Compiler Warning ASPIRECOMPUTE002

Version introduced: 13.0

The GetHostAddressExpression method is for evaluation purposes only and is subject to change or removal in future updates. Suppress this diagnostic to proceed.

This diagnostic warning is reported when using the experimental GetHostAddressExpression method from the IComputeEnvironmentResource interface.

Example

The following code generates ASPIRECOMPUTE002:

var builder = DistributedApplication.CreateBuilder(args);

var computeEnv = builder.AddAzureContainerAppEnvironment("env");

// Accessing GetHostAddressExpression on a compute environment resource
var endpoint = computeEnv.Resource.GetEndpoint("http");
var hostAddress = computeEnv.Resource.GetHostAddressExpression(endpoint);

Understanding GetHostAddressExpression

The GetHostAddressExpression method is part of the IComputeEnvironmentResource interface and provides a way to retrieve the host address or hostname for a specified endpoint reference as a ReferenceExpression.

Key characteristics

Returns host only — The returned value contains only the hostname or address, without scheme, port, or path information
Reference expression — Returns a ReferenceExpression that can be evaluated in different contexts
Compute environment specific — Designed for use with compute environment resources like Azure Container Apps, Kubernetes, or Docker Compose

This method is useful when you need to configure resources with just the hostname rather than a full URL, which is common in scenarios like:

Configuring service-to-service communication within a compute environment
Setting up DNS-based service discovery
Configuring load balancers or ingress controllers

To suppress this warning

Suppress the warning with either of the following methods:

Set the severity of the rule in the .editorconfig file.
.editorconfig
```
[*.{cs,vb}]
dotnet_diagnostic.ASPIRECOMPUTE002.severity = none
```
For more information about editor config files, see Configuration files for code analysis rules.

Add the following PropertyGroup to your project file:

<PropertyGroup>
    <NoWarn>$(NoWarn);ASPIRECOMPUTE002</NoWarn>
</PropertyGroup>

Suppress in code with the #pragma warning disable ASPIRECOMPUTE002 directive:

var builder = DistributedApplication.CreateBuilder(args);

var computeEnv = builder.AddAzureContainerAppEnvironment("env");

#pragma warning disable ASPIRECOMPUTE002
var endpoint = computeEnv.Resource.GetEndpoint("http");
var hostAddress = computeEnv.Resource.GetHostAddressExpression(endpoint);
#pragma warning restore ASPIRECOMPUTE002
