I started learning c# a couple days ago and want to send my first program to my friend but as a standalone exe file that can be shared through google drive.
I've found several solutions but I coudln't understand any of them. Is there a simple solution to compile an exe file or a standalone app in visual studio 2019 that would just work when you open it
One annoying thing with .NET Core is that when you build it in Visual Studio it makes lots of separate files, which is annoying for portability.
A fix to this is to right-click on your project in Solution Explorer and click Publish. Select Folder Profile, give it a name and save it.
After that, you will need to edit the target runtime option, and set it to win-x86. After that, you should see a dropdown box at the bottom of the dialog, expand it and check 'Produce a single file'.
Then you can hit Publish and it should produce a single file.
NOTE: This does not work in .NET Framework, only .NET Core.
All you gotta do is simply build the project within Visual Studio, once that's done. Go to your projects folder and go into bin/Release (or Debug if you've selected debug build)/myprogram.exe. It should make a standalone .exe file!
Maybe this could also help you.

Hi i'm new in Windows Service c#. i followed tutorials and it works perfectly after installation.
Now my problem is when i modify the fonctionnality of the service (modifying c# code), and i uninstall & install the windows service, the functionnality remains that of the first installation.
I even restarted the PC and the functionnality and the functionality has not changed
Is there someone who had this problem?
I also had the same problem.If you are using visual studio installer, just delete the .msi and setup.exe from "XXX\Release" folder and rebuild visual studio installer project. It will recreate both files with updated code changes.
Right click solution > rebuild. Then run your service again.
In order run the updated service in Windows which is created in c# follow below steps
First of all stop that service in windows service manager (services.msc)
Then go to build menu in Visual Studio and click on Rebuild Solution
Then go to services and start the service again.
In this way the updated service will run if it is build successfully and the service is created accurately otherwise you will get Service Failure alert in Windows with specific error code.
I had the same issue and the solution I tried is different from the marked answer.
Right click the setup project (you get a popup window). Click Configuration Manager button at top right, from Active solution configuration dropdown, check whether the selected value is Release. If it is Release then Release folder is updated on building the project; else Debug folder.
Hope this will help a few having such an issue.
I am having problems debugging my web applications.
When I try to Debug my website I get an error saying:
The system cannot find the specified file
Now when I try to Debug again, there will be no error and it tries to open the page, but it doesn't load because IIS is not on.
And when IIS is on and I press the debug the page loads fine, but it doesn't hit the breakpoints I set.
Also the start button doesn't say "Google Chrome", but just "Start"
I thought this was only with this project, but this also happens in my other ASP.NET MVC Project.
I've tried restarting Visual Studio and my laptop, but that didn't solve it either. I also tried cleaning and rebuilding the solution.
Has anybody experienced this problem before?
Your problem with the Debug button showing "Start" occurs only if you set the Application Startup¹ to:
a WPF project or
a WindowsForms project or
a ClassLibrary project or something like this.
Otherwise, your WebApplication project or solution needs a review. Did you check these files?
If not, check the configurations.
See the Start Action in Web as the image below².
Another tips I can give you is to always Build your project during coding to see if everything is OK and sometimes do a Clean Solution and Rebuild it.
When something is not correct, try restarting your Visual Studio or disabling some extensions.
Also, here are a few questions to help you too:
F5 or Start Debugging Button is Greyed Out for Winform application?
Error while trying to run project: Unable to start program. Cannot find the file specified
Some of the answers even when not accepted can help you clarify why did you get this issue.
Hope this can be useful and I am glad you've solved the problem. Now, try to understand it.

You can set the Application Startup project by right-clicking the project in the solution and then click "Set as StartUp project".
To view the Project Properties as shown, right-click the project in the solution and then click "Properties" or select the project in the solution and use the shotcut ALT + ENTER.
I'm having a problem with a web application where the events in the global.asax class aren't being executed when I build the application through our build server and publish the website. In Application_Start is a single line of code sets up our logging, and in Application_Error I have some error handling code. Locally it all works fine, and if I copy the files directly from my development folder to the server rather than publishing it via the build server everything works fine.
From loads of Googling it would appear that this is a problem with the precompiledapp.config file being missing - sure enough it doesn't exist anywhere. However, nowhere can I find out how I actually get the TFS Build Server, or Visual Studio (2010), to create this file so that I can publish it.
Any advice on how I can generate this file would be much appreciated.
EDIT: A bit more information. I've just tried publishing the website through Visual Studio 2010 rather than the build server and this created the precompiledapp.config file. I copied all the files across to the server (except web.config which I left intact) and it logs successfully (which suggests the global.ascx events are being fired). What I need to do now is try and get the build server to do the same thing - any ideas?
Make sure your custom config file is set as a content file and Copy To Output is set to Always in the config file properties in Visual Studio.
I seem to have resolved this issue now.
As I mentioned in the Edit of my original message, when I published the website through Visual Studio 2010 to a local folder it created the Precompiledapp.config file, and copying the folder contents to the test version of the application got everything working. As I can't seem to get the TFS Build server to create this file, I decided to try just copying the file from my local publish folder to the test application, along with the rest of the files from the tfs build, and everything seems to be working as it should.
So although I've not managed to figure out how to get the build server to generate this file, my main issue is resolved and I'm able to use the global.asax file again.
I'm late to this question BUT you should probably verify that you have the correct SDK that visual studio would use to build the precompiled app (I think it's Azure SDK even if not doing anything with Azure but not 100% on that).
If you have visual studio installed on the build server you can just install the web workload (opening the solution will prompt it). I did this with Visual Studio 2019 today. MSBuild was ignoring not only my *.pubxml settings but even passed in properties via command line arguments to msbuild.exe (which overwrite the ones in the *.pubxml file).
I opened Visual Studio, it prompted me to install the necessary workload and I did. Everything started working as expected after that.
To precompile, in your pubxml file make sure to have this:
<PrecompileBeforePublish>True</PrecompileBeforePublish>
Also, this post refers to your Edit comment about how to get the build server to do it when it works on your machine.
I'm using VS 2008. When ever I make a change in my code and try to compile I get the following error:
Error 7 Unexpected error creating
debug information file 'C:\Documents
and Settings\jbezanson\My
Documents\MyProjects\DispatchBoard\DispatchBoard\obj\Debug\DispatchBoard.PDB'
-- 'C:\Documents and Settings\jbezanson\My
Documents\MyProjects\DispatchBoard\DispatchBoard\obj\Debug\DispatchBoard.pdb:
The process cannot access the file
because it is being used by another
process. ' DispatchBoard
Using Process Explorer, it is always devenv.exe that is locking the file. If I run in Release mode this does not happen. It started 2 days ago when I started a WPF application, and since then it happens with every application I work on.
The only info I could find from Google was referring to a bug in VS 2003.
Anyone else have this problem? How do I fix it? It is getting very annoying having to kill the file handle every time I want to compile.
If you have multiple instances of VS open, close other instances (apart from the one you are trying to compile) - this may resolve the issue.
When I have problems with locked files, I use Unlocker. (If you tried everything and it's not working, try this ;)
In case of broken link, here's a mirror.
Have you tried closing VS, deleting obj folder then restarting VS?
I had the same problem this morning and noticed that I had another project open that had a reference to the one that would not compile or debug. I removed the reference (as I didn't actually need it) and it was fine.
I changed the 'StartUp Project' of my solution to a project without reference to the locked file's project.
This solved the issue for me using VS 2010 SP1.
(Process Explorer said msvsmon.exe (started by devenv.exe) locked the pdb file.
After changing the startup project the processes msvsmon.exe and .vshost.exe disappeared and so did the file handle.)
Alex Clark, thank you for pointing me in the right direction.
The only thing that worked for me is to remove the optimizeCompilations="true" attribute from on the compilation element in my Web.Config file.
Compilation time may be a little longer, but it worked well.
To avoid that problem just open the project properties, go to Debug tab an untick "Enable the Visual Studio hosting process"
I had this issue today. In my case, I had just grabbed the data from my company's source control and instantly hit this issue when I tried to compile the project. The issue ended up being that the \bin folder was set to Read Only. To solve the issue, I just made the folder not Read Only.
I just came across the same problem today. And then I realized what went wrong: I had couple of Visual Studio windows opened at the same time, and one of them was in debug mode.
When I stopped debug mode in that one, the problem was solved.
That happens when you have a "fistfull of VS windows" opened.
Right Click The Folder that contains debug .pdb and uncheck the folders read-only propertys then ok. thats it.
This works for me with web projects in Visual Studio Express 2012 for Web:
Press F5 to begin debugging
"Do you want to execute last successful build?" - hit YES
At this point you could try a request - not sure if this step is necessary
Hit the stop button
Recompile successfully
I have solved a similar problem by adding these lines as a pre-build event:
if exist "$(TargetPath).locked" del "$(TargetPath).locked"
if exist "$(TargetPath)" move "$(TargetPath)" "$(TargetPath).locked"
With proper modifications, it might help your problem.
Since you say you have it on all applications you work on it sounds like a more global problem. You could try and reinit the vs2008 by writing
devenv.exe /setup
Edit: link to command line options
This worked for me. What I done was that close my visual studio and delete the .suo file and then re-open the solution. The locking should be disappeared now. Cheers.
Old topic, but something that worked for me. I had 2 projects in my solution, a class library type project and a windows form project. The windows form project was referencing the compiled binary and not the project itself in my case which was causing the lock. After changing the reference to the class library project, it worked properly.
Not need to restart or delete the file.Deleting will not be possible , you will get error message. Just rename the file and that is enough.
VS2010 will create another file for you as it wont find the origional. :)
I had the same issue from time to time. Usually no problem but once in a while... This particular time, it was impossible to work. I would shut the application down, and even that didn't work most of the time. I saw this post and a person said they had no issues until they started a WPF application. I was playing music (radio station) in the background with Windows 8 "Music" app. I had the idea that it was a Microsoft App built with Visual Studio. Once I stopped playing music, I never encountered the error. If you are reading this, see if you have any Microsoft apps running.
I also had the same issue. Tried all the suggestions above with no luck. I eventually change the Build Configuration from Debug to Release, the solution built...
This problem started occurring for me after changing from Cassini to IIS Express as my platform for debugging.
Cassini was much better than IIS Express but doesn't properly support the Integrated pipeline. IIS Express is hopeless.
This seems to be some sort of race condition in Visual Studio or IIS Express. It is nothing to do with one project locking another project - the locks are coming solely from the activity of the web application's build process.
Anyways, none of the above solutions worked for me. Unlocker doesn't seem to be supported for Windows 8 anymore. So instead I tried LockHunter. What I do is keep the LockHunter app open all day. If I get a complaint about some file being locked I copy and paste the file path into LockHunter then try again. This usually sorts out the problem but sometimes takes a few attempts.
