Kako otkloniti pogreške 'hostpolicy.dll' i 'singlefilehost.exe' u .NET 8.0.11

Ključne promjene u .NET Build Tools s 8.0.0 na 8.0.11

Nakon nadogradnje na .NET 8.0.11, izgradnja nekih mojih projekata nije uspjela...

1 Opis problema

Postavke projekta izgradnje sve su dobro funkcionirale negdje oko .NET 8.0.0. Kasnije, s nadogradnjom .NET runtimea na novije verzije .NET 8.0 i .NET 9.0 i nadogradnjom na Visual Studio, neki su projekti prestali raditi. Čini se da su uveli ključne promjene u alate za izradu. Logika je i dalje zdrava, a vrste izrade su iste, samo su se alati za izradu počeli ponašati malo drugačije. Potrebne su nove konfiguracije i skripte za izgradnju.

Mislim da mogu locirati promjenu u ponašanju negdje između (.NET Framework 8.0.0/.NET SDK 8.0.100) i (.NET Framework 8.0.11/.NET SDK 8.0.404). Ne svi, ali neke izgradnje projekta nisu uspjele.

1.1 Okoliš

Tipično okruženje na koje se ovaj članak odnosi je C#/VS2022.

.NET verzija 8.0.11 ili novija

I gradite tip projekta SelfContained ili SingleFile

1.2 Manifestacija problema

Dobivate pogreške/iznimke :

• Biblioteka 'hostpolicy.dll' potrebna za izvođenje aplikacije nije pronađena

• pogreška MSB4018: …. Nije moguće pronaći datoteku ….. singlefilehost.exe

  
  

 +++Error1,When running the application:++++++++++++++++++++ A fatal error was encountered. The library 'hostpolicy.dll' required to execute the application was not found in 'C:\Program Files\dotnet\'. Failed to run as a self-contained app. - The application was run as a self-contained app because 'C:\tmpNetBundle\BundleExample02_NET90\ConsoleApp2C\ SelfContained_SingleFile_win-x64\ConsoleApp2C.runtimeconfig.json' was not found. - If this should be a framework-dependent app, add the 'C:\tmpNetBundle\BundleExample02_NET90\ConsoleApp2C\ SelfContained_SingleFile_win-x64\ConsoleApp2C.runtimeconfig.json' file and specify the appropriate framework. PS C:\tmpNetBundle\BundleExample02_NET90\ConsoleApp2C\ SelfContained_SingleFile_win-x64> +++Error2,During build++++++++++++++++++++ error MSB4018: The "GenerateBundle" task failed unexpectedly. [C:\tmpNetBundle\BundleExample01_NET_8.0.0_SDK_8.0.100\ConsoleApp2\ConsoleApp2.csproj] error MSB4018: System.IO.FileNotFoundException: Could not find file 'C:\tmpNetBundle\BundleExample01_NET_8.0.0_SDK_8.0.100\ConsoleApp2\ obj\Release\net8.0-windows\win-x64\singlefilehost.exe'.

1.3 Uzrok problema i rješenje

Čini se da je oznaka <PublishSingleFile>true</PublishSingleFile> u projektnoj datoteci .csproj u nekim slučajevima prestala raditi. Nakon toga sam se oslanjao na tu zastavu u svojim skriptama za izgradnju. Nema problema, to možemo predvidjeti, baš kad znamo što očekivati.

Čini se da je proces izrade pozvao "dotnet public" iz .NET SDK 9.* za projekte koje sam gradio za .NET 8.* framework. Stoga sam odlučio upotrijebiti datoteku global.json da eksplicitno odredim koji SDK želim koristiti.

 // NET_8.0.0/SDK_8.0.100 // NOTE: These project settings all worked well somewhere around .NET 8.0.0. Later, with the upgrade of .NET runtime to later versions of .NET 8.0 and .NET 9.0 and an upgrade to Visual Studio, some of projects stopped working. It looks like they introduced breaking changes in the build tools. Logic is still sound and build types are the same, just the build tools started to behave a bit differently. A new build configurations and build scripts are needed. <!--ConsoleApp2C.csproj +++++++++++++++++++++++++++++++++++++--> <Project Sdk="Microsoft.NET.Sdk"> <PropertyGroup> <OutputType>Exe</OutputType> <TargetFramework>net8.0-windows</TargetFramework> <ImplicitUsings>enable</ImplicitUsings> <Nullable>enable</Nullable> <PlatformTarget>x64</PlatformTarget> <Platforms>AnyCPU;x64</Platforms> <RuntimeIdentifier>win-x64</RuntimeIdentifier> <DebugType>embedded</DebugType> <PublishSingleFile>true</PublishSingleFile> <PublishTrimmed>true</PublishTrimmed> <IsTrimmable>true</IsTrimmable> <SelfContained>true</SelfContained> <IncludeAllContentForSelfExtract>true</IncludeAllContentForSelfExtract> <EnableCompressionInSingleFile>true</EnableCompressionInSingleFile> </PropertyGroup> <ItemGroup> <ProjectReference Include="..\ClassLibrary1\ClassLibraryA.csproj" /> </ItemGroup> <Target Name="PostBuild" AfterTargets="PostBuildEvent"> <Exec Command="echo +++Post-Build+++++&#xD;&#xA; if $(ConfigurationName) == Debug ( &#xD;&#xA;echo +++++Debug+++++ &#xD;&#xA;) &#xD;&#xA;&#xD;&#xA; if $(ConfigurationName) == Release ( &#xD;&#xA; echo +++++SelfContained_SingleFile_win-x64.cmd+++++ &#xD;&#xA; call SelfContained_SingleFile_win-x64.cmd &#xD;&#xA; echo +++++SelfContained_SingleFile_win-x64_Trimmed.cmd+++++ &#xD;&#xA; call SelfContained_SingleFile_win-x64_Trimmed.cmd &#xD;&#xA;) " /> </Target> </Project> +++++Script: SelfContained_SingleFile_win-x64.cmd dotnet publish ConsoleApp2C.csproj --no-build --runtime win-x64 --configuration Release -p:PublishSingleFile=true -p:SelfContained=true -p:PublishReadyToRun=false -p:PublishTrimmed=false --output ./SelfContained_SingleFile_win-x64 +++++Script: SelfContained_SingleFile_win-x64_Trimmed.cmd dotnet publish ConsoleApp2C.csproj --no-build --runtime win-x64 --configuration Release -p:PublishSingleFile=true -p:SelfContained=true -p:PublishReadyToRun=false -p:PublishTrimmed=true --output ./SelfContained_SingleFile_win-x64_Trimmed
