你什么时候需要调整这两个设置(下面)？这两个数字对于HttpWebRequest实例来说意味着什么？

> System.Net.ServicePointManager.DefaultConnectionLimit
> System.Net.ServicePointManager.MaxServicePointIdleTime

ServicePoint对象是否特定于域名或每个唯一的URI请求？

解决方法

这是一个很好的解释：

.net – ServicePointManager不支持* scheme的代理

我遇到了两个不同的变体：

“ServicePointManager不支持代理方案代理”
“ServicePointManager不支持HTTPS方案的代理”

当客户端尝试通过代理连接到我们的Web服务时,我收到此错误.我已经遇到这个问题与一些客户端使用代理,虽然我不知道是什么导致它.代理设置为System.Net.WebProxy和默认凭据.

使用.Net 1.1,与Microsoft.Web.Services2.

任何人都知道可能是什么原因造成的？

解决方法

好.确保代理地址以“http：//”为前缀似乎已经在我遇到的所有情况下修复了这一点.

.net – System.ServiceModel.DomainServices.EntityFramework DLL在哪里？

我正在尝试使用RIA服务,我安装了Silverlight 4和Silverlight 4 Tools / SDK,但我无法设置LINQToEntitiesDomainService,因为我找不到这个命名空间/程序集：System.ServiceModel.domainservices.EntityFramework.这个集会来自哪里,不知道为什么它会丢失？这是一个我错过的附加组件吗？

谢谢.

解决方法

你应该在： –

Program Files[ (x86)]\Microsoft SDKs\RIA Services\v1.0\Libraries\Server

正如文件夹所示,这是一个服务器端的DLL;如果您尝试添加到Silverlight项目,那么这将是问题所在.它旨在由Web项目或Web项目引用的库项目引用.
