Could not load System.Text.Json 7.0.0.0

[rametta]

Description

Hello, starting a new project and trying to use SwaggerProvider and following the getting started docs I get an error of:

The type provider 'SwaggerProvider.OpenApiClientTypeProvider' reported an error: Could not load file or assembly 'System.Text.Json, Version=7.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'. Could not find or load a specific file. (0x80131621)

when I try to init the first provider.

Repro steps

Start a new project, install SwaggerProvider 2.0.0-beta7. Follow the getting started docs, see error

This happens with both SwaggerClientProvider and OpenApiClientProvider

here is my fsproj file

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

    <PropertyGroup>
        <TargetFramework>net6.0</TargetFramework>

        <IsPackable>false</IsPackable>
        <GenerateProgramFile>false</GenerateProgramFile>
    </PropertyGroup>

    <ItemGroup>
        <Compile Include="Tests.fs" />
        <Compile Include="Program.fs" />
    </ItemGroup>

    <ItemGroup>
        <PackageReference Include="Microsoft.NET.Test.Sdk" Version="16.11.0" />
        <PackageReference Include="SwaggerProvider" Version="2.0.0-beta7" />
        <PackageReference Include="xunit" Version="2.4.1" />
        <PackageReference Include="xunit.runner.visualstudio" Version="2.4.3">
            <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
            <PrivateAssets>all</PrivateAssets>
        </PackageReference>
        <PackageReference Include="coverlet.collector" Version="3.1.0">
            <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
            <PrivateAssets>all</PrivateAssets>
        </PackageReference>
    </ItemGroup>

</Project>

Expected behavior

No error for missing dependencies

Actual behavior

Error showing that missing dependency and when explicitly installing that dependency the error still does not go away

Known workarounds

None that I know of, I can not get it to work.

Can you please try 2.0.0-beta6?

[rametta]

Yes that does seem to help, thank you

Although in Rider I keep getting error messages like this when trying to call an endpoint:

The type 'MyModule.MyProvider.Client' is not compatible with the type 'MyModule.MyProvider.Client'

Any ideas why there might be a type mismatch there?

[sergey-tihon]

It is FSI/F# Interactive or compiled binary?

[rametta]

Compiled

"The type X is not compatible with the type X" is typically that you defined type X in 2 different source-code paths, and A and B and then you make a function the takes A as parameter and you try to plug-in the type B when calling the function.

[sergey-tihon]

Do you think that it is the caching issue of ProvidedTypes? https://github.com/fsprojects/SwaggerProvider/blob/master/src/SwaggerProvider.DesignTime/Caching.fs

[Thorium]

I don't: As far as I know TypeProviders, I rather think (as a very wild guess, I've not seen this issue) that some source-file could be "included as a link" and thus defined both in design-time and runtime as a separate type. (The other option would be that it's loaded separately twice for different target frameworks which are actually compatible.) If that's the case, then the type should be probably defined in runtime only and referenced from runtime by the design-time.
