如果 grain 使用主键扩展功能，则不能使用 UniqueKey.PrimaryKeyToGuid 的重载

Question

尝试用 orleans 编写一个 hello world 程序，但出现此异常。

我正在使用 .net 5

Microsoft.Orleans.CodeGeneration.MSBuild nuget 包

InvalidOperationException: This overload of UniqueKey.PrimaryKeyToGuid cannot be used if the grain 
   uses the primary key extension feature.
   at Orleans.Runtime.UniqueKey.ThrowIfHasKeyExt(String methodName)
   at Orleans.Runtime.UniqueKey.PrimaryKeyToGuid()
   at Orleans.Runtime.GrainId.GetPrimaryKey()



var result = await _clusterClient.GetGrain<IHelloWorldGrain>("leke").SayHelloToAsync(name);

public class HelloWorldGrain : Grain, IHelloWorldGrain
{
    private int _invocationCount = 0;

    public Task<string> SayHelloToAsync(string name)
    {
         return Task.FromResult($"Hello {name} from {this.GetPrimaryKey()} - I have said hello {_invocationCount++} times.");
    }
}


public interface IHelloWorldGrain: IGrainWithStringKey
{
    Task<string> SayHelloToAsync(string name);enter code here
}

Answer 1

这个{this.GetPrimaryKey()}应该改成{this.GetPrimaryKeyAsString()}
