I just installed MVC 5 futures in my solution using Package Manager, but I cannot find this helper method Html.Serialize, which was there in previous MVC Futures releases.
My Question: What namespace I need to include to start using Html.Serialize helper method with MVC 5 Futures?
Apparently, this extension helper is no longer included in the current MVC Futures.
In my case, I replaced the function call Html.Serialize by MvcSerializer.Serialize method which is included in Microsoft.Web.Mvc namespace.
To serialize any object in a hidden field:
#Html.Hidden("otherComplexData", new Microsoft.Web.Mvc.MvcSerializer().Serialize(complexObject))
Later, the controller can turn back the initial object:
[HttpPost]
public ActionResult Index(
IndexViewModel model,
[Deserialize] DataType otherComplexData
)
I hope you find it useful.

We have just upgraded from Automapper 4 to Automapper 10 (I have also repeated the same problem on Automapper 8.1.1)
I am unable to initialise the Automapper. T is a Profile class with CreateMap calls.
var configuration = new MapperConfiguration(cfg =>
{
cfg.AddProfile<T>();
});
After cfg.AddProfile it disappears into endless loops and never returns. It consumes 2GB of Memory before I pull the pin (this takes a few minutes). I've debugged into AutoMapper (this is from 8.1.1) and inside MapperConfiguration it calls a method Seal(); This is where it goes into loops.
The Profile class has 1200 calls to CreateMap
Any suggestions? Automapper 4 worked well, except for a few cases where it would randomly return a null reference exception trying to find a map.
This is .Net Framework 4.7.2 and Automapper 8.1.1 (and also with Automapper 10).
I have code using AutoMapper 3.2.1.0 that uses the method ToNullSafeString().
I upgraded the NUGet package to 4.1.1.0, and I can no longer find the method in their package.Does anyone know the recommended approach to replacing the function? Is there a new construct that is functionally equivalent? If so, I cannot figure what it is. Nor can I find any mention of why it was removed.
This question has actually been answered pretty well in a couple of comments below it. For completeness, here are a couple of actual implementations of solutions.
Short answer
Probably both the simplest and the best solution: Replace all instances of .ToNullSafeString() with ?.ToString(). This does the same, but uses functionality built into newer versions of .Net instead of relying on an external extension method.
Alternative answer
If you've got a bunch of calls to the ToNullSafeString() method from the earlier version Automapper, and for some reason or other you can't or don't want to go through all your code and edit it away right now, you can use this instead.
Add the following class to your project, and make sure it can be reached from any classes that previously called the Automapper-method. Those calls will then automatically point to this instead.
public static class NullSafeStringHelper
{
public static string ToNullSafeString(this object value)
{
return value?.ToString();
}
}
I'm in the process of trying to migrate a R# extension project from R# 6 to R# 8. (I've taken over a project that someone wrote, and I'm new to writing extensions.)
In the existing v6 project there is a class that derives from RenameWorkflow, and the constructor used to look like this;
public class RenameStepWorkflow : RenameWorkflow
{
public RenameStepWorkflow(ISolution Solution, string ActionId)
: base(Solution, ActionId)
{
}
This used to work in R# SDK v 6, but now in V8, RenameWorkflow no longer has a constructor that takes Solution and actionId. The new constructor signature now looks like this;
public RenameWorkflow(
IShellLocks locks,
SearchDomainFactory searchDomainFactory,
RenameRefactoringService renameRefactoringService,
ISolution solution,
string actionId);
now heres my problem that I need help with (I think)
I've copied the constructor, and now the constructor of this class has to satisfy these new dependancies. Through some digging I've managed to find a way to satisfy all the dependencies, except for 'SearchDomainFactory'. The closest I can come to instantiating via the updated constructor is as follows;
new RenameStepWorkflow(Solution.Locks, JetBrains.ReSharper.Psi.Search.SearchDomainFactory.Instance, RenameRefactoringService.Instance, this.Solution, null)
All looks good, except that JetBrains.ReSharper.Psi.Search.SearchDomainFactory.Instance is marked as Obsolete, and gives me a compile error that I cannot work around, even using #pragma does not allow me to compile the code. The exact error message I get when I compile is Error 16 'JetBrains.ReSharper.Psi.Search.SearchDomainFactory.Instance' is obsolete: 'Inject me!'
Obvious next question..ok, how? How do I 'inject you'? I cannot find any documentation over this new breaking change, in fact, I cannot find any documentation (or sample projects) that even mentions DrivenRefactoringWorkflow or RenameWorkflow, (the classes that now require the new SearchDomainFactory), or any information on SearchDomainFactory.Instance suddenly now obsolete and how to satisfy the need to 'inject' it.
Any help would be most appreciated! Thank you,

ReSharper has its own IoC container, which is responsible for creating instances of classes, and "injecting" dependencies as constructor parameters. Classes marked with attributes such as [ShellComponent] or [SolutionComponent] are handled by the container, created when the application starts or a solution is loaded, respectively.
Dependencies should be injected as constructor parameters, rather than using methods like GetComponent<TDependency> or static Instance properties, as this allows the container to control dependency lifetime, and ensure you're depending on appropriate components, and not creating leaks - a shell component cannot depend on a solution component for instance, it won't exist when the shell component is being created.
ReSharper introduced the IoC container a few releases ago, and a large proportion of the codebase has been updated to use it correctly, but there are a few hold-outs, where things are still done in a less than ideal manner - static Instance properties and calls to GetComponent. This is what you've encountered. You should be able to get an instance of SearchDomainFactory by putting it as a constructor parameter in your component.
You can find out more about the Component Model (the IoC container and related functionality) in the devguide: https://www.jetbrains.com/resharper/devguide/Platform/ComponentModel.html
I am using the very excellent servicestack libaries and trying to generate a ASP.NET web-service reference (old style not WCF) from within VS2010 across my servicestack WSDL - Soap11. To nicely wrap the service WSDL.
The DTO's are in a seperate assembly/namespace (My.WS.DTO) from the AppHost/services and are following the request/response naming convention.. when I try to generate the reference through visual studio I get the following error in VS.
Custom tool error: Unable to import WebService/Schema. Unable to import binding 'BasicHttpBinding_ISyncReply' from namespace 'http://schemas.servicestack.net/types'. Unable to import operation 'GetMyDetails'. The element 'http://schemas.servicestack.net/types:GetMyDetails' is missing.
NOTE: GetMyDetails is just the first service that appears in the list - so I dont believe this is the problem.
I have tried adding the assembly namespace in the AppHost file using
EndpointHostConfig.Instance.WsdlServiceNamespace = "My.WS.DTO"; and this just causes the same generation error (as above) but with 'My.WS.DTO' instead of 'http://schemas.servicestack.net/types'.
I assume it is perhaps some sort of referencing problem but any guidance as to what I might be doing wrong would be great.
cheers
I don't know if this is still an issue for you but I had a similar problem and found that I had not decorated one of my DTOs with [DataContract] and [DataMember] attributes, as described on the SOAP Support wiki page. Once you have added these to your DTO it will be declared in the type section of the WSDL.
Have a look at using [DataContract (Namespace = "YOUR NAMESPACE")] on top of your DTO's. This is how my objects are referenced.
[DataContract(Namespace = "My.WS.DTO")]
public class Account{
}
I also use this in my service model. [System.ServiceModel.ServiceContract()] and [System.ServiceModel.OperationContract()]
[System.ServiceModel.ServiceContract()]
public class SendGetAccountResponseService : IService<SendGetAccountNotification>
{
#region IService implementation
[System.ServiceModel.OperationContract()]
public object Execute (SendGetAccountNotification request)
{
Console.WriteLine ("Reached");
return null;
}
#endregion
}
Hope this helps / solves your problem.
I know this is an old question, but I had to add SOAP support for a 3rd party that refused to support REST very recently to my ServiceStack implementation so it could still be relevant to other people still having this issue.
I had the same issue you were having:
Unable to import binding 'BasicHttpBinding_ISyncReply'...
And like mickfold previously answered I needed to add [DataContract] and [DataMember] to my class definitions and their properties.
But I also had to add the following to my AssemblyInfo.cs file before the error went away for me:
[assembly: ContractNamespace("http://schemas.servicestack.net/types", ClrNamespace = "My Type Namespace")]
I assume that you will need one of these lines for every single namespace where you have a type declared, which based upon the original question above would be My.WS.DTO.
Is it possible to use ASP.NET Dynamic Data with SubSonic 3 in-place of Linq to SQL classes or the Entity Framework? MetaModel.RegisterContext() throws an exception if you use the context class that SubSonic generates. I thought I remembered coming across a SubSonic/Dynamic Data example back before SubSonic 3 was released but I can't find it now. Has anyone been able to get this to work?
I just got Subsonic 3.0.0.4 ActiveRecord working last night in Visual Studio 2010 with my SQLite database after a little bit of work and I've tried to document the steps taken here for your benefit.
Start by adding a New Item -> WCF Data Service to the project you're using to host your webapp/webservices then modify it similar to my PinsDataService.svc.cs below:
public class PinsDataService : DataService<PINS.Lib.dbPINSDB>
{
// This method is called only once to initialize service-wide policies.
public static void InitializeService(DataServiceConfiguration config)
{
config.SetEntitySetAccessRule("*", EntitySetRights.All);
config.UseVerboseErrors = true;
config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2;
}
}
At this point your Dynamic Data Service would probably be working if you matched all the database naming conventions perfectly but I didn't have that kind of luck. In my ActiveRecord.tt template I had to prepend the following two lines before the public partial class declarations:
[DataServiceKey("<#=tbl.PrimaryKey #>")]
[IgnoreProperties("Columns")]
public partial class <#=tbl.ClassName#>: IActiveRecord {
I then added references to System.Data and System.Data.Services.Client followed by the inclusion of using statements for using System.Data.Services and using System.Data.Services.Common at the top of the ActiveRecord.tt template.
The next step was to use the IUpdateable partial class implementation from this blog post http://blogs.msdn.com/aconrad/archive/2008/12/05/developing-an-astoria-data-provider-for-subsonic.aspx and change the public partial class dbPINSDB : IUpdatable to match my subsonic DatabaseName declared in Settings.ttinclude
Then to consume the data in a separate client app/library I started by adding a 'Service Reference' named PinsDataService to the PinsDataService.svc from my client app and went to town:
PinsDataService.dbPINSDB PinsDb =
new PinsDataService.dbPINSDB(new Uri("http://localhost:1918/PinsDataService.svc/"));
PinsDataService.Alarm activeAlarm =
PinsDb.Alarms.Where(i => i.ID == myAA.Alarm_ID).Take(1).ElementAt(0);
Note how I'm doing a Where query that returns only 1 object but I threw in the Take(1) and then ElementAt(0) because I kept getting errors when I tried to use SingleOrDefault() or First()
Hope this helps--also, I'm already aware that dbPINSDB is a really bad name for my Subsonic Database ;)
