DotNetBar c# app crash when opening in another pc - c#

I created a c# app just to test the DotNetBar components it works perfectly in my computer but when i sent it to a friend to tried the app crashes instantly.
do I have to move some dll files or something.
thanks

This problem is from the dotnetbar dll not being present on the second machine. There are two solutions that allow programs with dotnetbar to run on machines that do not have it.
You can go to references and change copy local to true (solution OP mentioned in comment on other answer). This includes the dll in every build which, in some situations, can make debugging builds more time consuming.
OR
You can go to Publish, open the Application Files window and change the Publish Status to Include. This will only include the dll when you publish instead of every build (generally more recommended option).
note: both of these are done from the project properties

I suspect that you have developed your Application in heigher version of .NET Framework and trying to run it on your friend mavhine which does not have the same.
Solution: try to find the .NET framework version which is being used by your friend and then target your application to the same version.
Follow the below steps to change the Taget Framework version.
1.RightClick on Your Project
2.Select Properties
3.Now Select Application Tab
4.Select Target Framework Version dropdown
5.Select the .NET Framework version xyz [here xyz is the .NET framework version used by your friend]

How to release a project with dlls and packages used in it in Visual Studio C# to use it on another PC?

I've just finished my Windows Forms App project in Visual Studio using C#. I know I need to release it. To do so I need to go from Debug mode to Release above in VS and then just click on F6. After that I have a folder with an exe file in it. But in my project I use a dll library which was copied on my PC and registered by regsvr32.exe in cmd. Next in VS I went to Solution Explorer and added the library in References by writing the path to it. I also use two packages which were installed by NuGet Package Manager.
My program is developed to use it by my coworkers so I have to distribute it to them. The problem is that I don't know how to prepare my app for it.
I'm reading lots of different articles about the release step but I'm getting more confused. People usually write that I can just copy the exe file in the release folder and use it in another PC after installing .Net there. But in my project there are also the three libraries and without them my program won't work in another PC. I can copy and register the first library on other computers but what about the last two? How to set up them correctly?
About the first library, I put it in a folder created by me manually in the C directory of my computer. The release folder is in another place. And when registering this library in cmd and then adding it to References, I specified the path to it. It means if the path has been changed, it won't be possible to use the library in the project. I tried some times. It's not convenient and when placing the app in another PC without VS where I can specify the path, my program won't probably work. So it would be very convenient to place this library next to the release folder and after putting it in another PC, the path to the library wouldn't cause any problems.
To sum up, I'm looking for the way to easily and conveniently distribute my program to users. Of course, I want to put my app and the libraries together in a PC, not to set up them separately and then tune them separately to make the program work there. Might there a way to release it as an app with all the libraries connected to it?
I feel it must be easy but I'm not so experienced. I'm sorry for that.
It is recommended that you use ClickOnce deployment:
ClickOnce deployment is a Microsoft technology that allows you to easily deploy your Windows Forms App along with all its dependencies. With ClickOnce deployment, you can publish your application to a web server or a file share and users can install it by simply clicking on a link. ClickOnce will automatically download and install all the required DLLs and packages on the user's computer.
Of course, there are some third-party packaging software that I can't recommend. If ClickOnce doesn't help you, I'll think of other ways.

Cross-compilation with Visual Studio 2019

I'm using VS2019 under Windows 10 and I'm trying to figure out how to compile for the non-Windows platforms. I'm aware that only some languages support cross-compilation (C# being one of them). So I decided to start off with one of Microsoft's own examples (the Console App for .NET Core). When asking VS2019 to create the Console project, it shows me various image icons which suggest that it'll be buildable for Windows, Linux and macOS - but no matter what I do, I can only make it build the Windows target.
After a bit of research I realized that I need to add this line to my C# project file:-
<RuntimeIdentifiers>win10-x64;osx.10.11-x64;ubuntu.16.10-x64</RuntimeIdentifiers>
but even after adding that line (and re-loading / re-building the project) it staunchly refuses to build anything apart from the Windows target. Over on CodeGuru, one of the devs there tried it for me (under VS2017) and managed to make it work - but I've tried it in VS2019 and also VS2015 and I can't make it work in either of them. Any ideas what I might be doing wrong??
[Edit...]
Thanks Magnetron - if I press Build->Publish I see a totally different dialog from the one you're seeing (and it's the same in both VS2015 and VS2019):-
Even if I follow the Next or Finish buttons I never see the Create Profile option :(
Go to Build > Publish, select Folder and click on Create Profile
Then Click on Edit and change the Deployment Mode to Self-contained. At last, you can specify the target OS in Target Runtime
You can create multiple profiles for each OS, and publish each one individualy as needed.
Edit:
The posted publish dialog is for a .Net Framework Console app, not an .Net Core one. The .Net framework is Windows only, you have to create your project as a .Net Core
Woohoo!! I just ran the VS2019 installer to remind myself how to uninstall (in preparation for tomorrow) and it told me there's already a 16.3.5 available. 16.3.4 only got installed a few hours ago but for the hell of it, I figured I might as well try the newer version - and it's now working !!!

how can I export a C# application from Visual Studio 2012 to run in other computers?

I just made my first C# application in Visual Studio 2012 and I want to export it in some way so other people could use it in they computers (including computers without Visual Studio 2012). How can I do it? I'm new at C# and I couldn't find anything that I could understand. Can someone explain or indicate some site with a good (and maybe didactic) explanation on how it works? I have only made C/C++ programs by now, and they I just needed the .exe file, but, based on what I could find, I need something else to send a C# program to others to use.
Sory for the bad English and thanks for those who help.
Right-click the project in VS 2012, and choose Publish... from the context menu. Publishing to a file lets you create an installer:
Choose a location in the file system to which you would like to save the installer
Click [Finish]
Wait for the publishing operation to complete
A Setup.exe installer file will be created at the location that you have selected in the first step of the publish wizard. Share the installer with the people to whom you would like to give your application.
After building your project, you will find an EXE file in bin\(Debug or Release)
Check also the .net framework that it is required in order for c# apps to run. You can find what framework your app is build in projext properties. If the target computer has an old os (XP) maybe the .net framework needs also to be installed
You need any computer that wants to run it to be windows, and running the correct version of the .net framework. If it's a program that's created with VS2012, that'll be .net 2.0 to 4.5.2. After that, you need to find the location of your program, and you can just copy the debug folder that you are currently running from, and your program will work.

Deploy .NET (C#) exe application on desktops

I develop application in C# with MSVC 2010 Express, with Forms/WPF/etc.
Application consist of some private assemblies (maybe DLLs) and .exe file. It uses .NET 4 features.
How I deploy this application to other computers? Of course if they have .NET 4 I just can send zip of .exe with .dlls and it work. But if they don't have .NET at all (on Win XP machine)? Or maybe they have lower version of .NET? Should I point them to install .NET from internet or package it with my app or what?
Thanks
There is click-once deploy from microsoft. It automates most of the tasks, including making sure you have the right .Net version and updating the app if a new version of your app is available.
You should create a installer package. If you are using the express versions of visual studio, you can use some free tools for this like WiX or Inno Setup. WiX is perhaps a difficult option to start with, but has a lot of flexibility. There are tutorials and example projects to modify to adapt them to your needs.
http://www.tramontana.co.hu/wix/
This tools create installers that can check if a certain version of the .NET framework is installed on the user computer, among other conditions. You can also include the .NET redistributable in your package, or point the user to download and install it.
We try to keep deployment as simple as possible, and one of the things we do is to ensure our application is just a single executable, no support files needed.
We several steps to get there:
Make sure all dependent resource files are stored in embedded resources where possible, and not on disk
Use ILmerge to link all assemblies into a single executable
Optional - obfuscate the assembly
Optional - If some parts cannot be ILMerged or obfuscated, forcing us to have multiple files, we use Xenocode's PostBuild to link all files into a single executable. Xenocode offers a virtual filesystem to do this. This also allows framework embedding so your app will run on a clean Windows install - no dependencies need to be installed :-)
Wrap the single executable into an msi installer using WiX
Wrap the single executable into click once deployment. For this we also use a little stub launcher executable which starts the main application, allowing us to reuse the same main application executable
Create a zip file of just the single file executable for manual installation.
We the following on our downloads site:
the MSI installer - we prefer people to use this one
A zip file with the Xenocoded (single file) executable
A zip file with the Xenocoded (single file) executable including the .NET Framework

Yes, you should point them to install .NET. Otherwise it won't be possible for them to run your application.
You didn't say what type of clients they are (are you making a small app for your friends to use or are they paying customers), but whatever the case may be, I'm always completely against sending a zip file with an instruction document describing what to do with it and what folder to extract it to. As Remy said, ClickOnce is not a bad idea, but I've found it to be a bit of a pain to set up (once you get it set up, though, it works just fine). On the other hand, a Deployment project is simpler and if I were you, that would be the first thing I'd explore.
Use xenocode here
http://spoon.net/Studio/
No need to install anything.
It converts your exe to Native code indirectly and you can run anywhere on windows system.
It also has some option of adding framework inside and the total exe size will be somewhere arround 10MB + Your application exe size..
Thanks
yes! you have to give some general instruction about prerequisites to run your software and in that you can mention the Framework version 3.5 or 4.0 and other utilities you require.
please refer this document for Choosing a Deployment Strategy in Visual studio 2010 may this can help you
http://msdn.microsoft.com/en-us/library/e2444w33.aspx
when you package you application,you shoud include the .NET Framework
Check out Inno : http://www.jrsoftware.org/isinfo.php
It's free and pretty simple.
OTOH I've seen QTTabBar using it in its' codebase and it was literally one single text file (setup.iss). Let me see if I can find URL to their SourceForge page so you can see the source and the build ... There is it http://qttabbar.svn.sourceforge.net/viewvc/qttabbar/trunk/Install/ If you grab the source tree you can probably re-fit it for your app in a day.

Deploying C# (.NET 2.0) application as a portable application?

Is it possible to deploy a .NET 2.0 application as a portable executable?
So that my program can be ran in a Flash Disk without the .NET Framework 2.0 installed in the target machine. Or maybe is it possible to distribute my program with the required .NET DLLs, so that no framework installation is necessary?
I know that there are some alternative tools to turn my .NET exe into a single native executable like RemoteSoft Salamander, Xenocode Postbuild, and Thinstall, but unfortunately I can't afford one.
I also tried to embed the dependencies with Mono's mkbundle, but it messed my program up =\ (no XP visual style, broke some controls and its functionality)
Any kind of help would be appreciated :)
Thanks.
fyi: my IDE is Microsoft Visual C# 2008 Express Edition with .NET Framework 2.0 as the target framework.
Well, other than things like Salamander and Thinstall (now VMWare ThinApp) you would have to have .NET installed if you really want to run .NET.
It may be possible to run Mono without actually installing it (not statically linking your program, but including Mono on the flash drive). I suspect it would be tricky though, as you'd have to tell the runtime about things like the GAC location.
I can't see anything in the Mono FAQ about this, but you might want to ping a Mono mailing list - it sounds like a potentially interesting and useful thing to be able to do.
No; you need either the framework installed, or the tools like you have mentioned.
You could potentially look at mono's new static linker, but that is about it...
I have not tried this myself but here's the procedure:
Make a C# project.
In Solution Explorer, inside your project, there is a line "Reference". Click the plus near it. Now you can see all the dependencies of your project. Delete all references that aren't used (delete, and try to run/build. If it is possible to do it, that it is unused. If there is an error, return it by adding it (right mouse click, "Add Reference")).
For each reference, go to Properties, and in the property "Copy Local" choose "True". For each Image, Icon... make like to the referenced.
Rebuild you project. Now in your Build/Release folder (inside bin) you will see many dll files. Those files have the information of every resource.
Copy all the files in the folder (from step number 4) into a new folder.
Go to the folder: "\Microsoft.Net\Framework\" and copy the file "mscrolib.dll" to the new folder from step 5. If you don't find this file, you can always make a search in the Hard Drive which contains Windows folder.
Now your app is portable (with the whole folder content).

Well Thinstall is very expensive and it doesn't work in all situations. If you want to run your app without .Net installed you might run into trouble although there are tools that do that Xenocode has a tool that can do this for you and it's cheaper than thinstall.
But if you ask my opinion it's a bad idea to use them. Better convince your target market to install .Net 2 (Which is pretty much universal these days), and then pack all of your library files into one file using a cheaper Obfuscator like tool (There's a good one from Smartassembly.)
I've used Thinstall for a long time, and I've worked on this technology a lot, so I am not shooting off without experience.
