Property Value

DistributedApplicationExecutionContext

Examples

An example of using the IsRunMode property on the IDistributedApplicationBuilder via the ApplicationBuilder. In this case an extension method is used to generate a stable node name for RabbitMQ for local development runs.

private static IResourceBuilder<RabbitMQServerResource> RunWithStableNodeName(this IResourceBuilder<RabbitMQServerResource> builder)
{
    if (builder.ApplicationBuilder.ExecutionContext.IsRunMode)
    {
        builder.WithEnvironment(context =>
        {
            // Set a stable node name so queue storage is consistent between sessions
            var nodeName = $"{builder.Resource.Name}@localhost";
            context.EnvironmentVariables["RABBITMQ_NODENAME"] = nodeName;
        });
    }

    return builder;
}

Remarks

The ExecutionContext property provides access key information about the context in which the distributed application is running. The most important properties that the DistributedApplicationExecutionContext provides is the IsPublishMode and IsRunMode properties. Developers building .NET Aspire based applications may whish to change the application model depending on whether they are running locally, or whether they are publishing to the cloud.
