CosmosDB UUID issue

Hi,

I’m currently facing issue with UUID 04 representation in CosmosDB mongo API driver:

"Message": "GuidRepresentation Standard is only valid with subType UuidStandard, not with subType UuidLegacy.\r\nИмя параметра: guidRepresentation"

They said they added it to all regions: https://feedback.azure.com/forums/263030-azure-cosmos-db/suggestions/20206180-support-uuid-subtype-4

I just wonder how to make it work both MongoDB and CosmosDB with Standard UUID type?

Seems to me that only CSharpLegacy type will work for both. Any suggestions?

yeah it does. I’ve also removed the static constructor in the last version of the repo 😉

Thanks for the feedback, I’ll look into removing the static constructor. I have not tested this, but are you sure you cannot overwrite the GuidRepresentation in the constructor of your repository though?

    public class TestRepository : BaseMongoRepository, ITestRepository
    {
        public TestRepository(string connectionString, string databaseName) : base(connectionString, databaseName)
        {
              MongoDbContext.SetGuidRepresentation(MongoDB.Bson.GuidRepresentation.CSharpLegacy);
        }
    }

According to https://github.com/mongodb/mongo-csharp-driver/blob/master/src/MongoDB.Driver/MongoDefaults.cs, it should not cause issues:

        /// <summary>
        /// Gets or sets the representation to use for Guids (this is an alias for BsonDefaults.GuidRepresentation).
        /// </summary>
        public static GuidRepresentation GuidRepresentation
        {
            get { return BsonDefaults.GuidRepresentation; }
            set { BsonDefaults.GuidRepresentation = value; }
        }
