System.IO.FileNotFoundException: Could not load file or assembly 'System.Runtime, Version=7.0.0.0 using code generator

Hi Amazing Mapster team,

I wanted to expose you the case that I have, with which I am currently stuck and I do not quite understand the reason.

I'm trying to implement Mapster using the benefits of the code generation.

Following the documentation provided, I created the dotnet-tools file, installed mapster.tool added the required code in csproj file, I've tried with and without AfterBuild but the final result is the same. (Below code using AfterBuild )

        <ItemGroup>
                <Generated Include="**\*.g.cs" />
    </ItemGroup>
    <Target Name="CleanGenerated">
        <Delete Files="@(Generated)" />
    </Target>

    <Target Name="Mapster" AfterTargets="AfterBuild">
        <Exec WorkingDirectory="$(ProjectDir)" Command="dotnet tool restore" />
        <Exec WorkingDirectory="$(ProjectDir)" Command="dotnet mapster model -a &quot;$(TargetDir)$(ProjectName).dll&quot; -n Xelit3.Benchmarks.Generated" />
        <Exec WorkingDirectory="$(ProjectDir)" Command="dotnet mapster extension -a &quot;$(TargetDir)$(ProjectName).dll&quot; -n Xelit3.Benchmarks.Generated" />
        <Exec WorkingDirectory="$(ProjectDir)" Command="dotnet mapster mapper -a &quot;$(TargetDir)$(ProjectName).dll&quot; -n Xelit3.Benchmarks.Generated" />
    </Target>   

At the end, I end up always with the same issue:

File name: 'System.Runtime, Version=7.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' System.IO.FileNotFoundException: Could not load file or assembly 'System.Runtime, Version=7.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. El sistema no puede encontrar el archivo especificado.

I'm using .NET7 console project, I tried using Mapster 7.3.0 and 7.4.0-pre05, both with similar result.

I also tried specifying namespace in the model, extension and maper exec commands, same result

I'm trying to use Fluent API flavour since the POC has the models in a different assembly, similar scenario of our real world projects.

I'm sure that I'm missing something, but with the information that I can extract from the output and the similar issues reported I'm not able to progress on it.

The entire code is available here to check it

Many thanks in advance for your support

I'm facing the same issue when I'm using dotnet 7

[stagep]

Was the Mapster.Tool installed using the pre-release version?

dotnet tool install Mapster.Tool --version 8.4.0-pre05

I am successfully using .Net 7 with Mapster 7.4.0-pre05 and Mapster.Tool 8.4.0-pre05.

That's correct @stagep. @Xelit3 I cloned your repo and verified that upgrading to Mapster.Tool version 8.4.0-pre06 fixes the problem.

Sorry for the delay replying it, I left it on hold for a couple of weeks.

Yes it worked once the Mapster.Tool was installed with the pre-release version (I tried with 8.4.0-pre05 at leastand it worked perfectly fine)

Many thanks for the support!
