❔ Incremental source generator not called with docker

Hello, I have 2 projects (simplified): - one sandbox .net6 - one SourceGenerator .netStandard2.0 In my SourceGenerator, I have a class called RestServicesSourceGenerator like this

using Microsoft.CodeAnalysis;
using Microsoft.CodeAnalysis.CSharp.Syntax;

[Generator]
public sealed class RestServicesSourceGenerator
    : IIncrementalGenerator
{
    public RestServicesSourceGenerator()
    {
    }

    void IIncrementalGenerator.Initialize(IncrementalGeneratorInitializationContext context)
    {
        // processing code
    }
}

using Microsoft.CodeAnalysis;
using Microsoft.CodeAnalysis.CSharp.Syntax;

[Generator]
public sealed class RestServicesSourceGenerator
    : IIncrementalGenerator
{
    public RestServicesSourceGenerator()
    {
    }

    void IIncrementalGenerator.Initialize(IncrementalGeneratorInitializationContext context)
    {
        // processing code
    }
}

And in my sandbox project, I have a reference of my SourceGenerator

<ProjectReference Include="..\..\project.csproj" OutputItemType="Analyzer" ReferenceOutputAssembly="true" />

<ProjectReference Include="..\..\project.csproj" OutputItemType="Analyzer" ReferenceOutputAssembly="true" />

When i start building my sandbox (from VS or from command line dotnet build --no-incremental), the IIncrementalGenerator.Initialize is executed and i can see my generated files. When i start building from docker using this image mcr.microsoft.com/dotnet/sdk:6.0 nothing happens. 😭 When i start building from azure pipepline using vmImage: 'ubuntu-latest' it's work 😅 If someone have an idea 🥹 Deps are :

<PackageReference Update="Microsoft.CodeAnalysis.Analyzers" Version="3.3.4" />
<PackageReference Include="Microsoft.CodeAnalysis.CSharp.Workspaces" Version="4.5.0" PrivateAssets="all" />

<PackageReference Update="Microsoft.CodeAnalysis.Analyzers" Version="3.3.4" />
<PackageReference Include="Microsoft.CodeAnalysis.CSharp.Workspaces" Version="4.5.0" PrivateAssets="all" />

Your generator is referencing workspaces? Also, MS.CA 4.5 corresponds to VS 17.5. That is not the version in .NET 6

QzLOP•2y ago

My generator reference some abstract projects for helping to generate or carry some custom attribute. Microsoft.CodeAnalysis.CSharp.Workspaces 4.5.0 can be used for .net6 app & netstandard2.0

333fred•2y ago

So, that doesn't mean what you think it means First and foremost: you need to not depend on workspaces You can only depend on MS.CA and MS.CA.CSharp/VB Workspaces APIs are not available to generators Second, yes MS.CA 4.5 supports being run on .NET 6. However, you don't control what version of MS.CA is used The compiler is the thing that loads you, not the other way around So you need to not depend on a newer version of MS.CA that could load you The best way to determine this is to look at the .NET 6 SDK and see what version the dlls are (iirc they're going to be either 4.0 or 4.1) You could also have the project consuming the generator depend on Microsoft.Net.Compilers.Toolset 4.5.0, which will cause the project to be built with the 4.5 version of MS.CA. However, the generator still won't work in VS less than 17.5

Thanks, I downgraded Microsoft.CodeAnalysis.CSharp.Workspaces to 4.2.0 and Microsoft.CodeAnalysis.Analyzers to 3.3.3 and it seem to work

333fred•2y ago

You cannot use Workspaces You will, at some point, accidentally use an API that is not available to your generator and it will fail again You must use MS.CA.CSharp

i need this package Microsoft.CodeAnalysis.CSharp.Workspaces to reference IIncrementalGenerator

No, that comes from MS.CA MS.CA's packages are a series of layers. The generator base apis (such as IIncrementalGenerator) come from the base layer When you run a dotnet build, you have up to and including the MS.CA.CSharp and VB layers The Workspaces layer includes all of these, but more things Those more things do not exist and you will run into errors if you accidentally start depending on APIs in this layer

QzLOP•2y ago

Sorry, misreading. yeah i will try with this

        <PackageReference Include="Microsoft.CodeAnalysis.Common" Version="4.2.0" PrivateAssets="all"/>
        <PackageReference Include="Microsoft.CodeAnalysis.CSharp" Version="4.2.0" PrivateAssets="all"/>

333fred•2y ago

You don't need the first, the second includes it as a transitive dependency. Otherwise, looks good

QzLOP•2y ago

I was some error without the Common

QzLOP•2y ago

333fred•2y ago

Your tests are depending on the wrong version still

QzLOP•2y ago

it ask for version 3.8.0 but on this version IIncrementalGeneratordoesn't exist, i should use ISourceGenerator

QzLOP•2y ago

333fred•2y ago

What asks for 3.8.0?

QzLOP•2y ago

Microsoft.CodeAnalysis.CSharp.Workspaces ask for Microsoft.CodeAnalysis.CSharp to be on version 3.8

333fred•2y ago

Wat Why are you referencing this package?

QzLOP•2y ago

I have only Microsoft.CodeAnalysis.CSharp on my deps

333fred•2y ago

Then what did you mean by this?

QzLOP•2y ago

333fred•2y ago

Well, first, you're depending on the CodeRefactoring unit testing framework. Why? And CodeFix Are you writing codefixers or refactorings?

QzLOP•2y ago

Only SourceGenerator

333fred•2y ago

Then only reference that unit testing framework

QzLOP•2y ago

it's global file props, i need to refactor this parts 🙂

Source generator updates: incremental generators: Exploring .NET 6 ...

In this post I look at the updates to the source generator API in .NET 6, why the changes were made, and how to update your source generators to use them.

QzLOP•2y ago

this is why i used Microsoft.CodeAnalysis.CSharp.Workspaces

333fred•2y ago

Well, I can't help bad articles 🙂

QzLOP•2y ago

Hello, I'm still blocked with the Microsoft.CodeAnalysis.CSharp. I don't use Microsoft.CodeAnalysis.CSharp.Workspaces but CA.Csharp required Workspace on 3.8.0. I shouldn't add Workspace on reference.. but when i add it and run it from VS it's good If i build from docker with sdk7 it's also good but i can't run test because the dotnet 6 runtime isn't here If i build from docker with sdk6 it's going bad (can't build)

QzLOP•2y ago

https://github.com/dotnet/roslyn/blob/main/docs/wiki/NuGet-packages.md 4.3.1 is good with .net 6

CA.Csharp does not require Workspaces. I'm not sure what is going on with the testing framework here though. @sharwell, why is the generator testing framework bringing in workspaces and ruining the package references here?

sharwell•2y ago

The source generator references Microsoft.CodeAnalysis.CSharp. The test project needs to explicitly reference Microsoft.CodeAnalysis.Workspaces.CSharp of the same version.

QzLOP•2y ago

thanks you i have created a Dockerfile with sdk 6 & sdk7 and now it's work 😄

Was this issue resolved? If so, run /close - otherwise I will mark this as stale and this post will be archived until there is new activity.
