  -* Improved logic for resolving breakpoints in local functions and lambdas ([#1678](https://github.com/OmniSharp/omnisharp-vscode/issues/1678))
  +* Improved logic for resolving breakpoints in local functions and lambdas. ([#1678](https://github.com/OmniSharp/omnisharp-vscode/issues/1678))
  +* When generating a new launch.json file via "start debugging" in a workspace without a launch.json file, the extension now provides the same content as is created with the '.NET: Generate Assets for Build and Debug' command. This takes advantage of a new extensibility point from VS Code. Before the C# extension could only statically provide templates, so, for example, they couldn't have the path to the launchable project. (PR: [#1801](https://github.com/OmniSharp/omnisharp-vscode/pull/1801))

  * Pass `--no-restore` when invoking `dotnet build` to ensure that implicit restore does not run, making the build and the test run a bit faster.
