connection-properties

You are a C# developer. Your goal is to implement and verify that an Aspire resource implements IResourceWithConnectionString.GetConnectionProperties and that it is documented, using specific rules.

IResourceWithConnectionString.GetConnectionProperties rules

Common Connection properties are

• Host
• Port
• Password, when available
• UserName, when available
• Uri, representing a service resource url, like [protocol]://[username]:[password]@[host]:[port]/[subresource]?parameter=...
• Azure, ONLY when the resource may be hosted on Azure or not based on the context. With the value "true" if the resource is hosted on Azure, or "false" otherwise. This MUST NOT be defined when the resource doesn't have a IsContainer, IsEmulator or InnerResource property.
• DatabaseName
• JdbcConnectionString, a JDBC connection string format for the specific resource (search online Azure SDK documentation for reference formats).

If a JdbcConnectionString property doesn't exist and there is online documentation about connecting to this resource using JDBC, create it.

Parent resources

When a resource class implement IResourceWithParent its connection properties should inherit its parent's ones. Then define it own to override the values, like Uri if applicable.

To inherit parent properties use the ConnectionPropertiesExtensions.CombineProperties method like this:

IEnumerable<KeyValuePair<string, ReferenceExpression>> IResourceWithConnectionString.GetConnectionProperties() =>
    Parent.CombineProperties([
        new("Database", ReferenceExpression.Create($"{DatabaseName}")),
        new("Uri", UriExpression),
        new("JdbcConnectionString", JdbcConnectionString),
    ]);

Where Parent comes from the IResourceWithParent interface.

Documentation

Each Azure resource has an associated README.md file in the same folder. Update the README with the list of Connection Properties defined in GetConnectionProperties.

Here is a sample section for Sql Server:

## Connection Properties

When you reference a SQL Server resource using `WithReference`, the following connection properties are made available to the consuming project:

### SQL Server server

The SQL Server server resource exposes the following connection properties:

| Property Name | Description |
|---------------|-------------|
| `Host` | The hostname or IP address of the SQL Server |
| `Port` | The port number the SQL Server is listening on |
| `Username` | The username for authentication |
| `Password` | The password for authentication |
| `Uri` | The connection URI in mssql:// format, with the format `mssql://{Username}:{Password}@{Host}:{Port}` |
| `JdbcConnectionString` | JDBC-format connection string, with the format `jdbc:sqlserver://{Host}:{Port};trustServerCertificate=true`. User and password credentials are provided as separate `Username` and `Password` properties. |

### SQL Server database

The SQL Server database resource inherits all properties from its parent `SqlServerServerResource` and adds:

| Property Name | Description |
|---------------|-------------|
| `Uri` | The connection URI in mssql:// format, with the format `mssql://{Username}:{Password}@{Host}:{Port}/{DatabaseName}` |
| `JdbcConnectionString` | JDBC connection string with database name, with the format `jdbc:sqlserver://{Host}:{Port};trustServerCertificate=true;databaseName={DatabaseName}`. User and password credentials are provided as separate `Username` and `Password` properties. |
| `Database` | The name of the database |

Aspire exposes each property as an environment variable named `[RESOURCE]_[PROPERTY]`. For instance, the `Uri` property of a resource called `db1` becomes `DB1_URI`.

• The table should be formatted identically to this sample
• Each resource gets its own table
• Uri and JdbcConnectionString must have their format in the description
• The Connection Properties should be the last before external links like Additional documentation
