Describes the logical and physical names used for a connection-string reference.

## Definition

```csharp
namespace Aspire.Hosting.ApplicationModel;

public sealed record ConnectionStringEnvironmentVariableNames
    : System.IEquatable<Aspire.Hosting.ApplicationModel.ConnectionStringEnvironmentVariableNames>
{
    // ...
}
```

## Properties

- [IsExplicit](/reference/api/csharp/aspire.hosting/connectionstringenvironmentvariablenames/properties.md#isexplicit) : `bool` `get; init` -- Gets whether the physical environment-variable name was explicitly supplied by the source resource.
- [LogicalName](/reference/api/csharp/aspire.hosting/connectionstringenvironmentvariablenames/properties.md#logicalname) : `string` `get; init` -- Gets the logical connection name used by application configuration.
- [OriginalName](/reference/api/csharp/aspire.hosting/connectionstringenvironmentvariablenames/properties.md#originalname) : `string` `get; init` -- Gets the original environment-variable name derived directly from the logical name.
- [PortableName](/reference/api/csharp/aspire.hosting/connectionstringenvironmentvariablenames/properties.md#portablename) : `string` `get; init` -- Gets the portable environment-variable name.
