# Heroku .NET Core Buildpack
This is the [Heroku buildpack](https://devcenter.heroku.com/articles/buildpacks) for [ASP.NET Core](https://docs.microsoft.com/en-us/aspnet/core/).
[](https://github.com/jincod/dotnetcore-buildpack/actions)
The Buildpack supports C# and F# projects. It searchs through the repository's folders to locate a `Startup.*` or `Program.*` file. If found, the `.csproj` or `.fsproj` in the containing folder will be used in the `dotnet publish ` command.
If repository contains **multiple** Web Applications (multiple `Startup.*` or `Program.*`), `PROJECT_FILE` and `PROJECT_NAME` environment variables allow to choose project for publishing.
## Usage
### .NET Core latest stable
```
heroku buildpacks:set jincod/dotnetcore
```
### .NET Core edge
```
heroku buildpacks:set https://github.com/jincod/dotnetcore-buildpack
```
### .NET Core Preview release
```
heroku buildpacks:set https://github.com/jincod/dotnetcore-buildpack#preview
```
### Previous releases
```
heroku buildpacks:set https://github.com/jincod/dotnetcore-buildpack#version
```
Available [releases](https://github.com/jincod/dotnetcore-buildpack/releases)

## Entity Framework Core Migrations
You cannot run migrations with the `dotnet ef` commands using **.NET Local Tools** once the app is built. Alternatives include:
### Enabling Automatic Migrations
- Ensure there is a .NET local tool manifest file(dotnet-tools.json) which specifies the dotnet-ef tool:
```bash
dotnet new tool-manifest
dotnet tool install dotnet-ef
```
- 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:
```xml
```
### Manually Running Migration Scripts on the Database
- 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.
## Setting Connection String for heroku PostgreSQL
If you are using Heroku Postgres addon, then Heroku provides the database connection string as environment variable `DATABASE_URL`. In order to use this in an Npgsql connection string, do something like following:
```c#
using System.Text.RegularExpressions;
...
// Replace AppContext with your own DbContext Class
builder.Services.AddDbContext(options =>
{
if (Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT") == "Production")
{
var m = Regex.Match(Environment.GetEnvironmentVariable("DATABASE_URL")!, @"postgres://(.*):(.*)@(.*):(.*)/(.*)");
options.UseNpgsql($"Server={m.Groups[3]};Port={m.Groups[4]};User Id={m.Groups[1]};Password={m.Groups[2]};Database={m.Groups[5]};sslmode=Prefer;Trust Server Certificate=true");
}
else // In Development Environment
{
// So, use a local Connection
options.UseNpgsql(builder.Configuration.GetValue("CONNECTION_STRING"));
}
});
```
## Node.js and NPM
```bash
heroku buildpacks:set jincod/dotnetcore
heroku buildpacks:add --index 1 heroku/nodejs
```
