Heroku .NET Core Buildpack

This is the Heroku buildpack for ASP.NET Core.

The Buildpack will search through the repository's folders to locate a Startup.cs or Program.cs file. If found, the .csproj in the containing folder will be used in the dotnet publish <project>.csproj command.

If repository contains multiple Web Applications (multiple Startup.cs), PROJECT_FILE and PROJECT_NAME environment variables allow to choose project for publishing.

You cannot run migrations with the dotnet ef commands once the app is built. Alternatives include:

• Ensure the ASPNETCORE_ENVIRONMENT environment variable is set to Production. ASP.NET Core scaffolding tools may create files that explicitly set it to Development. Heroku config will override this (heroku config:set ASPNETCORE_ENVIRONMENT=Production).
• Configure your app to automatically run migrations at startup by adding the following to the .csproj file:

<Target Name="PrePublishTarget" AfterTargets="Publish">
  <Exec Command="dotnet ef database update" />
</Target>

• Configure your connection string string appropriately, for example, for PostgreSQL:

sslmode=Prefer;Trust Server Certificate=true

• Manually run SQL scripts generated by Entity Framework Core in your app's database. For example, use PG Admin to connect your Heroku Postgres service.
