- [WithDotnetProgramBuildEnvironment(IResourceBuilder<T>, Func<EnvironmentCallbackContext, Task>)](/reference/api/csharp/aspire.hosting/dotnetprogramresourcebuilderextensions/methods.md#withdotnetprogrambuildenvironment-iresourcebuilder-t-func-environmentcallbackcontext-task) : [IResourceBuilder<T>](/reference/api/csharp/aspire.hosting/iresourcebuilder-1.md) `extension` `ats ignored` -- Adds a callback that configures build-only environment variables for .NET SDK container publishing.
- [WithDotnetProgramPublishing(IResourceBuilder<T>)](/reference/api/csharp/aspire.hosting/dotnetprogramresourcebuilderextensions/methods.md#withdotnetprogrampublishing-iresourcebuilder-t) : [IResourceBuilder<T>](/reference/api/csharp/aspire.hosting/iresourcebuilder-1.md) `extension` `ats ignored` -- Configures a .NET program resource to publish a container image through the .NET SDK.
