I came across with this situation. I have one already developed Application in 2.0, Now in this application i want to use one WCF Service that is developed in 4.0. How can i do this?
I tried the following
1. Regular Method Add the Service Reference and then use that. It didn't work for me.
2. I googled it and i got one more method, using svcutil.exe, but i dont have svcutil.exe with 2.0.
Waiting for the response.
Thanks in advance.
Windows Communication Foundation (WCF) was first introduced to the .NET Framework as part of .NET 3.0. It's not available with .NET 2.0.
If the WCF service exposes a SOAP endpoint then you may be able to use it through the Web Service Extensions (WSE) that were published for old versions of Visual Studio. See here: http://www.microsoft.com/download/en/details.aspx?id=10854 for details.
If you want to use a service written in .Net 4 with a .Net 2.0 project, you should be able to use basic http binding. That should allow it to interop with a client that knows nothing about WCF. It's similar to using an old school .asmx web service.

As I know DevForce use WCF for the communications between client and server.
But in newer version of .NET (Core 3.1, .NET5, .NET6 etc) WCF services not supported.
Is it possible to configure DevForce to use endpoints based on GRPC\WebApi instead of WCF?
As a trend for the future, you can try using gRPC, CoreWCF, and ASP.NET Core MVC instead of WCF. With the.NET upgrade, some technologies have been fully ported, but not WCF, and the replacement for WCF is the technology mentioned above.
The following article lists some of their characteristics for your reference, I hope it can help you.
I've created a custom WCF Rest web service in a sharepoint site which uses .net 3.5 only not 4
, I found that Question , marc_s talked about REST Starter Kit but I found that it's no longer supported .
Any ideas about how to implement caching in this situation ?
Thanks.
System.Web.Caching.Cache is your friend. For Framework 4.0 or higher use the MemoryCache or the ObjectCache.
Don't forget about Microsoft Enterprise Library Caching Application Block
I have developed a WCF service (framework 4.0) which should communicate with a client through BasicHttpBinding.
I have kept my (data)contracts in a separate assembly cause I want them to be reused by multiple clients.
Everything works as expected if I reference my WCF Service as a service (Service References) in a .net 4 client and set "Reuse types in referenced assemblies".
The problem is I have to consume the same WCF service with a .net 2 client.
In this situation the generated proxy is different from my shared assembly datacontract and I don't seem to be able to reuse it or cast it to the generated proxy.
Is there a way to solve this issue?
Thanks for your help.
Well, .NET 2.0 has no WCF API at all because it wasn't added until 3.0. So forget sharing the library because there's nothing to really share it with. The .NET 2.0 application will have to use the older WSE (Web Service Extensions) API. Documentation on WSE is available here on MSDN and you can download the last version of the WSE API that was made, 3.0 SP3, here.
You should have no problem getting WSE to talk to WCF via a basicHttpBinding. Things would only get complicated if you started using WS-* stuff and, even then, WSE supports a lot of that. It's just hard to find help on it since it's a deprecated API.
Im using WCF REST 4.0 meaning to say their is no .svc file.. So I have 3 different service classes in one service WCF Rest Application project. And I registered all these services in the Global.asax
What im trying to do is that I have a set of Business Functions from a lower framework e.g: .NET 1.0/2.0 where in i use datasets and not call basic add/update/delete entity function unlike in the newer releases. So I wanted to ask if this type of match would work in .Net 4.0 or is their any other reason for this?
Thank you
If your services work in Web Development server than they have to work in IIS. What version of IIS do you use? Remember that extensionless URLs are only supported in IIS 7.x. If you want to use them in older version you have to modify IIS configuration (check this thread). Also make sure that your IIS has properly registred .NET 4.0 and all realted ISAPI. If you installed .NET 4.0 after IIS it is best to use aspnet_regiis.exe from .NET 4.0 folder.
I am facing a problem.
Please explain if this is possible or not.
1) I created a Service Library (.Net 3.5)
2) I created a Windows Service (.Net 3.5), added ServiceHost and implemented my ServiceLibrary to work as a TCP Endpoint.
3) Next I created a Console Client (.Net 3.5) and tried to get data from my TCP Endpoint…(svcutil….proxy.cs generation). Worked absolutely fine.
4) I have a Windows Client(.Net 1.1). How do I configure it to use this new Service? I can't add Proxy.cs as it says that servicemodel cannot be found…
You will need to use a basicHttpBinding, which is backward compatible and can be consumed by a .net 1.1 client. You should be able to find plenty of useful examples on the web: Consuming WCF with .Net 1.1 Basic Binding. For example, this Link describes that binding and usage of Soap 1.1 to make it compatible with .Net 1.1.
For more details on different scenarios and the range of wcf configuration possibilities, try exploring this CodePlex Link, specifically the Application Scenarios section that provides details of different setups. I believe that you will require a basicHttpBinding rather than a netTcpBinding in order to work with legacy protocols. The netTCPBinding would assume that you have .NET 3.0 at both ends. See this MSDN Bindings Link.
