Nswag: System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.AspNetCore.Mvc.ViewFeatures

[kalkusa]

When loading .NET Assembly Path on Web API Assembly tab I got the following error:

I have .NET core instlaled:

PS C:\Windows\system32> dotnet --version
2.1.4

System: Windows 10. Assembly's framework:L .NET Core 2.0.

You have to dotnet publish before loading the DLL because otherwise some framework assemblies are missing...

I've published. First of all - should I add just Web API assembly to ".NET Assembly Paths" or all from the publish directory? Another thing the missing assembly (Microsoft.AspNetCore.Mvc.ViewFeatures) is not present in publish directory...

v11.14.0:

We improved the assembly loader (mainly for .NET Core) so that it runs in a more isolated space and the loaded DLLs should better match the requested versions. Please test this with your projects to ensure that we didnt introduce regressions.

Important if you have DLL loading problems:

• Check that the DLL in question is available in the output directory (where the selected assembly is located) or in ReferencePaths
• Check that you selected the correct runtime: Either in NSwagStudio UI, as /runtime parameter in the NPM CLI or execute the correct exe binary

How can I fix this for .NET Core 3.1?
