Hi guys I trying to use SimpleBase.Dll from GitHub - ssg/SimpleBase: .NET library for encoding/decoding Base16, Base32, Base58 and Base85. . i Download the package, rename the package as a ZIP file and copy the DLL to the plugins folder on my project. but when i restart i got this error:

Error: Could not load signature of SimpleBase.Base16:GetSafeByteCountForDecoding due to: Could not resolve type with token 01000019 (from typeref, class/assembly System.ReadOnlySpan`1, netstandard, Version=2.1.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51) assembly:netstandard, Version=2.1.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51 type:System.ReadOnlySpan`1 member:(null) signature:<none>

Any clue ??
thanks in advance

Looks like that DLL is using ReadOnlySpan type. That type has been added in .NET Standard 2.1, whereas Unity only supports .NET Standard 2.0. A workaround could include recompiling the DLL for .NET Standard 2.0 or .NET Framework 4.7.1.

Hi, Did you manage to recompile the dll for net 4.7.1? I’m having the same issue when trying to use ipfs net client.
