currently when I install a nuget package inside .net standard app i can only able update the PackageReference indie the csproj <PackageReference Include="sip-si" Version="4.0.10" /> rest of all the referance are not able to update the updated version inside the same csproj file ex <Target Name="CopyReferenceDll" AfterTargets="Build"> <Copy SourceFiles="..\..\_Common\packages\sip-si.4.0.9\lib\netstandard2.0\Wrapper.dll" DestinationFolder="$(TargetDir)" /> <Copy SourceFiles="..\..\_Common\packages\sip-si.4.0.9\lib\netstandard2.0\Wrapper.pdb" DestinationFolder="$(TargetDir)" /> </Target> <Import Project="..\..\_Common\packages\sip-si.4.0.9\build\sip5-simu-dsi.targets" Condition="Exists('..\..\_Common\packages\sip-si.4.0.9\build\sip5-simu-dsi.targets')" /> and it gives an error after installation and i need to update them manually is there any way to modify the sip-si. nuspec file so after installation of the nuget pack the target section also will get updated with the particular version and I saw it is not possible to run a powershell script during installation of a nuget package . could some body help me what is the best way to handle this ,I mean how to update the .csproj file during installation.

Hi @Aditya Dalai , Unfortunately, there isn't a direct way to automatically update these file paths when you update your NuGet package version, as NuGet doesn't support running custom scripts during package installation in .NET Core and .NET Standard projects because of security reasons. However, you could try below ways: 1)Instead of hardcoding the version number in your .csproj file, you could use an MSBuild property. This allows you to define the version in one place and use that property throughout your project file. <PropertyGroup> <SipSiVersion>4.0.10</SipSiVersion> </PropertyGroup> <PackageReference Include="sip-si" Version="$(SipSiVersion)" /> <Target Name="CopyReferenceDll" AfterTargets="Build"> <Copy SourceFiles="..\..\_Common\packages\sip-si.$(SipSiVersion)\lib\netstandard2.0\Wrapper.dll" DestinationFolder="$(TargetDir)" /> </Target> 2)For the DLL and PDB files, you can use wildcard versioning in the file path if your package versions follow a consistent naming convention. <Copy SourceFiles="..\..\_Common\packages\sip-si.*\lib\netstandard2.0\Wrapper.dll" DestinationFolder="$(TargetDir)" /> 3)If you have control over the NuGet package ( sip-si ), you can include a .targets file within the package that contains the necessary MSBuild logic to copy the files and reference them correctly using the property. 4)Although NuGet doesn't allow running PowerShell scripts during package installation anymore, you could use a custom MSBuild target that runs after package restoration to update the references.

Hi @Aditya Dalai ,

Unfortunately, there isn't a direct way to automatically update these file paths when you update your NuGet package version, as NuGet doesn't support running custom scripts during package installation in .NET Core and .NET Standard projects because of security reasons.

However, you could try below ways:

1)Instead of hardcoding the version number in your .csproj file, you could use an MSBuild property. This allows you to define the version in one place and use that property throughout your project file.

<PropertyGroup> <SipSiVersion>4.0.10</SipSiVersion> </PropertyGroup> <PackageReference Include="sip-si" Version="$(SipSiVersion)" /> <Target Name="CopyReferenceDll" AfterTargets="Build"> <Copy SourceFiles="..\..\_Common\packages\sip-si.$(SipSiVersion)\lib\netstandard2.0\Wrapper.dll" DestinationFolder="$(TargetDir)" /> </Target>

2)For the DLL and PDB files, you can use wildcard versioning in the file path if your package versions follow a consistent naming convention.

<Copy SourceFiles="..\..\_Common\packages\sip-si.*\lib\netstandard2.0\Wrapper.dll" DestinationFolder="$(TargetDir)" />

3)If you have control over the NuGet package (sip-si), you can include a .targets file within the package that contains the necessary MSBuild logic to copy the files and reference them correctly using the property.

4)Although NuGet doesn't allow running PowerShell scripts during package installation anymore, you could use a custom MSBuild target that runs after package restoration to update the references.

thank you @Jalpa Panchal-MSFT , for the response ,

I am facing once more issue with respect to the above response

<PropertyGroup> <SipSiVersion>4.0.10</SipSiVersion> </PropertyGroup> <ItemGroup> <PackageReference Include="sip-si" Version="$(SipSiVersion)" /> </ItemGroup> <Target Name="CopyReferenceDll" AfterTargets="Build"> <Copy SourceFiles="..\..\_Common\packages\sip-si.$(SipSiVersion)\lib\netstandard2.0\Wrapper.dll" DestinationFolder="$(TargetDir)" /> </Target>

while updating from sip-si version from 4.0.10 to 4.0.11 the I am able to see the packageReference got change but the <SipSiVersion>4.0.10</SipSiVersion> didn't get change.

after updating the package from 4.0.10 to 4.0.11 the .csproj comes like this

<PropertyGroup> <SipSiVersion>4.0.10</SipSiVersion> </PropertyGroup> <ItemGroup> <PackageReference Include="sip-si" Version="4.0.11" /> </ItemGroup> <Target Name="CopyReferenceDll" AfterTargets="Build"> <Copy SourceFiles="..\..\_Common\packages\sip-si.$(SipSiVersion)\lib\netstandard2.0\Wrapper.dll" DestinationFolder="$(TargetDir)" /> </Target>

The issue you are facing is the by designed behavior of the NuGet and MSBuild.The <PackageReference> version is updated because that's what NuGet is designed to manage. However, NuGet does not update other properties within your .csproj file like <SipSiVersion> because it does not have the capability to manage custom MSBuild properties.

To keep your version synchronized, you could try below options:

1)Manually update the <SipSiVersion> property whenever you update the NuGet package.

2)If you are using SDK-style projects and a recent version of Visual Studio, you can use the Central Package Version Management feature. This allows you to define package versions in one place a Directory.Packages.props file, and those versions are used for all projects in the solution.

Hi @Jalpa Panchal-MSFT

it was really helpful one approach you have mention Although NuGet doesn't allow running PowerShell scripts during package installation anymore, you could use a custom MSBuild target that runs after package restoration to update the references. so can we write a power shell script and try to execute inside the targets files some thing like this bellow

<Project>  <Target Name="UpdateReferences" AfterTargets="Restore">   <Exec Command="powershell.exe -ExecutionPolicy Bypass -File install.ps1" /> </Target>  </Project>

install.ps1 will contain the logic to update the folder path form 4.0.9 to 4.0.10 ? will it work if yes could you please give me some document to follow ?

and If you have control over the NuGet package (sip-si), you can include a .targets file within the package that contains the necessary MSBuild logic to copy the files and reference them correctly using the property.

yes I have the control over the nuget package (so is it possible to modify .targets so where ever this package is getting install it can update the path as per the latest version of the package or the specific tag <SipSiVersion>4.0.10</SipSiVersion> as per the latest version ) .

When creating the NuGet package, include a .targets file in the build or buildMultiTargeting folder of your NuGet package. This .targets file should contain the necessary MSBuild logic to copy files and reference them correctly.

Instead of relying on PowerShell scripts, it's better to use pure MSBuild tasks within the .targets file to modify the file paths. You can use MSBuild properties and tasks to find and replace strings in files, update item metadata, etc.

Here is sample code of what your .targets file could look like:

 <Project> <PropertyGroup>  <SipSiVersion>4.0.10</SipSiVersion> </PropertyGroup>  <Target Name="CopyWrapperDll" AfterTargets="Build"> <Copy SourceFiles="$(MSBuildThisFileDirectory)..\lib\netstandard2.0\Wrapper.dll" DestinationFolder="$(TargetDir)" /> <Copy SourceFiles="$(MSBuildThisFileDirectory)..\lib\netstandard2.0\Wrapper.pdb" DestinationFolder="$(TargetDir)" /> </Target> </Project>

Regarding updating the <SipSiVersion> tag automatically, you would typically handle this outside of MSBuild with a script that runs as part of your release process. This script would update the version in your .csproj file and regenerate the .nuspec and .targets files as needed before packing. This way, when you pack your NuGet package, it contains the correct version number.

If you're looking for more detailed documentation on how to create and work with .targets files, here is the document https://learn.microsoft.com/en-us/visualstudio/msbuild/msbuild-targets?view=vs-2022. For creating NuGet packages that include these targets, check the https://docs.microsoft.com/en-us/nuget/create-packages/creating-a-package
