When trying to use the TravelItineraryReadService 3.8.0 service via VB i get the following error just by doing
Private service As TravelItineraryReadService
service = New TravelItineraryReadService
the error output:

i am using visual studio 2015,
added the WSDL as
it doesn't matter if i add the header info or not. it always fails.
This is due to response object issue in generated web service proxy class.
Changed the following and works well for me.
1.
Private associatedDataField()() As TravelItineraryReadRSTravelItineraryItineraryInfoItineraryPricingPriceQuoteMiscInformationTicketingFeesFeeInformationAssociatedDataAssociatedDataItem
----change as below-- Private associatedDataField() As
TravelItineraryReadRSTravelItineraryItineraryInfoItineraryPricingPriceQuoteMiscInformationTicketingFeesFeeInformationAssociatedDataAssociatedDataItem
Public Property AssociatedData() As TravelItineraryReadRSTravelItineraryItineraryInfoItineraryPricingPriceQuoteMiscInformationTicketingFeesFeeInformationAssociatedDataAssociatedDataItem()()
----change as below--
Public Property AssociatedData() As TravelItineraryReadRSTravelItineraryItineraryInfoItineraryPricingPriceQuoteMiscInformationTicketingFeesFeeInformationAssociatedDataAssociatedDataItem()

Public Overridable Property Diagnosis As DbSet(Of Diagnosis)
in the DBContext.vb.
Then in the package manager console, i entered Add-Migration Diagnosis. But below error comes out. Why is this? Can anyone help me out please?

I don't know if this is relevant or not, but in my web.config, there is a Default Connection that is already pre-set when i first created my project. When i first did Enable-Migrations i had to specify which connection it was. I've removed that line but it still doesn't work.
Previously when i did the add-migration, it didn't work because i simply created a class and added declaration of the respective strings, integer, etc. as variables like this:
Public Property id As String
Now it suddenly popped into my mind that i had to give a more elaborate description on each of the variables such as below:
<Key>
<StringLength(20)>
Public Property id As String
Now it works =')
I am trying to call .Net method from my ESB Mule project.
I created the following class in VS 2013:
namespace NicePerform.ESBDataResolver
{
public class DataResolver
{
public Object InitInfrastructure(string sysAdminURL, string delimiter, int refreshIntervalInMin)
{
/// do something
}
}
}
In the Mule project I configured DotNet connector.
<dotnet:config name="DotNet_Connector" assemblyType="NicePerform.ESBDataResolver.DataResolver, NicePerform.ESBDataResolver" assemblyPath="D:\tfs\NGA\Splash\ESB\Debug\NicePerform.ESBDataResolver.dll" scope="Singleton" doc:name="DotNet Connector"/>
<dotnet:execute config-ref="DotNet_Connector" methodName="InitInfrastructure(System.String sysAdminURL, System.String delimiter, System.Int32 refreshIntervalInMin)" doc:name="DotNet Connector"/>
I am filling the payload:
{"sysAdminURL":"${sysAdmin}","delimiter":"${delimiter}","refreshIntervalInMin":"${userAdminRefreshInterval}"}
But on call .net method I am failing with the following exception:
System.Exception: Error looking for method named InitInfrastructure(System.String sysAdminURL, System.String delimiter, System.Int32 refreshIntervalInMin) : The method name InitInfrastructure(System.String sysAdminURL, System.String delimiter, System.Int32 refreshIntervalInMin) doesn't exist

I try to set namespace together with method name with no success. If I am changing calling method signature to receive single string parameter - it works. What I am doing wrong?
Everything looks correct to me, but I dont have examplecode setup for it.
You mention that you have tested with setting the namespace with the method name. have you also tested the Classname together with the method name or both?
In C# int is equal to System.Int32, and I assume this doesnt cause the issue, but it might be related.
In the example files with the connector they use a slightly different notation for the methodName field: . Since we cant find an issue in your code, you could just as well try a few other ways of calling it.
I have simple WiX (Microsoft.Deployment.WindowsInstaller) custom action:
[CustomAction]
public static ActionResult TestDtf(Session session)
{
MessageBox.Show("Test");
ActionResult result = ActionResult.Success;
return result;
}
I need to have a deferred / system context custom action I created using InstallShield call this, so how do I set up the Method Signature arguments so that it sends the Session? Is 'Session' basically the Msi handle? I have tried using the 'MsiHandle' value, however this results in error:
InstallShield: Deferred action requested property MsiHiddenProperties not provided by CustomActionData
InstallShield: Loading assembly Test.Installation.CustomActions from resource 4098
InstallShield: Loading Assembly Microsoft.Deployment.WindowsInstaller

You don't as you don't need to. You are creating the wrong kind of custom action in InstallShield. Pretend your DLL isn't .NET because as far as DTF is concerned, it's not. It has been encapsulated as a native DLL.
The answer for this problem for me was to change the type of DLL CA I was adding to an MSI DLL. Then it only asks for the function name and not parameters and return values. I could not find this readily explained online unfortunately and it took a bit of guessing. Here is what your method signature should look like.
[CustomAction]
public static ActionResult VerifyCA( Session session )
{
//Record record = new Record( 2 );
//record[0] = "[1]";
//record[1] = "Testing Wix message";
//session.Message( InstallMessage.Error, record );
return ActionResult.Failure;
}
After picking the right CA type, it works like a charm for me from Installshield 2009. Hope this helps someone.
My answer is w.r.t. Installshiled 2016 and in all likelyhood it must work the same way in earlier installshield versions as well but I've not verified the same.
Yes. The in-built MsiHandle varible is the session for the installation in progress but it requires one extra line of code to get that on C# side. I was able to achieve it in a .NET assembly which I invoke from my managed custom action. The code is as below:
//import this namespace at the top of your *.cs file
using Microsoft.Deployment.WindowsInstaller;
public static int MakeChangesInCurrentInstallSession(IntPtr hMsi)
{
Session session = Session.FromHandle(hMsi, false);
view = session.Database.OpenView("SELECT * FROM ComboBox");
view.Execute();
//do other things whatever you want to do in the installer session
//Record record = session.Database.CreateRecord(4);
//view.Modify(....);
//.....
//return success if everything went well
return (int)ActionResult.Success;
}
If you make the signature of your method like below and tried to invoke it from your managed custom action:
public static int MakeChangesInCurrentInstallSession(Session hMsi)
Then, you face the casting error as below:
InstallShield: Unexpected parameter type
Microsoft.Deployment.WindowsInstaller.Session encountered; passing
string instead
Note: For the above code to work you will have add reference to Microsoft.Deployment.WindowsInstaller.dll in your C# project from extensions tab in the add reference window. Also, since this assembly is not a part of .NET framework so you must add this assembly as a dependency in your managed custom action of Installshield execute sequence as detailed here.
I am tying to get the generic List of user List<User> object from my web service to my web application. probably this is common issue. i searched a lot but got different remedies with each link. so finally i decide to ask to chaps over here... anyways
I am using console application for fetching the data from my hosted wcf web service. where as my WCf web service having the Entity framework 4.1. am using objects from its model class. when i tried to add service reference to my web application , it typically generates the proxy in web app. i am able to post data means i could create user. but while getusers which is returning List , getting following exceptions...:

http://myserver/AdminService/MyAdminService.svc. This could be due to
the service endpoint binding not using the HTTP protocol. This could
also be due to an HTTP request context being aborted by the server

details.

What should be this issue. me and team searching for this since 3 days. but unfortunately not overcome so far...
I tried lot of stuffs like add serializable attribute, endpoint modifications ... i can not recollect all :) ... probably you may give us right directions...
The reason is that EF classes are by default proxied at runtime to support lazy loading and dynamic change tracking. So you don't serialize User class but class derived from User at runtime. WCF doesn't like that. Turn off proxy creation on your context.
context.Configuration.ProxyCreationEnabled = false;
I have created service to get the country details information of various clients, but while hosting the service I am getting this exception. I am using basic http binding.

I have businessobject[datamember] in another project. I have referred its dll here.
You can view my class
using System;

using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
using Pariwaar.BusinessObject;
using Pariwaar.DataAccessLayer;

// NOTE: If you change the class name "ReferenceDataService" here, you must also update the reference to "ReferenceDataService" in Web.config.
public class ReferenceDataService : IReferenceDataService

{ return objDAL.GetState(CountryId); }
public List<CityBO> GetCity(int StateId)
{ return objDAL.GetCity(StateId); }
}
}
Why is this working fine with another WCF service, but giving me an error with another service?
Well, the error is pretty clear:
System.Runtime.Serialization.InvalidDataContractException:
Type
'Pariwaar.BusinessObject.CountryBO'
cannot be serialized. Consider marking
it with the DataContractAttribute
attribute, and marking all of its
members you want serialized with the
DataMemberAttribute attribute. See
the Microsoft .NET Framework
documentation for other supported
types.
You're obviously using a datatype Pariwaar.BusinessObject.CountryBO as parameter or return value for one of your WCF service methods, but that class doesn't have a [DataContract] attribute on it.
See the MSDN docs on Using Data Contracts to learn about data contracts and how to make your objects useable by WCF. See this blog post - WCF Basics: Data Contracts for another view on the same topic.
All complex types (e.g. class) should be marked with [DataContract], all fields that you want to include in your WCF messages with [DataMember]:
[DataContract]
class Pariwaar.BusinessObject.CountryBO
{
[DataMember]
string CountryName { get; set; }
[DataMember]
string CountryCurrency { get; set; }
[DataMember]
string CountryISOCode { get; set; }
........
}

Hi I encountered the same problem, It was because there was no default constructor on the object CountryBO.
This error may occur in case of by mistake we have used a type which is not kept contract and might have been used in a List<> or public variable of another DataContract
