Assembly parameter value for nswag aspnetcore2swagger command

I’m trying to use latest version of nswag (11.18.7 at the moment) from msbuild in asp.net core project (netcoreapp2.1) and aspnetcore2swagger command just doesn’t work. Error is always System.IO.FileNotFoundException no matter if I use full assembly path, relative path from project folder or just assembly name. I’m using it the way it is recommended in the documentation for .NET Core projects:

  <Target Name="NSwag" AfterTargets="Build">
    <Copy SourceFiles="@(ReferencePath)" DestinationFolder="$(OutDir)References" />
    <Message Importance="high" Text="Run '$(NSwagExe_Core21) aspnetcore2swagger /assembly:$(OutDir)$(AssemblyName).dll'" />
    <Exec Command="$(NSwagExe_Core21) aspnetcore2swagger /assembly:$(OutDir)$(AssemblyName).dll" />
    <RemoveDir Directories="$(OutDir)References" />
  </Target>

If I just replace aspnetcore2swagger command with webapi2swagger without making any other changes - it works perfectly.

I’ve tried debugging this issue, but I got stuck at IsolatedCommandBase.RunIsolatedAsync, unable to step into the Task.Run code.

But I also found a satisfactory workaround by using $(OutDir) to set the working directory instead of passing it to /assembly::

<Exec Command="$(NSwagExe_Core21) aspnetcore2swagger /assembly:$(TargetFileName) /output:build-artifacts/swagger.json" WorkingDirectory="$(OutDir)" />

• you shouldnt use webapi2swagger as this generator will not be supported eventually… we need to get aspnetcore2swagger running in all scenarios… please try aspnetcore2swagger with a project (and not assembly) + nobuild true when running from csproj
