Troubleshooting the Setup

If you cannot successfully run the SimpleClient, first check your environment settings and all other setup tasks.

Proxy Server Connection Problem

You might have a proxy connection problem.

Problem

The sample application reports that it is unable to connect to the remote server. For example:

SimpleClient.exe https://<management-server>/sdk <user> <pass>

Caught Exception : Name : WebException Message : Unable to connect to the remote server

Trace : at System.Net.HttpWebRequest.GetRequestStream() at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) at VimApi.VimService.RetrieveServiceContent(ManagedObjectReference _this) ...

Exception disconnecting.

Caught Exception : Name : NullReferenceException Message : Object reference not set to an instance of an object.

Trace: ...

Cause

Cannot connect to the Web service from Microsoft .NET client sample through the proxy server.

Solution

Try a different server on the same subnet as the client.

sgen Configuration Issues

The sgen tool used to generate XML serializer assemblies might be configured incorrectly.

Problem

The sgen tool gives unexpected results.

Cause

The behavior of the sgen tool varies depending on what you have in your Machine.config file. For example, by default sgen is supposed to output optimized non-debug code, but that is not always the case.

Solution

Adjust your sgen configuration. To get more debugging information, use the /k flag, which causes sgen to keep all its temporary generated files, including the source files and command-line option files
