I'm using a NuGet package in the project. Is there a way to isolate or ignore that NuGet package and use another NuGet package using a compile switch or Macro?
Purpose: This NuGet Package is licensed per developer, So the intent is to disconnect it during the development from other developers.
I have looked into myproject.csproj
...
<ItemGroup>
<PackageReference Include="nugetPackage2Exclude" Version="1.0.0.0">
<ExcludeAssets>none</ExcludeAssets>
</PackageReference>
...
But, I could not make it work using a compile switch or macro.
CodePudding user response:
After a lot of tinkering. This is the final solution that turned out to satisfy all my requirements. It is a bit long and I have added all the findings relevant to this question.
Before I get into implementation, this is my setup #(.NET 6.0, C# 10, WPF Project, VS2022)
Steps involved!
- Declaration of a compile switch
- Prebuild conditional switch for compiling/ignoring the Nuget Package
- Context switch in the XAML file.
- Compile switches to isolate the package in the C# file.
Step1: Declaration of a compile switch (NUGET_ENABLE)
Project -> Proprties -> Conditional Compilation Symbols
$(DefineConstants);NUGET_ENABLE
(Note: A value cannot be assigned to the NUGET_ENABLE, The NUGET_ENABLE has to be renamed or removed for Removing this NuGet Usage.)
Step2: Prebuild conditional switch for compiling/ignoring the Nuget Package
Open the myproject.csproj (Project file). Use a regex expression to find the specific compile switch from $(DefineConstants), If NUGET_ENABLE exists compile the NuGet package.
(Reference: MS Docs)
<Choose>
<When Condition="$([System.Text.RegularExpressions.Regex]::IsMatch($(DefineConstants), '^(.*;)*NUGET_ENABLE(;.*)*$'))">
<!-- When NUGET_ENABLE is defined. -->
<ItemGroup>
<PackageReference Include="nugetPackage2Exclude" Version=""/>
</ItemGroup>
</When>
</Choose>
Step3: Context switch in the XAML file
(Reference: this question)
Step3a: Edit the assembly file to add a XAML Switch
#if NUGET_ENABLE
[assembly: XmlnsDefinition("nuget_enable", "NameSpace")]
#endif // NUGET_ENABLE
Step3b: Add the XAML file headers
...
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:nuget="http://schemas.nugetPackage2Exclude.etc/"
xmlns:nugetEnabled="nuget_enable"
...
mc:Ignorable="d nuget" // d is optional!
...
Step3c: Add the XAML context switch
<mc:AlternateContent>
<mc:Choice Requires="nugetEnabled">
<!--<code calling the nuget>-->
</mc:Choice>
<mc:Fallback>
</mc:Fallback>
</mc:AlternateContent>
Step4:Compile switches to isolate the package in the C# file.
#if NUGET_ENABLE
// Code
#endif
