1- Put Book1.xlsx file to the Solution Explorer by following Add > Existing Item
2- Set properties of Book1.xlsx in the Solution Explorer like following ;
Build Action: Content
Copy to Output Directory: Copy Always
3- Run this project and see if Book1.xlsx file is copied to the the Debug folder
4- Close this project.
5- Open Book1.xlsx file manually by finding it in the Debug folder. Keep Book1.xlsx file open.
6- Run this project again and see the following error;
Could not copy
"C:\Users\onsuz\OneDrive\Desktop\WpfApplication1\WpfApplication1\Book1.xlsx"
to "bin\Debug\Book1.xlsx". Beginning retry 1 in 1000ms. The process
cannot access the file 'bin\Debug\Book1.xlsx' because it is being used
by another process.
As you can see if a curious person opens Book1.xlsx file manually before my application start then my application crashes.
Do you have any solution?
This is not your application crashing, this is your application failing to compile as it cannot overwrite this file. This particular issue will not happen at runtime as you will be deploying a pre-compiled version of your code.

I'm running into a problem publishing/installing a ClickOnce application being built in C# in Visual Studio 2019. The application is being built using .NET Core 3.1 and WPF.
I have an icon I am using for the application that is included in the project with the filename "loader.ico". The ClickOnce manifest is calling out for loader.ico, but the required Loader.ico.deploy file is not being generated when publishing, which is throwing an exception when trying to run the setup.exe to install the application to a client PC (actual filepaths have been replaced with [Path]:
+ Downloading file:///[Path]/x64/ClickOnce/Application Files/.NET Bootloader_1_0_0_4/loader.ico.deploy did not succeed.
+ Could not find file '[Path]\x64\ClickOnce\Application Files\.NET Bootloader_1_0_0_4\loader.ico.deploy'.
I have attempted a few things using what information on the problem I could find:
I set the Build Action for loader.ico to Content and set Copy to Output Directory to Copy Always. I also set the "Settings>Application Files" setting for loader.ico to Include. This has no effect on the resulting Publish, and no loader.ico.deploy file is generated.
I also receive the following in the output window when publishing:
Unable to apply publish properties for item "loader.ico"
I have also tried excluding loader.ico from the "Application Files", but this does not remove the reference in the .manifest file.
So now I am at a bit of a loss. I don't know why it would demand a .deploy file for the icon (I'd think it would just be embedded? No need for a separate icon file?). I can't seem to get the ClickOnce publishing process to generate the required loader.ico.deploy file, and I can't seem to get the manifest to remove the reference to it. What settings could be used to force the generation of this .deploy file (or force the manifest to not reference it)?
I had the same problem your application .ico file causes this error so you have to change its properties setting to Build Action: Content and Copy To Output Directory: Copy always.
hope it works
I can confirm from my very own experience how frustrating this is. I have tried anything and everything.
For the time being - until this issue is sorted - I am suggesting that you manually add the .ico file to the Apllication_1_0_0_x folder and appending '.deploy' at the very end.
So file will look like 'my-icon.ico.deploy'.
It works. Tried and tested.
In my case it helped:
Publish -> Show all (Settings current project) -> Settings -> Application Files -> (Show all files):
Find ico file, select publish status to Include | (Required) | Include.
From now on, the ICO file will be added when publishing
Additionally to the icon loading problem that I initially "solved" with Avrohom's method, I faced some issue with WebView2 not working / being loaded.
Both of these problems stopped when I disabled the click once publishing profile (.pubxml) option for producing a single EXE file:
<PublishSingleFile>False</PublishSingleFile>
Tested with .NET6, Visual Studio 2022
I was wondering if someone could please help me with something.
The main idea is that I want to have a .NET Framework Console App, which is build and packaged into a single file (an archive or something similar, like a jar file in the java world, containing all the referenced .dll files, sources files and additional project files) that i can deploy on another machine.
I've build an Console app using .NET 4.7.2 which is receiving data from a remote server and it pushes it to RabbitMQ. I use a .p12 file to authenticate to RMQ, which i keep stored in a sub-folder in my app called "Others".
When I run it from Visual Studio 2019 it works, but when I try either to release it and run it from that folder or to install it on my windows 10 machine it does not work anymore. It gives me the following exception :
RabbitMQ.Client.Exceptions.BrokerUnreachableException: None of the specified endpoints were reachable ---> System.AggregateException: One or more errors occurred. ---> System.Security.Cryptography.CryptographicException: The system cannot find the path specified.
...
When I publish the app, via the publish window, I select an output folder and I get the following files and folders :
(folder) Application Files
(file) setup, type of file - Application.exe (.application)
(file) ConsoleApp, type of file - Application Manifest (.application)
The RabbitMQ .dll file, which contains the RabbitMQ Client is located inside the folder "Application Files\ConsoleApp_1_0_0_13" together with other .dll files and a subfolder ("XMLRequest") but does not contain the other subfolders of my project.
I don't have the possibility to add these subfolders, where my .p12 key is located, i.e. "Others", in the publish screen of the application.
The other case when it does not work is when I to copy the whole "Release" subfolder into another location and just run the ConsoleApp.exe from there. I get the same error message.
Does anyone have an idea ?
Thanks !
Try following:
Open the project in Visual Studio
Go to Solution Explorer --> Click on Project --> Click "Show All Files" menu in Solution Explorer Menu
All the folders in your project will appear with dotted border in your project files tree
Right Click your folder and click "Include In Project"
Navigate to your file by expanding your folder in Solution Explorer
Right click file and click "Properties"
In Properties windows select "Copy always" for "Copy to Output Directory"
Performing above steps will cause Visual Studio to copy your entire folder to output (Debug and Release) directory.
There is also another option to publish required files during build and release process. Right click your required files and click properties. In the properties window set appropriate value for Build Action property to the value that you need. Following documentation describes when to use which Build Action Values.
https://learn.microsoft.com/en-us/visualstudio/ide/build-actions?view=vs-2019
Packaging your app as a single .exe file
If you want your .NET Framework Console App, to be packaged into a single file, then I would take a look at the nuget package Costura.Fody. It will package up all the projects DLLs into a single .exe for you. I use it all the time.
All you need to do is add the nuget package to your project like this:
PM> Install-Package Fody
PM> Install-Package Costura.Fody
and out will pop a single .exe
Embedding Resource Files - Option #1
If you want to include files in your deployment, what I have done in the past is embed them in the exe themselves and then extract them when the app runs.
To do this, add the files to your project as normal:
Then right-click the file and select "properties" and set the build action to be an "embedded resource".
This will alow you extract the file later on, when the program is running. With this setup you could have any number of resource files setup in the app.
Then on startup of the app, you can extract the embedded resource to a file on disk using a function like this:
public static string GetEmbeddedResource(string resourceName)
{
string resourceContents = "";
try
{
string[] names = Assembly.GetEntryAssembly().GetManifestResourceNames();
string resource = "";
foreach (string str in names)
{
if (str.ToLower().Contains(resourceName.ToLower()) == true)
{
resource = str;
break;
}
}
if (string.IsNullOrEmpty(resource) == false)
{
using (StreamReader sreader = new StreamReader(Assembly.GetEntryAssembly().GetManifestResourceStream(resource), Encoding.Default))
{
resourceContents = sreader.ReadToEnd();
}
}
}
catch (Exception ex)
{
throw;
}
return resourceContents;
}
with the usage of the above function looking like this:
var resource = GetEmbeddedResource("SomeFile.txt");
and then you can write the file to anywhere you need it on disk.
Embedding Resource Files - Option #2
The other option would be to copy the embedded resource to the output folder but then that means you wont have a single .exe file if you are manually copying this from machine to machine.
Embedding Resource Files - Option #3
If you are using ClickOnce technology to deploy your app, which it looks like you are, then when you go to the publish tab, if you select the "Application Files"
you can then choose which files to include in the deployment as seen here.
I have this WinForms application that uses an external dll file (Winppla.dll) so I can print tags in my Argox printer. Since I cannot add the dll file as a reference to the project, I use the command [DllImport("Winppla.dll")] on my class.
When I run the project in Visual Studio, it works perfectly.
Then I published my application using ClickOnce and when I try to run the application, I get the message error saying that the Winppla.dll could not be found, even though I am running it on my machine.
I tried to:
copy the file to the bin folder of the project before publishing
copy the file to the packages folder of the application before publishing
copy the file to the latest version folder on the Application Files folder (on the publishing location of the application)
add the file as a resource on the project
add a folder with the file as a Reference Path on the project
but none of these worked.
This project also uses SAP CrystalReports, and it works just fine.
Any ideas about how to make it work?
Following #Bearcat9425 instructions in the comments section of the question, I finally solved the problem:
Copy the file to the project folder and include it on the project
(on Solution Explorer, click on 'Show All Files', then right-click in the file and select 'Include In Project')
Mark the file as one of the application files on my publish tab
(right-click on my project and select 'Properties', then go to Publish tab and click on 'Application Files' and make sure the Winppla.dll is marked as 'Include')
Copy the Winppla.dll file to a shared folder in our server (I placed it on the same folder where I placed the setup of my application)
On each DllImport command write the complete path to the file shared location: [DllImport(#"\\the-path-on-the-server\Winppla.dll")]
Publish!
I have a folder in my main project that is separate than the Resources folder but also has some resources it that I would like to copy to the output folder as I reference it throughout the app.
I have set the build action to Resource, content, embedded content.. tried them all..
Also set it to always copy to output directory.
Now, from within my application I'm entering
AppDomain.CurrentDomain.BaseDirectory + "Dashboard\\Role.xml";
or also
"..\\..\\Dashboard\\Role.xml";
for the path and get an exception that says that the file can not be found.
Both of these paths work in my development machine but not once I deploy through click once.
I have tried to add it to the application files in the publish section as suggested in another post but it does not appear there.
I have also tried to put it in the resources folder and still nothing.... any ideas?
I followed some steps in this link and got it working:
https://msdn.microsoft.com/en-us/library/kzy0fky2.aspx
Basically, you mark the file as build action "Content" and set it to always copy.
Then, you go to the application files in the publish section of your clickonce application and they will now show up.
Switch them from datafile to "Include" and you're set!
In my Visual studio 2008 project, I've added app.config file where I store some app-data in xml format.
I read this data in code like this:
string somedata = ConfigurationSettings.AppSettings["somedatakey"].ToString();
when I start application in Visual studio, it works. But if I try to run the exe file (release or debug) I get error (if i debuf it it breaks on the line above):
Object reference not set to an
instance of an object.
The file app.config is not inside folder.
Is the app.config file in the same folder as your exe? If not, copy it there.
Starting debugging in visual studio builds everything, and copies the output (including app.config) to the output folder, starting it from there.
#Jullin: When you run project from visual studio editor by pressing F5 then CLR pick app.config file to read data but when you want to run project from .exe (bin/debug or bin/release) then clr read applicationName.exe.config, which you must have within your debug or release or any folder from where you access you applicationName.exe.
Like i have a window application named "WindowsFormApplication", when i build it successfully in release folder i have WindowsFormApplication.exe and WindowsFormApplication.exe.config and some other files. so make sure you release project successfully and your release folder must contain files.
While Running in from the Exe make sure that u have added app.config should be in the same directory
