Source generator

[bastiennoel93]

Hello,

When I open my visual studio, files are generated.
But when I delete them, after opening, even if I restore or rebuild, the files are not generated.
I have to close and open my visual studio for them to regenerate.

Have you had this problem?

@bastiennoel93 Thanks for taking the time to report this.

There was a known issue in a previous release of Refitter where the Source Generator stopped working due to a bad dependency update. The source generator in lastest stable version, v1.1.3 works fine after I just tested it right now

I created an empty .NET console app and added the Refit and Refitter.SourceGenerator package references. The csproj looks like this

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net8.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Refit" Version="7.1.2" />
    <PackageReference Include="Refitter.SourceGenerator" Version="1.1.3">
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
      <PrivateAssets>all</PrivateAssets>
    </PackageReference>
  </ItemGroup>

</Project>

I added a .refitter file that points to the Swagger Petstore v3 example. It looks like this

{
  "openApiPath": "https://petstore3.swagger.io/api/v3/openapi.json",
  "namespace": "Petstore"
}

When I build the project, I get the following, it generates a folder called Generated with a single file in it called petstore.g.cs

My working folder looks like this:

total 24
drwxr-xr-x  3 christianhelle  staff   96 Jul 23 16:37 Generated
-rw-r--r--  1 christianhelle  staff  105 Jul 23 16:28 Program.cs
-rw-r--r--  1 christianhelle  staff   99 Jul 23 16:32 petstore.refitter
-rw-r--r--  1 christianhelle  staff  582 Jul 23 16:34 refitter.sourcegen.sample.csproj

The issue appears in v1.1.2 and I updated the package in nuget.org to display it as deprecated

When I use v1.1.2 in a project like this

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net8.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Refit" Version="7.1.2" />
    <PackageReference Include="Refitter.SourceGenerator" Version="1.1.2">
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
      <PrivateAssets>all</PrivateAssets>
    </PackageReference>
  </ItemGroup>

</Project>

The build output is the following

MSBuild version 17.8.3+195e7f5a3 for .NET

@bastiennoel93 Sorry! I missed this detail in my previous responses. No, I don't think I have seen this before. One thing you could do to force re-generation is to shut down the build-server by calling dotnet build-server shutdown from the command line in the projects working folder

I spend most of my time in Rider which only triggers the source generator upon build. Visual Studio triggers the source generator by making changes to the .refitter file. I guess triggering the source generator based on file changes are better than something triggered by the build, but I just got use to it
