New Post: Object reference not set to an instance

I think it would help to see the signatures of the problem calls, including any types referenced if possible.

Hi Rob,

Thanks a lot for the reply. Actually in this case all the endpoints are using NetTcpBinding. We have all the enpoint listed in the client configuration file with the binding configuration and behavior configuration in it. I am able to see all the call details and their response in the message log file. Even I am getting the call details for the 2 calls which are not getting generated. I have only one proxy assembly(dll) which is having all the proxies. When I am creating C# script by providing this assembly, it generates code for other calls and adding this dll under the reference node of the solution. I am able to create the proxy client for the particular service by hand and through the proxy client I am able to see the call which is not getting generated by the tool. From the log I am able to see that a lot of things are passed to this call. So creating this call by hand would be very difficult.

The call looks like below one.

Can you give me some details about the calls that are failing?

Thanks

Rob

Hi,
I am using WCF Loadtest for generating the code from the WCF message log file. But the problem is if I select all the calls captured and then provide the proxy assembly, it does not generate the code.
It gives error like "Object reference not set to an instance". But if I take out 2 calls from the list of calls by unchecking the checkboxes beside it, then provide the same proxy assembly. It generates the code. The code also works fine. But we need to generate the left out calls as well.
How can we do that? Can anybody help in this case?

This appears to be because the assemblies are for .NET 4.0. I have started the process of updating the tool to work with .NET 4.0, not quite sure how soon I can release the update though.

Greetings,

Rob I have tried again and Now I am getting error "__The message log file did not contain any usable data. Please make sure that LogMessageAtServiceLevel and LogEntrieMessage at set.__" at code generation time. Do I need this app.config settings for Fiddler also?
I have placed ErrorImage, Fiddlerlog and dll file at https://docs.google.com/file/d/0BzWipjGotp_ueGktY09odXFLWE0/edit

(Note: VS 2010 updated your code through VS Conversion Wizard)

I added the headers on my own copy of your log file and the file parsed fine. I assume it is failing at a later stage of the process. Can you tell me what error you get? You may also need to let me have the assemblies that contain the contracts and types in order to try to repro the problem.

Regards

Rob

I tried to repro this with the Fiddler log file you provided, but it works for me. Can you check to make sure that you specified a Fiddler log file rather than WCF message log?

Regards

Rob

Sorry, I wasn't very clear, I was talking about HTTP headers, like this:

WCFLoad gives error "The message log did not contain any usable data. Please make sure that LogMessagesAtServiceLevel and LogEntireMessage are set" when try to WCFLoad code with fiddler log file.

robjarratt — Tue, 23 Apr 2013 18:19:09 GMT

I have had a look at the log file and it would seem to be because there is no SOAPAction header in the fiddler log file, which is what the parser expects to be able to find. Try adding it manually to see if that resolves your problem.

Rob

I have tried to generate code by following way
1- Fiddler2 installed.
2- Access the web (Silverlight) in IE.
3- Selected and saved the WCF requests from fiddler 2 as text file.
4- Open the VS 2010 ultimate "WCF Test" Use Pre-Captured messages log file (fiddler text) and click on Parse.

VS shows error “Not a valid message log file”
Please suggest any work around.

Check the log and image for details.

New Post: WCF load test tool support for .Net 4.5

robjarratt — Thu, 11 Apr 2013 13:13:04 GMT

I have not tried it with 4.5 so I don't know for sure. I am hoping to get some time to refresh WCF Load Test fairly soon but cannot make any promises at the moment.

New Post: WCF load test tool support for .Net 4.5

drc_cp — Tue, 09 Apr 2013 14:02:59 GMT

Hi,

There are assemblies compiled in .Net 4.5, any ideas if WCF load test tool support .Net 4.5? if not, will it supported in next build? what is time frame for next build.

There may be an incompatibility issue if we are attempting to reference a 4.5 assembly from a 4.0 unit test.

Please advise

Thanks
Ram

Yes, the service can be written in VB.NET, the client can also be written in VB.NET, it is just that the tool will only generate C#.

HI Rob,

Thanks...but can i use this tool to test a WCF service which is developed in VB.Net?
I mean my test project will be in c# but my service is developed in VB.Net. Also, the application which consumes this WCF Service are also developed in VB.Net. Is this in scope??

Thanks
