Issuesseeninthisregressionincludeanincreasedrateofslow/failedDNSrequests,andFabricDNScrashingmorethanusual. This release includes an additional fix for a memory leak in very specific scenarios when using remoting V2 and creating and destroying services dynamically. Service Fabric 7.2 and higher runtime drops support for .NET core Service Fabric apps running with .NET core 2.2 runtime. .NET core runtime 2.2 is out of support from Dec 2019. Service Fabric runtime will not install .NET core runtime 2.2 as part of its dependency. Customers should upgrade their .NET 2.2 runtime SF apps to the next .NET core LTS version 3.1. .NET core runtime LTS 2.1 runtime will go out of support from Aug 21, 2021. Service Fabric releases after that date will drop support for Service Fabric apps running with .NET core 2.1 runtime. Service Fabric .NET SDK will take a dependency on .Net runtime 3.* features to support Service Fabric .NET core apps. This has no impact on Service Fabric .NET Framework SDK. .NET 5 apps are currently not supported, support for .NET 5 applications will be added in the Service Fabric 8.0 release. We will be deprecating the latest tag for .The new scheme for containers will substitute the current naming scheme latest to be replaced with an OS-targeted latest set to explicitly identify the base OS for latest SF releases: mcr.microsoft.com/service-fabric/onebox:u16 mcr.microsoft.com/service-fabric/onebox:u18 The default action of deleting uploaded application package is changed. If the application package is registered successfully, the uploaded application package is deleted by default. Before this default action changes, the uploaded application package was deleted either by calling to or by using ApplicationPackageCleanupPolicy parameter explicitly with Service Fabric 7.2 will become the baseline release for future development of image validation. When the feature is activated in future version e.g., Service Fabric 7.3, the cluster is not desired to rolled back down to 7.1 or lower. The version 7.2 is the baseline to which the cluster can downgrade. | Versions | IssueType | Description | Resolution | |-|-|-|-| | Windows 7.2.433.9590 | Bug |FabricDNS regression introduced in 7.2.|Brief desc: FabricDNS would not behave as expected after upgrading to 7.2.<br> Impact: Issuesseeninthisregressionincludeanincreasedrateofslow/failedDNSrequests,andFabricDNScrashingmorethanusual. <br> Workaround: Upgrade to 7.2 CU2/CU3. <br> Fix: This regression has been fixed as part the CU2 release.
