Build failing: 'System.ReadOnlySpan'

[KazeEnji]

Hello,

I'm attempting to use Codeception against Rubeus and I'm running into this error:

Could not compile solution: Method not found: 'System.ReadOnlySpan1Microsoft.IO.Path.GetFileName(System.ReadOnlySpan1<Char>)'.

My research shows that this is due to a breaking change that happened with MSBuild at version 4.0.5 but I have the proper version installed per the github instructions: 3.9.0. I don't know what to change about it. I'm running Codeception with the debug switch and that doesn't seem to do anything either.

Sane here.

Unhandled Exception: System.MissingMethodException: Method not found: 'System.ReadOnlySpan`1<Char> Microsoft.IO.Path.GetFileName(System.ReadOnlySpan`1<Char>)'

A solution would be editing Codecepticon.exe.config in the folder where your exe is and updating assemblyBinding entry for System.Memory; increase the max version range to something to higher like 5.0.0.0:

    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.Memory" publicKeyToken="cc7b13ffcd2ddd51" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-5.0.0.0" newVersion="4.0.1.2" />
      </dependentAssembly>
    </assemblyBinding>
