_task.htm OMD (in Tasks section): http://help.arcgis.com/en/webapi/silverlight/help/ArcGISSilverlightOMDs.pdf Interactive samples (links to first sample in a section of geoprocessing samples): http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#MessageInABottle Library Reference (link to Geoprocessor task): http://help.arcgis.com/en/webapi/silverlight/apiref/api_start.htm?ESRI.ArcGIS.Client~ESRI.ArcGIS.Client.Tasks.Geoprocessor.html The GP* types used by the task are in the same namespace as the task (ESRI.ArcGIS.Client.Tasks).  On a side note, the data for the geoprocessing service demonstrated in the Clip Features sample mentioned in the post by dbroux above (http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#ClipFeatures) is available with ArcGIS Server 10 SDK.  Here is the .NET ADF sample that references the data: http://help.arcgis.com/en/sdk/10.0/serveradf_net/conceptualhelp/index.html#/ArcGIS_ClipShip_Geoprocessing/00020000013r000000/ Hope this helps ...

Hi folks,    Unfortunately some Resource Center downloads exhibited problems at the end of July and beginning of August. Please download the 2.0 Silverlight/WPF API setup again and run through the installation.   If you continue to experience a problem please provide me with the following: 1) Size of the download. 2) The browser used to download the setup.  Include the version of the browser. 3) Operating system on which the browser is running.  Thanks ...

No.  The ArcGIS Silverlight API is designed to work with ArcGIS Server services via REST, which was first introduced with ArcGIS Server 9.3.   To use SOAP services (ArcGIS Server and otherwise) in Silverlight, you need to generate the client side proxies.  The .NET SDK and Silverlight SDK include a SOAP toolkit to generate the proxies for you.  New in Silverlight 3 (and available in 4) is the SlSvcUtil command line utility to generate SOAP proxies for the Silverlight platform.  You'll find the utility in %Program Files%\Microsoft SDKs\Silverlight\v4.0\Tools.   You can download the wsdls for ArcGIS Server 10 services here: http://help.arcgis.com/EN/arcgisserver/10.0/apis/soap/Pre-generated_proxies.htm Once you have the wsdls, you can use SlSvcUtil.exe to generate a single class that contains all the proxies and value object types: SlSvcUtil.exe *.wsdl /language:CS /namespace:"*,ESRI.ArcGIS.SOAP.Silverlight" /out:ESRI.ArcGIS.SOAP.Silverlight.cs Note the parameter "*.wsdl" which indicates that all wsdl files in the current directory will be processed.  You will see a series of errors indicating that numerous types have already been declared.  This is expected since the same types are defined in multiple wsdls - you can ignore the error.  At this point you can use VS2010 or csc.exe to build a Silverlight library from the cs file.  You can download an example Silverlight-ArcGIS Server SOAP app here: http://rexhansen.com/2009/01/consuming-arcgis-server-soap-services.html   It's an old post, but the code still applies. Note, ArcGIS Server SOAP XML is designed for public use.  SOAP Binary is only designed for ArcObjects clients (e.g. ArcMap). ... View more

The Interactive SDK download has been updated to include the SyntaxHighlighting.dll.   You will need to unblock the assembly before building and running and the application.  Here's a link on how to do this:  http://go.microsoft.com/fwlink/?LinkId=179545 ... View more

During initialization a FeatureLayer will send two requests.  One for metadata and another to query and return features.   If using a proxy and defining the ProxyUrl property, both requests will be redirected through the proxy.   There are two issues I discovered with the proxy page download included with the SDK: 1) The proxy.config file is not found when located outside the root folder.  To fix, adjust the following method:     public static string GetFilename(HttpContext context)     {         return context.Server.MapPath("proxy.config");     } 2) If not token secured, the proxy always checks for Windows\HTTP authentication, which results in a duplication of requests. Both items have been fixed in the SDK download from this page: http://help.arcgis.com/en/webapi/silverlight/help?Secure_services.htm ... View more
