C# DataProtection兼容性网络框架和网络核心无效负载异常

我有两个项目，一个使用netcore，另一个使用netframework

如本节所述，数据保护密钥的共享

.netFramework

 public override void ConfigureServices(IServiceCollection services)
 {
        services.AddDataProtection()
            .SetApplicationName("company")
            .PersistKeysToFileSystem(new DirectoryInfo("c:\\keys"))
            .ProtectKeysWithDpapi();
 }

       //hello protected in net framework.
       var helloProtected = MachineKey.Protect(Encoding.UTF8.GetBytes("hello"),
            "testprotector");
        var base64HelloProtected = Convert.ToBase64String(helloProtected);

netCore先生

public void ConfigureServices(IServiceCollection services) 
{
    services.AddDataProtection()
            .SetApplicationName("company")
            .PersistKeysToFileSystem(new DirectoryInfo("c:\\keys"))
            .ProtectKeysWithDpapi();
}
        var bs64msg = //Here i put the protected payload from net framework.
        var msgUnprotected = _provider.CreateProtector("testprotector")
            .Unprotect(Convert.FromBase64String(bs64msg));

然后我得到一个无效的负载异常

有没有想过这一点？我遇到了类似的问题。
