NSwag.MSBuild from Visual Studio 2017 .NET Core project

[jdcrutchley]

I've tried adding the following to my .csproj file from a .NET Core project in Visual Studio 2017:

<Target Name="GenerateSwagger" AfterTargets="Build"> <Exec Command="$(NSwagExe) webapi2swagger /assembly:$(OutDir)\$(AssemblyName).dll /output:testswagger.json" /> </Target>

When I run the build, I get this:

System.AggregateException: One or more errors occurred. ---> System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.AspNetCore.Authentication, Version=1.1.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60' or one of its dependencies. The system cannot find the file specified.

It seems the tool doesn't know where to find the DLLs for referenced NuGet packages. Am I missing some config?

Run "dotnet publish" so that all required dlls are in the output dir

Thank you. That helped. I'm now getting

Could not load file or assembly 'System.Security.Claims, Version=4.0.1.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

I've added $(PublishOutput)\refs to the /referencePaths option, so it's looking where System.Security.Claims is, but my project actually references version 4.3.0 of that assembly - which is what's in that directory - so not sure why it's looking for 4.0.1.0. I'll close this for now while I try to figure out the versioning problem.

For others with a similar issue, my solution in asp.net core with a netcoreapp1.1 target was the following

  <Target Name="GenerateSwagger" AfterTargets="Build">
    <Exec Command="$(NSwagExe) webapi2swagger /assembly:$(OutDir)\$(AssemblyName).dll /ReferencePaths:%UserProfile%\.nuget\packages /output:$(OutDir)\storage.swagger.generated.json" />
  </Target>

I've added the nuget chache folder to ReferencePaths

@RSuter dotnet publish didn't work for me with an .net core app 2,

dotnet publish "C:\Folder\Mysolution.sln" --configuration Release
NSwag.exe webapi2swagger /assembly:"C:\Folder\bin\Release\netcoreapp2.0\publish\Mysolution.dll" /output:swagger.json

System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Extensions.DependencyInjection.Abstractions, Version=2.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60' or one of its dependencies. The system cannot find the file specified.

@bqstony what path do you use in your build server?

Use the correct runtime:

Eg NSwagExe_Core11
