C# - Cannot Start WCF Service - "The Service Cannot Run Your Command At This Time"?
Oct 13, 2010
I've been having issues getting a service to start. I have 2 other services are identical in configuration in just about every way that start fine, but one of them refuses to start and I really need to get it to work today. I can't see any difference in their implementation or config files. I'm receiving the following messages when attempting to start the service after installing it with InstallUtil:The service is not responding to the control function more help is available by typing NET HELPMSG 2186 NET HELPMSG 2186:
Explanation: The service cannot run your command at this time
Is there any way to start another service i.e i have a one service named XYZSERVICE using this service i want to start another service i.e PQRSERVICE...
My web services have base web service method called IsGood()I want to make sure every methods in my web service call IsGood() in base web service automatically without add code in each web service method, can I do that?
I am writing a program to measure the latency(response round trip time) for a web service. I need to have this at client side.
My initial plan is to store the time at which request is sent and then calculate the difference in time when we recieve a response from the web service. Is this the correct way to measure latency of web service. This has some overhead because of storing time and all. How can this be done?
Another option is to attach a timestamp with the SOAP request. But the server should return the timestamp. This will not be possible in case of third party web services.
I've got a solution consisting of two projects: an ASP.NET Web Application project and a WCF Service Application project.
When running the solution from within the VS 2010 IDE, two browser windows are started. One browser displays the ASP.NET form page, and the other browser showing a directory listing very much like this:
Directory Listing -- /
Saturday, December 18, 2010 10:40 PM <dir> App_Data Monday, December 20, 2010 10:10 PM <dir> bin Saturday, December 18, 2010 10:53 PM 111 ChatService.svc Thursday, December 30, 2010 10:41 PM 455 ChatService.svc.cs Friday, December 31, 2010 03:27 PM <dir> DataLayer Monday, December 20, 2010 11:32 PM 265 IChatService.cs Saturday, December 18, 2010 10:40 PM <dir> obj Saturday, December 18, 2010 10:40 PM <dir> Properties Friday, December 31, 2010 03:33 PM 4,609 Services.csproj Friday, December 31, 2010 03:33 PM 1,086 Services.csproj.user Sunday, December 19, 2010 08:35 AM 58 Services.Publish.xml Monday, December 20, 2010 02:09 PM 959 Web.config Saturday, December 18, 2010 10:40 PM 247 Web.Debug.config Saturday, December 18, 2010 10:40 PM 343 Web.Release.config
Version Information: ASP.NET Development Server 10.0.0.0
The second browser window (with the directory listing) is obviously the WCF service. Now, is there a way to suppress the WCF service browser window, or is this the expected behavior since the WCF Service Application project is self-hosted?
Also, I've got the solution properties set to multiple startup projects.
There is a Web Service installed on Amazon Server. Exposed WebMethod should start an executable. But, it seems that process (executable) started by WebMethod has not permissions to finish its job. If a WebMethod is called locally (using IE on Amazon VM) I can trace some events into log file placed on the path: C:\LogFiles. But, if it is called from remote machine, there is no even log files. Locally, on my machine all works fine.The question: is there any way or settings in IIS7 to allow to my WebService to create process that can do everything I want to do? In web.config file I added a line:
<identity impersonate="true" userName="USERNAME" password="password"/> (userName and password are, of course, written correctly in the file).
Also, I tried to use impersonization as it is explained here, but there is no result. My process can't do its job, it cannot even trace actions into log file. Locally, on my machine, everything works fine. how to change settings or whatever into IIS7?
EDIT: In addition to the main question: my WebService is not able even to create log files on the path: C:\LogFiles - although it is able if it started locally, but remotely there is no simple log file that contains some string. How to allow it to create simple text files?
I am trying to run a sample WCF ADO.Net Data Sertice on my IIS, which give me message The resource cannot be found. Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly. Requested URL: /testing_wcf_service/WcfDataService1.svc/Web Config File as
At work I need to create a new web application, that will connect to an MySql Database.
(So far I only have expercience with Linq-To-Sql classes and MSSQL servers.)
My superior tells me to use the entity framework (he probably refers to Linq-To-Entity) and provide everything as a service based architecture. Unfortunately nobody at work has experience with that framework nor with a real nice server oriented architecture. This speficic project I'm leading will be long-term, meaning multiple years, so it would be best to design it the way, that multiple target plattforms like asp.net, c# wpf, ... could use it)For now, the main target plattform is ASP.net
So I do have the following questions:
1) Where can I read best what's really behind service oriented architecture (but for now beginner tutorials work fine as well) and how to use it in best practise?
2) So far I can't see a real difference between Linq-To-Sql classes and the information I've googled so far on the 'entity framework'. So, whats the difference? Where do I find nice tutorials for it?
3) Is there any difference in the entity framework regarding the database server (MSSQL or MySQL)? If not, does that mean that code snipperts I will stumble across will word database independent?
I have built a WCF Service that is being consumed by a Silverlight app. At first I created one method that was very simple:
public String SfTest() { return "SF Test"; }
No poblem. My silverlight app references my service and displays "SF Test" in a textbox. Now I add a method to my wcf service like this:
public List<String> GetTest() { List<String> list = new List<string>(); String a = "a"; list.Add(a); String b = "b"; list.Add(b); return list; }
I update the reference to the service in my Silverlight app and the using statement in my xaml cs page throws an error like the service doesn't even exist although it is there. I am assuming the problem has to do with datatypes or serialization or something like that but it is driving me up the wall. Why can't I consume a simple generic list in my Silverlight app through the WCF service.
I developed a web service in VS2010 on my local machine, wrote a consumer of it also locally, and that all works.
I copied the dll and the asmx file to our server, and I am getting an error when I try to invoke it from a browser (also still on the server machine) to make sure it correctly exposes its web methods, but it is not, it is saying "Could not create type 'Service'". That error comes from this line:
Line 1: <%@ WebService Language="C#" CodeBehind="~/App_Code/WarrantyDuplicate.cs" Class="Service" %> There other web services in the same folder on the server that all work fine so I don't believe it's an IIS setup thing.
This is my first web service in C# and when I created it in VS I did think it odd that the code behind file went into App_Code (as you can see from the line in the asmx file) and is just named dot-cs rather than asmx-dot-cs. But since it worked fine locally, I wasn't sure that mattered.
I have asp.net 2.0 site which is calling web services hosted on another server. When i have an xml file from where web service ip for eg. www.mysite/webservice1/myservice.asmx is given. When i call the same server from developer machine using local networkit works fine.But the same is when hosted remotely and from client end when services is called reading xml fiile from client machine it given a message 'remote server not connecting'.
I am not sure which approach I should use. I have a web application that needs to get/receive data from a third party application that is in a secure remote network. The data needs to be secure during transport. The data layers cannot be exposed and the databases will not talk to each other. The data will be received from remote application on demand, or will get at scheduled intervals.
I have looked at WCF, but not sure if this will work. Can a WCF service be used to receive data as needed from a remote sender or service? Is this a secure way of doing it? I have also looked at SFTP using some XML/XSLT, but I don't think this is the right way to go. In addition, some data may be transported from my web application to the remote application (mostly reports at first). What protocols are used to transfer data between HIPAA compliant applications?
I am writing two ASP.NET apps. One is a web service that provides xml data and the other is a web client that will use the service to display and manipulate data. I would like for the web service to do the membership authentication and authorization. Is there any way to simply point the login controls in my client application to the web service instead of to a database. I assume I would have to provide the necesarry methods in my web service interface, which would then use the membership provider database I created and pass the results back through to the client.
Is this possible? I have seen many articles on security provisioin from a web service but none has really been what I am looking for. I was hoping that, since my service and my client are both written in ASP.NET, there might be some built functionality that would benefit me.
I'm currently trying to work out the best way to build this web application, which will then be intergrated on other systems, such as WinForms, Intranets etc.
We hope to include the usual layers i.e. DAL, BLL, BOL and UI but I have been experimenting with Entity Framework 4 and WCF Data Services and managed to get something in place where I was using WCF as a gateway to EF4.
i.e. Adding a Service Reference to my project and then using the EF4 context and writing LINQ queries against the DB
e.g.[Code]....
Now with the current setup I would still need to write a DAL Class Library, that interacts with the Data Service, because as I said WCF Data Services only seems to be a gateway, I can't see where to put the code (above) in the Data Service and then how I could these methods.
My questions are: 1. How do I develop a WCF Data Service in such a way to allow this behaviour - I know how I could do it using ASMX web service, something like [Code]....
2. If I am to use WCF Data Services, how is serialization handled (if at all) - again I know how to do something in ASMX web services
3. Again, If I am to use WCF, how do I add Security and only allow my applications to access the web service - for obvious reasons
4. Would it be possible / logical to also include the Business Logic Layer into the web service?
Is it possible to run a web service as a particular user/service account in the same way a Windows service can?I have a service account used for connecting to the DB and want to run the webservice under this account as the users using the webservice won't have DB access.The way I see to do it is to include the Impersonate option in the Web.config file, but is there any better way to do this?
How to create an instance of web service without adding web service reference? How to identify the server address/name where the web service is hosted from C# code?
My WCF Client calls my WCF Service which then calls ASMX Web Service. The problem is i have configured my wcf client and wcf service to windows credentials type but when wcf service calls asmx service the user credentials (default windowsidentity) is not passed to asmx service.
In WCF Service i am able to get user identity by using : Thread.CurrentPrincipal.Identity.Name; WCF Service - i have disabled anonymous access and enabled windows authentication. ASMX Web Service - i have disabled anonymous access and enabled windows authentication. WCF Service Config [Code]....
<Application architecture>I'm developing ASP.NET Web Application by Visual Studio 2008.(.Net Framework Version = 2.0)I put followin two projetcs in the solution.a. Class library which implements all the buisiness logic for application. (I'll call it "ClassLib" in the followin sentence)b. ASP.NET Web applicatoin which presents UI.(I'll call it "WebApp")ClassLib uses Web Service which located on other server. So, I set web reference in it. Method for url settings for this web reference is "Dynamic".
i have created a normal web service and i want to host it outside IIS. one idea i got is to use window service as hosting environment. i have created a web service and hosted it window service and its window service is running now.would anybody please let me know that how can i call web service hosted in window service binded over soap.tcp. here is my sample code.
I have web project and class projects. one of the Class project has web reference. and i am consuming it in web project.Question: can I change class projects web reference url depending on environment DEV, Release, Test?Question: While in runtime why does not web reference's url take value from app.config?(it is taking value from Settings.settings.)
have two different applications. The only access between those two applications is Web Service.I want to delete records in the another application database by passing primary key of that table.I don't have access to database where I have to delete the records.For this, where I have to write the delete functionality.? In web service or or in my application.
