New Breaking Changes

Angular now compiles with Ivy by default. See Ivy compatibility section.

Typescript 3.4 and 3.5 are no longer supported. Please update to Typescript 3.6.

tslib is now listed as a peer dependency rather than a direct dependency. Users not using the CLI will need to manually install tslib via yarn add tslib or npm install tslib --save. 

Today, we are releasing the 3.4.3 RTM version of the NuGet Visual Studio 2015 extension and the Windows x86 commandline executable. We continue to heavily invest in improving the quality of NuGet scenarios in Visual Studio and commandline. The complete list of issues fixed in this version is available on GitHub. In this post, we will review the important changes in 3.4.3 release. 

• TLS 1.0: The request was aborted: Could not create SSL/TLS secure channel.
• Task List with filter set to Entire Solution doesnt display tasks/todos when the file is closed.
• Fatal error C1001: An internal error has occurred in the compiler.
• VS 2019 Preview 1 - EF6 edmx file cannot be saved.
• vcruntime140.dll should be made available on Microsoft Symbol Server.
• Static Analyser, Custom Rule Set (C++) does not execute included default sets.
• VS2019 Preview: Azure Function publishing does not work.
• References window does not remember its position.
• Missing formatting option for pointers and references.
• Microsoft.TeamFoundation.Client, Version=15.0.0.0 assembly not found when create a new web project.
