我们使用。net Silverlight框架(version 5)开发了一个基于ArcGIS的Web应用程序，该应用程序利用ArcGIS服务器上发布的各种图层，并将其显示在地图上。用于开发web应用程序的技术:. net框架版本- 4.0 Silverlight版本- 5.1.50901.0 ESRIArcGIS。现在我们有了一个新的需求，那就是消费在Geoserver上发布的WMS层，并将这些层与ArcGIS层一起显示在同一个地图上。为了使用WMS层，我们尝试安装ESRI.ArcGIS.Client.Toolkit。数据源的插件从Nuget包管理器。它导致了以下错误。1.安装包:无法找到“ArcGISSilverlight-ToolkitDataSources”包。在行:1 char:16 + Install-Package <<<< ArcGISSilverlight-ToolkitDataSources + CategoryInfo: NotSpecified:(:) [Install-Package]， InvalidOperationException + fulllyqualifiederrorid: NuGetCmdletUnhandledException,NuGet.PowerShell.Commands。InstallPackageCommand 2。试图运行命令' Install- package ArcGISSilverlight-All -Version 3.3.0.33 '，在下面给出的链接中找到https://www.nuget.org/packages/ArcGISSilverlight-All/安装失败。回滚…… Install-Package : Could not install package 'ArcGISSilverlight-Core 3.3.0.33'.

OR Is there any alternate solution available to implement WMS layers with Silverlight in my web application? …查看更多

我们需要使用wms服务在地图中显示数据。我参考了下面给出的网站。//www.gamepadva.com/thread/69289 http://resources.arcgis.com/en/help/runtime-wpf/concepts/index.html#//017000000084000000当我尝试添加ESRI.ArcGIS.Client.Toolkit.DataSources.WmsLayer newLayer = new ESRI.ArcGIS.Client.Toolkit.DataSources.WmsLayer();在代码中，它说数据源在名称空间ESRI.ArcGIS.Client.Toolkit中不存在。我想知道“ESRI.ArcGIS.Client.Toolkit”安装在应用程序中的问题。 …查看更多
