hi , i have a question
Can i import this dll files in the program itself in C# ?
Note : the program will not open without them !
Yes. Net 6 supports this, it's called a SingleFileApplication. see https://learn.microsoft.com/en-us/dotnet/core/deploying/single-file
What you’re referring to is called static linking. As others have mentioned .NET 6 has a concept of a “single file application” that can handle this for you. If you’re using .NET Framework then things get a little more challenging as there’s no out of the box mechanism to do this. Fortunately there are techniques that can make this work — from bundling the library DLLs as resources and extracting them on the fly or using a tool like ilmerge. This is covered in depth here: Static Linking of libraries created on C# .NET

I'm trying to add the Libspotify SDK to a test solution. However, I got the following error:
Now, I tried following the first answer of this question. However, all I got was:
The package of the library is structured in the following way:
Additionaly, my project is targeted to .NET Framework 4.0
And the configuration is done as follows:
What can I do to add this library?
EDIT:
Also, I found this link where someone explains that it need to be copied manually into the project output directory. I tried putting the .dll there, but I guess I have to modify something else to make it work. Any ideas?
The libspotify.dll you are trying to access is a Win32 C library, not a C# (.NET) assembly. As such, you can only use it through interop.
You don't have to do this yourself (judging by your question I'm assuming you have no previous experience with the techniques involved), you can use a ready-made solution like libspotify.NET.
All of my cross-platform libraries are created with solutions that have two projects: one that builds on the Silverlight CLR and one on the regular CLR. Hence, every library I make has two DLLs: name.dll and nameSilverlight.dll.
This is, as far as I know today, the only way to do it.
However, I recently tried Mike Talbot's "Silverlight Serializer" DLL, and I could include the same DLL in a C# desktop and in a Silverlight application. It's the exact same file.
How did he do that? And how can I do that?
(I really need to do it, because I'm trying to serialize in a desktop app and deserialize in a Silverlight app, and the assemblies are not matching up because they're different.)
It may be that they are using the Portable Library CTP.
Silverlight 3 is a "lowest common denominator" and if you just use base/core classes, you can compile a DLL there and reference it directly from .NET. You cannot, without the portable library, do the converse however.
I was told that Microsoft has released reference source code for some .NET libraries (I'm especially interested in C# libraries). If it is true, I would like to download that code and use it with my VS, so I can browse the code by selecting
Go to Declaration
and
Go to Implementation
from context menu. It would be much better then just to see documentation in object browser.
So how do I get VS to work with it? Thank you.

All you need is this: http://referencesource.microsoft.com/
Here's an article on MSDN and you may also checkout the following article and this blog post also. This allows you to step through the framework source code while debugging your applications. Reflector is also a good tool for browsing through the compiled assemblies.
Here is reference source code for.NET from Microsoft that available for download.
Here is how to set up VS for debuging.
Darin said nearly everything. The only hint that is missing is the NetMassDownloader to get the whole source once if needed.
here you go: .net source code download link
good luck in compiling it so you can debug through it like it was one of your own projects. I don't know how big a project you've ever worked on, but this one's a big one and its not as simple as you would imagine...
The .net core, .net 5 and .net 6 runtime code can be found here:
https://github.com/dotnet/runtime
This repo contains the code to build the .NET runtime, libraries and shared host (dotnet) installers for all supported platforms, as well as the sources to .NET runtime and libraries.
How can I check what objects, tools, variables, anything... are used from .NET 2.0 in a C# application.
How can I get a C# application run without .NET 2.0 ?
UPDATE:
sorry, I didn't clarify enought. Here's my situation: I have developed a pretty simple application in C#: embeded browser which displayes static webpages with an option of searching inside of these html pages. I'm using simple textbox, buttons components for this.
The application will be distribuited for people wich have very old PCs, even with windows 95. I would like the app to be runable on it, or at least on win 98, without telling the people to install .NET 2.0, as the users don;t really have PC usage skills :) .
I'm using a dataGridView as well.
You can have a look at this : http://www.remotesoft.com/linker/
"The mini-deployment tool puts
together the minimum set of CLR
runtime files and dependent assemblies
that can be simply copied to a single
folder on a target machine, and your
application runs as if the whole
framework is installed. Since the
installation is isolated into a single
folder, there will be no conflicts
with future .NET installation. When
linking is used for the dependent
assemblies, it will further reduce the
file size."
You may need to clarify a bit more.. do you want the app to run without .Net at all? Or you want it to run in .Net 3.5 without .net 2.0 bits?
If its the latter, then simply don't reference assemblies that are compiled in .net 2.0 (check the properties on the reference you have added). If its the former, then its really not feasable. Yes its possible, but it means deploying parts of the framework with your app, but then, you'd be deploying all the bits, including the 2.0 bits.
Your're question really needs more information though, it doesn't make much sense currently. Sorry. =)
To make sure it runs without .NET 2.0, compile it with the .NET 1.1 compiler.
But this seems like not a good idea. I'd recommend revisiting your requirements.
Win98 wasn't shipped with .NET. Using .NET v1.1 won't get you much more platform penetration than .NET 2.0, if any.
IT looks like windows 98 supports the .net framework. See this answer for details:
OS Compatibility for various .NET Framework versions
You cannot run a .NET application (i.e., that uses the CLR) if you haven't installed the corresponding .NET Framework binaries (i.e., that contains the CLR) directly or indirectly.
Period.
We wrote a small Windows class library that implements extension methods for some standard types (strings initially). I placed this in a library so that any of our projects would be able to make use of it by simply referencing it and adding using XXX.Extensions.
A problem came up when we wanted to use some of these methods in Silverlight. Although all the code was compatible, a Windows library can't be referenced in Silverlight so we created a Silverlight library that had links to the same class files and put compiler directives into the classes to allow different using declarations and namespaces. This worked fine until today when I added a new class to the Windows extensions library and realised that I would have to remember to link the class into the Silverlight library too.
This isn't ideal and I wondered if anyone might have ideas for a better way of sharing extension methods and other helper code between Windows and Silverlight projects.
You cannot set a reference from a Silverlight assembly to a regular .NET assembly but you can do so the other way round.
So create a shared Silverlight assembly and add your code to that assembly. Now you can set a reference fro both your regular .NET and you other Silverlight assembly to the shared Silverlight assembly.
The restriction is that you can only put code in there that would work on both the .NET and Silverlight CLR but that is no different from sharing code.
Since this question has been answered, there is a new solution from Microsoft, Portable Class Libraries. Here is the blog post where they announced it.
I'm just about to start playing round with them for sharing code between silverlight and some server side code I'm writing, so can't add too much past the links at the moment.
Silverlight runtime is different from the normal .NET runtime. So you need to do tricks at the project level to share code between multiple platforms.
Here's how I've done this for Autofac IoC container.
With this approach you do not have to create different projects for each platform being targeted.
PS: there is also a Project Linker tool from the Composite WPF that allows to link Silverlight and WPF projects (creates multiple projects). But it does look messy.
there is a similar problem with XNA projects. Since you can target several different platforms, you're required to have different projects. The reason for this is because the base class libraries that the project references are platform specific, so you can't have just one project.
If you're curious, you can get a bit of insight from this blog:
To recompile the source for another
platform, you need another project.
The reason for this is because the
projects need to reference different
assemblies for both the XNA Framework
and the underlying .NET Framework
(Xbox 360 and Zune use the .NET
Compact Framework), and C# projects
don't provide support for referencing
different assemblies for different
platforms.

I had some dependency issues when referencing to a Silveright class library in .Net.
An alternative way when using Visual Studio 2010 and WCF RIA 1.0:
Create a normal .Net library assembly.
Create a Silverlight class library. In the configuration of the assembly specifiy the first .NET library as the "WCF RIA Service link"
Put your code in the .NET library as "ClassName.shared.cs" files.
WCF RIA will handle copying the file to the Silverlight assembly.
