Include DLL into Exe [duplicate]

This question already has answers here:
Can a .NET windows application be compressed into a single .exe?
(12 answers)
Closed 9 years ago.
I am new to C#.
I am not a good programmer but I have worked on some projects which were in Delphi7. In Delphi there is one option; compile the class files to create .dcu. Those .dcu can be used without having the actual code with any other project in Delphi and after build .dcu files need not no given to end user.
Now my actual Question,
Is there any way where I can create some compiled file from my C# class and use that compiled unit with some other project in C# ?
I already tried to create dll and use. Nice Idea, but I don't want to give any other file than Configuration File and Executable file. Since, I created dll that needs to give with application.
I also tried to create a setup of application which build executable, configuration file and dll together. while executing, it extract itself in %temp% folder and executes from there only. So, In this case I am not able to set the configuration file's values.
Again the same question,
Is there any way where I can create some compiled file from my C# class and use that compiled unit with some other project in C# ?
Please suggest the solution
Thanks

Make it into a .dll. And then add that .dll as a reference in whatever project you want by clicking on References and then selecting Add Reference, and then in the Browse tab navigate to your .dll and select add. You will now have access.

Basically you need to combine all your DLLs and the EXE to a single EXE?
You can use ILMerge.
For more options take a look this question: Can a .NET windows application be compressed into a single .exe?

Class Library Intellisense not showing up after adding the dll to the references

In C#, I made a ClassLibrary that has one Namespace and one Class.
I saved it and build it.
in other Projects, when i use it, I add it to my references by browsing to the .dll location.
But The Problem is that its name is not showing up in the Intellisense.
i.e when I: using ... my dll doesn't show ..
I'm Importing the library to a ConsoleApp.
both of the App and the library target Framework is .NET Framework 4.0
and I made their Assembly Version 4.0.0.0 so they're the exact same.
is there a setting or something that I'm missing ?
how can i make it pop up ?
I'm using VS2010 Professional
Thank you for your help

Maybe this be usefull, I was having a similar issue, I have a Web project, add the reference to a Class Library by selecting the project, but if I made a change on the class library, I can´t see that change on the intellisense of the Web Project, after try many things, I see that in the recently added reference, the value of the option "Local Copy" was set "True", then I change it to false and everething works!

I had a similar issue but in my case it was a property on the class. If you go to the file properties and look for a Build Action. Somehow mine was set to Content it had to be set to Compile.
I am using Visual Studio 2013. I hope this helps someone else.

Is the namespace for your assembly different than the namespace for your currently open project? I've had times when the current project and an assembly share the same namespace path the intellisense can mess up.
In general, Visual Studio is pretty good about intellisense generation, especially for C#. But sometimes there are some interesting conditions regarding ambiguities, and especially mixing project types where it just doesn't quite work.
Placing your content in the same namespace makes me wonder if you've actually fixed the problem (it may just be autocompleting the namespace in the currently loaded project rather than the assembly), but if it allows you to continue working, then go with it!

Right click on project on which you add reference of your dll/project select menu project dependancies and select/MarkCheckBox for reference project/dll. then it will work fine.

If the class library project had its name changed after creation, then intellisense may fail finding it due to directory issues, I believe.
I created my class with the generic "ClassLibrary1" or whatever, and then later changed the default namespace, class name, and project name inside of VS2017. I closed VS2017 and changed the directory name to match my default namespace, and then re-associated the project file in VS2017, and then re-added the reference in my main project file.
All seems to be fixed now.

Question when adding a project to a Visual Studio solution

I created a brand new blank Visual Studio 2010 solution, and added an existing C# Project to it. I built the solution and it compiled correctly.
But when I go the solution folder, I see that the imported C# project is not physically in that folder. It seems it only references the project to wherever it is.
Is this intended? Should I even worry about this?
How can I create a physical import, meaning the project is copied to the solution folder?

How can I create a physical import, meaning the project is copied to the solution folder?
If you want to do this, copy the project to the solution (outside of VS), then add the local copy directly.
The default behavior allows you to share a project between two solutions. This is occasionally useful (if handled with care).

'How do I create a physical import?'
You don't - you're adding a project to the solution which will always result in referencing it in-place. In order to structure your solution you need to copy or move the existing project to the desired folder, created any desired Solution Folders to match the physical structure and then Add existing project as needs be.
The other alternative is to Add new project and then copy all of your project data over from the existing one but this will be prone to errors at some levels.

Adding an existing project always makes reference to the original. That makes sense in a lot of cases. If you want to use the project in a number of solutions and you want to make sure that they are always using the same version then you have the choice to either just reference the compiled library or have it available in each solution. If you do have it available in each solution then the risk is that you will make some mod of it in one solution that breaks the others. I am pretty good at doing this!
As mentioned already if you want to modify that project and don't mind if it gets out of sync with other versions of it then you need to copy it into your solution folder and then add it from there.
The version control software I use pretty much forces me to do that as it does not like code that is not located inside the solution tree.

Moving projects files in a .NET project

It's not code-related but IDE related. I'm working on a .NET solution with about 35 different projects. These projects need to be re-organized into a new folder structure. Why? Because about 10 of those will be removed and the rest will be divided in more logical units.
One way to do this is by creating a new solution, Drag&Drop the projects into a new folder tree within the Windows explorer and then just add them to the new solution.
To be honest, that sounds dumb!
Is there a way to just move projects into different folders from within the IDE? I've tried to "save as" the projects but the IDE won't accept a different folder.
It's irritating but because there have been a few wrong choices in folder names, I'm now stuck with those names.
Example: Right now I have a project main folder which contains child folders named "Client", "Server", "Business", "Database" and whatever more. Within those child folders, there are more child folders, each a three-digit number. Within each numbered folder there's a project which is named in some logical way, like Company.Business.Customers with additional logic within this project.
The problem is that not all projects now follow this naming convention and I consider it obsolete.
A project like Company.Business.Customers should just be in a folder named Company.Business.Customers in the project root so it's easier to recognize. The name already makes it clear that it's a business class for this project. The clear division within client classes, business classes and whatever more just needs to be arranged within the solution, but I want to flatten the file structure. (And remove some obsolete projects.) Basically, I'm not refactoring, I'm just cleaning up.
VS2008 doesn't seem to have such an option, though...

Fire up notepad.exe and open the .sln file. And start Windows Explorer, navigate to the solution directory. Observe how the .sln file content matches the solution structure. Edit the entries, make the corresponding change with Explorer. Backup first.

I don't think there's an easy answer here. Your main problem is going to be that Visual Studio (or .NET) doesn't care if you have classes that belong to a different root namespace sitting in a project.
So if you have a project called Project.BusinessObjects and another project called Project.DataObjects there is nothing stopping you from putting a class called Project.BusinessObjects.User into the Project.DataObjects project.
I don't know of any way of doing all of this without a lot of manual work. Resharper will help quite a bit if you use the 'namespace rename' feature, but you're still gonna end up with a lot of grunt work.

Also, be VERY wary of doing this in conjunction with version control systems. You have to know your version control system really well to know how it's going to react to such major refactoring.
Other than that, what you are describing doing is not all that difficult. You do have to edit the solution files and maybe the project files by hand, and you might need to remove a project from a solution and add it again when it's under the right directory.
I would make a backup, and then refactor away. I think it is a mistake to think that you can do everything you need from the IDE, though. And if you do what you describe from the IDE in a source control system that uses the old Visual SourceSafe API, you will certianly (guaranteed) mess up your bindings, that API is just not made for moving (or renaming, for that matter) files around in the way you describe. The best way to do this under that scenario is to remove all source control bindings and then re-add the reorganized solution back in.
It's not that difficult, you just have to prepare (do a backup) and experiment until you get it right.

I don't think there's any way to do this from within Visual Studio, and as #gmagana points out it's going to be very difficult to do if the files are under version control.
However, it is possible to do it manually.
Start by creating the new, desired folder structure - ignore the .csproj files and solution files for now, and more the .cs files you're interested in into the new structure.
Now, fire up Visual Studio, and create a new, empty project. If you have different types of projects, you might want to create one new, empty project for each type. This will leave you with an empty .csproj file, and a .sln file with just one project.
Copy the empty project file to where they're needed, and rename them as needed. You can edit them and change the Assembly name and default namespace if you want, or wait until you're done and change the settings with Visual Studio.
Finally, edit the .sln file, and remove the Project section. Copy the empty .sln file to where you want it, and open it up in Visual Studio. Now go and add each of your existing projects to the new solution.
Within each project, click the "show all" button, and start including all the files you've copied into the project structure. Resolve missing dependencies, change the namespaces and assembly names for the project, and make sure that the code files don't specify a namespace you don't want. Repeat until done.
Once you get the new solution to build, it will be helpful to open up the DLLs in Reflector in order to ensure that you haven't missed any namespace declarations in the code file - if you're trying to get to a point where there's a 1-1 correspondence between the DLL and the namespace, or even ensuring that no namespaces are split between DLLs, Reflector is your friend.
Good luck.

I've used the following solution to solve my problem:
I started with a new, empty solution in a new folder.
For every project that needed to be moved, I used the Windows explorer to create a child folder in the solution folder, this time with the proper name.
I copied the projects from their original location to their new folders.
I added all the (moved) existing projects from their new locations.
In the Solution Manager, I renamed the projects to a better name.
I fixed the project properties and other settings for all projects.
This did clean up the whole project quite nicely. I then added the whole project to Vault (Version Control System) and once it was in the VSS, I deleted the folder again (actually, just renamed it first) and retrieved it back from the VSS system so any obsolete binaries and other garbage was gone too.
It's a lot of work, but the result turned out exactly what it needed.

The best way to rename a project in Visual Studio 2008 [duplicate]

This question already has answers here:
How can I rename a project folder from within Visual Studio?
(42 answers)
Closed 8 years ago.
I always find my self in trouble with a lot of namespace or reference errors when trying to rename a project in VS.
This is how I do it: I click on the project and press F2 and rename it.
What procedure do you guys follow?
I used to work in Eclipse, and there I don't have the problems. Maybe it's easy in VS too and it's just me.

Try highlighting the root namespace in one of your files, and then hitting F2 and typing the new one in. This will perform a Refactor->Rename (also available via contextual menu), which should change that root namespace in all your files. Then, setting "Default Namespace" and renaming your project should take care of the rest.

Renaming the assembly should not be an issue, unless you have external projects depending on it. Within the same solution, it will carry on working correctly.

In the properties for the project, I can set "Assembly name" and "Default namespace", I think it's what I've been look for. I assumed that the namespace was automatically renamed also in that proces.
If i'm still missing something, let me know so I can accept your answer.
