ModPhuserEx Got an error when trying to Protect .NETStandard 2.0 library.

[ERROR] Failed to resolve dependency of 'My.dll'.
Exception: dnlib.DotNet.AssemblyResolveException: Could not resolve assembly: netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51
　　at dnlib.DotNet.Extensions.ResolveThrow(IAssemblyResolver self, IAssembly assembly, ModuleDef sourceModule) in C:\projects\modphuserex\dnlib\src\DotNet\IAssemblyResolver.cs:line 113
　　at Confuser.Core.ConfuserEngine.Inspection(ConfuserContext context) in C:\projects\modphuserex\Confuser.Core\ConfuserEngine.cs:line 264

I'm caught in a dilemma: To use Obfuscation attribute we need .NET Standard 2.0. It is not supported in .NET Stardard 1.6 or earlier. But when my project upgraded to .NET Standard 2.0, we will not be able to protect my dlls with ModPhuserEx.

I'm trying to build ModPhuserEx on .NET Standard 2.0 and hope it can be done.

Just a clarification: MPX/ConfuserEx run on. NET Framework/Mono. They never themselves ran on .NET Core or were .NET Standard-compatiable; this is mainly due to dnlib choosing to stay on .NETFx. However the project does support .NET standard/core libraries.

I'll take a closer look later; for now could you please confirm that you set probe paths like described in the wiki? Thanks.

Yes. I have confirmed that. See https://github.com/0xFireball/ModPhuserEx/issues/3#issuecomment-324321458 .

BTW, I found a possibly related post on SO: 'Could not load file or assembly 'netstandard, Version=2.0.0.0, …'. Reference assemblies should not be loaded for execution.

After adding some more probePath to the project file, the original Could not resolve assembly: netstandard error is gone.

<probePath>W:\VS2017\MyApp\bin\Release\PublishOutput</probePath>
<probePath>W:\VS2017\MyApp\bin\Release\PublishOutput\runtimes\win\lib\netcoreapp2.0</probePath>
<probePath>C:\Program Files\dotnet\sdk\2.0.0\Sdks\Microsoft.NET.Sdk\tools\net46</probePath>
<probePath>C:\Program Files\dotnet\sdk\2.0.0\Microsoft\Microsoft.NET.Build.Extensions\net461\lib</probePath>

But new errors occurred:

I think this is specific to my project and still trying to find a solution.

@zwcloud have you eventually resolved this problem?

@zwcloud have you eventually resolved this problem?

No, I gave up. I was just trying ModPhuserEx.
