Can I create library (dll) project on ironruby ? and How ?

I'm assuming you're referring to creating a .NET assembly which you can use from other .NET apps. For that you can use the IronRubyEmbeddedApps project, which can be found here - https://github.com/rifraf/IronRubyEmbeddedApps

How to consume WinRT component inside Win32 dll project?

Using Registration-free WinRT it is possible to load WinRT components inside Win32 application.
What's the process to load WinRT component from inside Win32 dll? I tried the steps mentioned as part of Win32, but winmd files are not generating the corresponding header files.
Main usage scenario is dll can be loaded any application, like electron node addon or c# app etc.,
Without any changes to application, dll by itself should be able to consume WinRT component!
Did you add a reference to the WinMD file in the vcxproj and then installed the C++/WinRT NuGet package? This should make it generate the corresponding header files that your DLL project can then consume.
Following is the solution:
Was able to fix this in weird manner i.e. not a standard way to solve this.
Our use case was to use FFmpegInteropX inside win32 dll, so that we can use ffmpeg as a source reader and use the underlying hardware decode support. Mechanism is discussed detailly in the following link:
https://github.com/ffmpeginteropx/FFmpegInteropX/discussions/275#discussioncomment-3091100
Following changes were done to use WinRT component inside a Win32 dll:
Copied the WinRT generated files from the application to Win32 dll project
Before invoking any of the api from the generated runtime class, did LoadLibrary of the specific WinRT component into the dll
Now the make the necessary WinRT component call as it was done in standard win32 application
All modules were working as expected.
Above solution was copied from:
https://learn.microsoft.com/en-us/answers/questions/924996/how-to-consume-winrt-component-inside-win32-dll-pr.html
It's not a straight forward solution, also not sure if MS has any plans to add support for WinRT component inside dll project, if such support comes up then this may not be needed.

VS2015 C++ DLL and such with Add Reference

I have three VS2015 projects (DLL, C++ App & C# App)
I created the DLL and targeted v4.5 Framework
I created the C++ Application and targeted the v4.5 framwork and then was able to add reference without an issue.
I create the C# Application and targeted the v4.5 framework and then the Add reference fails with check your assembly or COM message.
Both applications have the DLL project added to the solution.
What else can I check as to why my C# process can't add reference?
Thanks,
Mark
I got around it using PInvode and the C# project didn't need to Add Reference afterall. I had to manually edit out the Precompiled header stuff to force that NotUsing. Thanks for the quick response... just had a quick turn around for my boss. Handed a working Cipher DLL for use with both C++ and C# in his project.

Reference from assembly to DLL in Visual Studio solution

Say, that we have .NET application App along with additional assembly ClassLibrary, which, in turn, uses native DLL called Library. All these are in single solution, so I may set up the dependencies etc.
The catch is, that I want the Library to be automatically "attached" to ClassLibrary, such that when my App references it, Visual Studio will automatically copy the Library to target bin folder.
Usually I did that by using pre-build or post-build events and adding custom scripts. But hey, all these are in the same solution. Is there simpler way to keep such native-dll-reference for .NET assembly?
You have to add the native library to your project. If the native library is in the Solution (not in the project) than it is there only for your reference. You have to add the native library to the Project because the project file describe the build behaviour.
Than add native assembly to the ClassLibrary project and then in properties set: Copy To Output Directory to Copy if newer or Copy always.

Why am I unable to add my PCL to my Universal App?

I get "Unable to add reference" when I try to add my PCL as reference. The projects are in the same solution. The error message doesn't say anything more.
When I try to add the .dll via Browse... I get the an error telling me that I can not add a PCL targeted at .NET Framework to a project targeting .NETCore.
What's wrong?
It sounds like the library you think is a PCL is not actually a Portable Class Library. It's just a .NET Framework library.
Try creating a new PCL and referencing that. See this MSDN page for information on how to create a PCL.
The error is that your PCL is targeted at .NET Framework and not .NETCore. .NETCore does only contain a subset of .NET Framework.
To solve this, replace your PCL project with a Class Library (Portable for Universal Apps).

Cannot add a reference to PCL from C++/Cli project

I have a Portable Class Library project, Net 4.5 platform activated. I can use it in other C# projects without problems.
Now, I have a C++/Cli project and I need to use some classes of the above PCL project.
When I add the reference to the PCL project, Visual Studio 2012 gives me an error because of different target platforms.
Is there a problem to add references to PCL projects from C++/Cli projects?
Thank you
This questionas was replied but for some unknown reason, the response has been deleted:
The solution is to edit the vcxproj file and change
<TargetFrameworkVersion>v4.0</TargetFrameworkVersion>
to
<TargetFrameworkVersion>v4.5</TargetFrameworkVersion>
