I have a class library with few interfaces and the implementing classes categorized in different folders. I have generated the class diagrams of the interfaces in the project, but not able to see the relationships to the classes derived from these.
When i try to choose "Show Derived Interfaces" from the context menu of the interface, i get the below error:
Though in the same folder there are classes which are implemented from that interface.
Thanks in advance for any hint in finding the correct way.
Any hint on how to establish manual relationships between the interfaces and classes would also help. I have tried from the Toolbox -> Inheritance option, but not could not do it.
I am using Visual Studio 2022 Community Edition
Correction: I am able to create the relationships manually (from the Toolbox -> Inheritance option) between classes and its base class type.The problem i see when i try to draw the relationship from the class to its base interface.
I can reproduce your issue:
I notice your metioned:
Though in the same folder there are classes which are implemented from
that interface.
But the feature 'Show Derived Interfaces' will not pass focus to the class, but to pass focus to the interface.

I am looking at cefSharp to replace the webbrowser that comes with VS.
Where is a list of the methods and properties that is has inherent in the binaries?
You currently have two options.
First option is to look at the I<SomeThing> interface definitions. A good starting point is the common interface implemented by the ChromiumWebBrowser class across both WinForms and WPF: https://github.com/cefsharp/CefSharp/blob/master/CefSharp/IWebBrowser.cs and then at the public interface of https://github.com/cefsharp/CefSharp/blob/master/CefSharp.Core/Cef.h
Second option is that all of it should be included as XML documentation files in the NuGet packages so it provides you with intellisense and documentation in the VS object browser.
I had hoped including the XML doc in the NuGet packages would have triggered http://NuDoq.org to generate pages, but so far no luck with that.
I created a VS 2010 class library. Marked the assembly for Com Visibility. Signed the assembly with a strong key. Created my class, have my entry point method available.
The library works fine from a test project in C#.
I regasm the class library to gac, via:
c:\windows\microsoft.net\framework\v4.0.30319\regasm testdll.dll /tlb: testdll.tlb /codebase
Include the tlb file as a reference in my VB6 project. I find it through resources 'browse' so its there.
When i try to instantiate the class... its empty. the public method that should be available via the public class doesn't show.
Dim objTest as testdll.testclass
set objTest = new testdll.testclass
objTest.testmethod <--- this 'testmethod' doesn't display in intellisense... nothing does.
In addition i tried calling the 'testdll.testclass' via CreateObject, i get the error "ActiveX component can't create object"
Now i have other projects i've done COM visibility for and i've tried comparing the difference, but i don't see any. I can't understand why it isn't working.
Any clues??? tx very much.
Just use an interface... one you define or to use the [ClassInterface(ClassInterfaceType.AutoDual)]
there are comments online you can find that indicate not to use autodual, but if you control the complete usage of your library, it seems like an 'ok' way to go.
I tried all sorts of ways to simulate / understand why my one project didn't need an interface to be visible by an vb project, without success. i had originally thought perhaps possible that it was because that project implemented an IDisposable Interface (the ONLY interface used in the C# projects that is com visible) but that didn't turn out to be the reason. Anyway I don't want to waste anyone else's time on this. thanks for the responses.

I'm using the Visual Studio UML designer to create some class diagrams. Since I would like to generate code from the diagrams it need to be accurate.
Now I'm trying to define the type of some properties of my classes, but I can't find a way to give them a type different from bool, string, int and UmlimitedNatural (and my own types of course). I found a tutorials that claims I would have to create custom stereotypes. Really? I mean it's VS, I'm just asking for some build in reference/value types like byte or GUID.
Do I overlook a hidden switch or if there is really now way to tell VS to bring up some commonly used types does anyone know a source for UML profiles that provide it? And how I can define more complex types like generics?
UML is implementation language neutral. Since types differ by platforms it is necessary to define an implementation language profile for any UML tool. Most UML CASE tools include the option to choose the language and apply a built in profile, which should make them available.
I am fairly new to development, and Visual Studio 2010.
I have a solution with a Test Project:
In my solution, there are two projects: "TPS" and "TPS.Tests"
In the TPS project, in the namespace "TPS.Models" I have defined a bunch of classes, and two interfaces.
I have created a Test Class in the TPS.Tests project, and have added "using TPS.Models;"
I attempt to implement the interface by typing it out (e.g. public class FakeObjectClass : IObjectClass), but it isn't recognised (so I can't get the auto-implement going, which would be handy as I have over 100 methods)
Typing in the class, in Intellisense, I can see all the objects defined in my model, but none of the interfaces.
Google has been unusually silent on the search combinations I have tried. I am hoping there is some simple explanation/fix?
Thanks in advance for your time.
Tim.
If you haven't specified an access modifier when defining the Interface, it will default to internal and not be visible to other assemblies.
Make sure that you defined your interface as
public interface IMyInterface
A few things to check:
- Does your "TPS.Tests" project have a reference to the "TPS" project?
- Are your interfaces in the "TPS.Models" namespace? Putting the files in a sub-directory of the project, such as "Interfaces", can affect their namespace.
- Are the interfaces marked as Public?
Also, I would suggest using an Isolation (aka "Mocking" framework) to create your fake objects, such as Moq, Rhino.Mocks, etc, rather than rolling your own fake objects for most situations.
My question isn't so much about use of interfaces but more of a project organization nature.
Note: I am using VisualStudio in a multi-layered application.
Should my Interface files live in a separate project from their implementations? My initial thought is that it would be useful to separate out all my service interfaces into their own project (and a project for my initial implementations) so that down the road the implementation/concrete project may be removed and replaced with a new one if necessary.
To clarify with an example: Suppose I have a business layer Interface called IBusinessService which lives in the MyApp.Business.Services namespace. My implementation FooBusinessService would exist in the same namespace, but a different project in VisualStudio. If later on the implementation needed to be reworked, a developer could remove the reference to the FooService.proj and replace it with a reference to BarService.proj.
This seems like it would declutter the app solution by allowing you to reference a project with only interfaces without also acquiring concrete implementations (which may be obsolete or of no use to you), but am I missing something?
I'm with you. I prefer to put my interfaces in a separate project AND in a different namespace. The classic example is with data access classes. You want to be able to code an MSSQL version and a MySQL version, both implementing the same interface. As such, I prefer that the interface definition be in a separate assembly/project. Here's an example of how I lay out assemblies and namespaces:
Elder.DataAccess.Core - contains the interfaces and common utilities
Elder.DataAccess.MSSQL - specific MSSQL implementations of the interfaces
Elder.DataAccess.MySQL - specific MySQL implementations of the interfaces
This allows me to modify the implementations without touching the project that contains the interface definitions. This helps me with version control and change tracking, too. There might be other ways to skin this cat, so I'll be eager to see other folks' answers.
