I'm trying to create a single exe distributable of this basic little application:
using System;
using System.Windows;
namespace BlackScreen
{
public partial class App : Application
{
[STAThread]
public static void Main()
{
App app = new App();
Window window = new Window();
window.Show();
app.MainWindow = window;
app.Run();
}
}
}
My csproj file contains:
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<OutputType>WinExe</OutputType>
<TargetFramework>net7.0-windows</TargetFramework>
<Nullable>enable</Nullable>
<UseWPF>true</UseWPF>
<PublishSingleFile>true</PublishSingleFile>
<IncludeAllContentForSelfExtract>true</IncludeAllContentForSelfExtract>
<IncludeNativeLibrariesForSelfExtract>true</IncludeNativeLibrariesForSelfExtract>
</PropertyGroup>
</Project>
However, when I run dotnet publish -r Release I get dozens of files in the Release folder, not a single exe file. If I take just the exe file out of that folder and place it somewhere else it doesn't run, so clearly those dozens of other files are required.
In older answers to similar questions the recommended approach is to use ilmerge, however, that has now been deprecated. Is there an alternative or is creating a self contained exe file no longer possible?
The following project file:
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<OutputType>WinExe</OutputType>
<TargetFramework>net6.0-windows</TargetFramework>
<Nullable>enable</N7llable>
<UseWPF>true</UseWPF>
<IncludeNativeLibrariesForSelfExtract>true</IncludeNativeLibrariesForSelfExtract>
</PropertyGroup>
</Project>
...and the following command...:
dotnet publish -c Release -r win-x64 --self-contained -p:PublishSingleFile=true -p:PublishReadyToRun=true
...can be used to create a self-contained and single-file deployment WPF app.

I'm building a project with the following in the CSPROJ file:
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>

I'm interested in debugging a source file in this project using Visual Studio 2019. Here are the details:
When I start the project without debugging, it compiles and runs fine. However when I place a breakpoint in my source code and I try to start with debugging, it basically runs my program and never stops at the breakpoint.
In my output window in Visual Studio, the following message appears:
The target process exited without raising a CoreCLR started event. Ensure that the target > process is configured to use .NET Core. This may be expected if the target process did not > run on .NET Core.
The program '[25444] basic-example.dll' has exited with code 0 (0x0).
However, I am intentionally setting the target framework to netstandard2.0. I.e. I would really like to debug it with the current project file.
Why won't Visual Studio allow me to debug this project?
Thanks to #LukeBriner's and #Dai's comments I was able to solve the problem.
As #LukeBriner mentions:
If you want to debug into it as a netstandard library then just create a dotnet core console app and call into the library in a normal way.
So that's what I did.
I had to rename all methods named Main in my class library to something else (I used Run).
I added a console app to the solution adjacent to the class library and added a project reference to the class library.
I imported the class library in my console apps' Program.cs with a using statement. I called the class I wanted to debug in the Main method of Program.cs
I modified the project file of the console application to look like the following:
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<OutputType>Exe</OutputType>
<TargetFramework>netcoreapp3.1</TargetFramework>
<RootNamespace>call_basic_example</RootNamespace>
</PropertyGroup>
<ItemGroup>
<ProjectReference Include="..\openxml-exceptions\basic-example.csproj" />
</ItemGroup>
</Project>
I modified the project file for the class library to look like the following:
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<PlatformTarget>AnyCPU</PlatformTarget>
<TargetFramework>netstandard2.0</TargetFramework>
<RootNamespace>basic_example</RootNamespace>
<ImplicitUsings>disable</ImplicitUsings>
<CopyLocalLockFileAssemblies>true</CopyLocalLockFileAssemblies>
</PropertyGroup>
<ItemGroup>
<PackageReference Include="DocumentFormat.OpenXml" Version="2.14.0" />
</ItemGroup>
</Project>
I was then finally able to debug into whichever method I wanted in the class library.
In my .csproj file, i have the following written:
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<OutputType>Exe</OutputType>
<TargetFramework>netcoreapp3.1</TargetFramework>
<RootNamespace>SCR_Number_Generator</RootNamespace>
<RuntimeIdentifiers>win-x64;osx-x64</RuntimeIdentifiers>
</PropertyGroup>
</Project>
This is because I want to build a single/self contained executable for my app. I run the following command: dotnet publish -p:PublishSingleFile=true --no-self-contained and it gives the following error:
/usr/local/share/dotnet/sdk/6.0.302/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.Publish.targets(102,5): error NETSDK1097: It is not supported to publish an application to a single-file without specifying a RuntimeIdentifier. You must either specify a RuntimeIdentifier or set PublishSingleFile to false. [/Users/lincolnmuller/SCR-Random-Number/SCR-Number-Generator/SCR-Number-Generator.csproj]
When i do a single RuntimeIdentifier, it detects it. But it doesn't detect RuntimeIdentifiers. How do I fix this?
Visual Studio 2022
C# WPF Project
I want to distribute a single .exe file, without requiring the target computer to install .NET 6.0 runtimes.
I can only find solutions for C/C++ code generation in the project's property window, but what I see in VS 2022 is totally different and there's no settings for static linking.
How to Deploy a single-file .NET 6 WPF app:
Right-click on the WPF application project in the Solution Explorer and select Edit Project File
Add the following line to the <PropertyGroup> element in the .csproj file:
<IncludeNativeLibrariesForSelfExtract>true</IncludeNativeLibrariesForSelfExtract>
Right-click on the project in the Solution Explorer and select Publish
Set the Deployment mode to Self-contained under the Target Runtime settings
Select win-* as the Target runtime
Check the Produce single file option under File publish options
Click on Save and then on Publish
Copy the contents of the Target location to the target machine and run the app`

I am using VS 2019 and .Net 5 to build a simple console application. I wanted to share this app with a friend so I tried to publish it as a single file but I keep getting some extra DLLs that the executable needs to run correctly.
Edit: Switching this project to .net core 3.1 works as expected I am able to export a single Exe file without any required DLLs.
Dotnet Cli:
dotnet publish -c Release -o publish -p:PublishReadyToRun=true -p:PublishSingleFile=true -p:PublishTrimmed=true --self-contained true
Csproj:
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<OutputType>Exe</OutputType>
<TargetFramework>net5.0</TargetFramework>
<PublishSingleFile>true</PublishSingleFile>
<RuntimeIdentifier>win-x64</RuntimeIdentifier>

Its known issue that described here: https://github.com/dotnet/runtime/issues/36590
And new dev experience provided here: https://github.com/dotnet/designs/blob/main/accepted/2020/single-file/design.md#user-experience
So in your case you need use p:IncludeNativeLibrariesForSelfExtract=true additionaly.
Full command:
dotnet publish -c Release -o publish -p:PublishReadyToRun=true -p:PublishSingleFile=true -p:PublishTrimmed=true --self-contained true -p:IncludeNativeLibrariesForSelfExtract=true
or include this flag in .csproj file
<PropertyGroup>
<OutputType>Exe</OutputType>
<TargetFramework>net5.0</TargetFramework>
<PublishSingleFile>true</PublishSingleFile>
<RuntimeIdentifier>win-x64</RuntimeIdentifier>
<PlatformTarget>x64</PlatformTarget>
<IncludeNativeLibrariesForSelfExtract>true</IncludeNativeLibrariesForSelfExtract>
</PropertyGroup>
I just started a new project in VS Code (C#, .NET Core). Anyways, I want to be able to copy files from within my project directory to the output directory like I can in visual studio. But I also want to copy specific files depending on whether or not I'm building for 32 or 64 bit.
I've looked around but so far all I've learnt how to do is copy files regardless of my build configurations.
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<OutputType>Exe</OutputType>
<TargetFramework>netcoreapp2.1</TargetFramework>
</PropertyGroup>
<ItemGroup Condition="'$(RuntimeIdentifier)' == 'win-x86' Or '$(RuntimeIdentifier)' == 'win-x64'">
<None Update="foo.txt">
<CopyToOutputDirectory>Always</CopyToOutputDirectory>
</None>
</ItemGroup>
<ItemGroup Condition="'$(RuntimeIdentifier)' == 'win-x64'">
<None Update="foo.xml">
<CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
</None>
</ItemGroup>
</Project>
Steps:
Create a console app by running dotnet new console
Add foo.txt and foo.xml to the project folder.
Edit the .csproj file as above.
Build the project with multiple configurations.
dotnet build -c Release -r win-x86
foo.xml is copied only for a x-64 build whereas foo.txt is copied for both RID's
