This Codespace can help you debug the source build of .NET. In case you have run this from a `dotnet/installer` PR branch, it will contain the VMR (`dotnet/dotnet`) checked out into `/workspaces/dotnet` with the PR changes pulled into it. You can then attempt to source-build the VMR which is what the VMR leg in the installer PR build doing. This build takes about 45 minutes and, after completion, produces an archived .NET SDK in `/workspaces/artifacts/x64/Release`. To build the VMR, run following: ```bash cd /workspaces/dotnet unset RepositoryName ./build.sh --online ``` > Please note that, at this time, the build modifies some of the checked-in sources so it might be preferential to rebuild the Codespace between attempts. For more details, see the instructions at https://github.com/dotnet/dotnet.
