Microsoft Dynamics 365插件错误:您不能以与当前事务上已经设置的隔离级别不同的隔离级别启动交易

Question

我正在绑在使用Country2名称的自定义实体，通过在C＃中为Microsoft Dynamics 365 CRM编写插件。我正在以这种方式尝试;

// Create the custom entity.
                    CreateEntityRequest createrequest = new CreateEntityRequest
                    {
                        //Define the entity
                        Entity = new EntityMetadata
                        {
                            SchemaName = "Country2",
                            DisplayName = new Label("Country2", _languageCode),
                            DisplayCollectionName = new Label("Countries2", _languageCode),
                            Description = new Label("An entity to store information about cities.", 1033),
                            OwnershipType = OwnershipTypes.UserOwned,
                            IsActivity = false,
                        },
                        // Define the primary attribute for the entity
                        PrimaryAttribute = new StringAttributeMetadata
                        {
                            SchemaName = "new_countryname",
                            RequiredLevel = new AttributeRequiredLevelManagedProperty(AttributeRequiredLevel.None),
                            MaxLength = 100,
                            FormatName = StringFormatName.Text,
                            DisplayName = new Label("Country Name", _languageCode),
                            Description = new Label("The primary attribute for the Country entity.", _languageCode)
                        }
                    };
                    service.Execute(createrequest);
                    //Entity must be published
                    // Add few attributes to the custom activity entity.
                    CreateAttributeRequest fontFamilyAttributeRequest = new CreateAttributeRequest
                        {
                            EntityName = "Country2",
                            Attribute = new StringAttributeMetadata
                            {
                                SchemaName = prefix + "fontfamily",
                                DisplayName = new Label("Font Family", _languageCode),
                                MaxLength = 100
                            }
                        };
                    CreateAttributeResponse fontFamilyAttributeResponse =
                        (CreateAttributeResponse)service.Execute(
                        fontFamilyAttributeRequest);
                    CreateAttributeRequest fontColorAttributeRequest =
                        new CreateAttributeRequest
                        {
                            EntityName = "Country2",
                            Attribute = new StringAttributeMetadata
                            {
                                SchemaName = prefix + "fontcolor",
                                DisplayName = new Label("Font Color", _languageCode),
                                MaxLength = 50
                            }
                        };
                    CreateAttributeResponse fontColorAttributeResponse =
                        (CreateAttributeResponse)service.Execute(
                        fontColorAttributeRequest);
                    CreateAttributeRequest fontSizeAttributeRequest =
                        new CreateAttributeRequest
                        {
                            EntityName = "Country2",
                            Attribute = new IntegerAttributeMetadata
                            {
                                SchemaName = prefix + "fontSize",
                                DisplayName = new Label("Font Size", _languageCode)
                            }
                        };
                    CreateAttributeResponse fontSizeAttributeResponse =
                        (CreateAttributeResponse)service.Execute(
                        fontSizeAttributeRequest);
                    throw new InvalidPluginExecutionException("The Country custom entity has been created.");

在上面的代码中，我尝试首先制作new entity，然后尝试设置PrimaryAttribute，最后CreateAttributeRequest。

，但提示了;

的错误

您不能以与当前事务上已经设置的不同隔离级别启动交易。 这里有什么错吗？

不确定没有自定义前缀的实体可以创建实体。现在您的实体是" country2"，我将其更改为" new_country2"您的代码非常紧密地遵循在线提供的示例https://msdn.microsoft.com/en-us/library/gg509014.aspx

尝试将其切换到在线上，以查看该文章中是否使用相同名称创建实体/属性。
