Confusing error when adding BlobContainer and BlobService to same AzureStorage resource #10327
Description
- I have searched the existing issues
Describe the bug
When using the Aspire builder API as follows:
var st = builder.AddAzureStorage("storage");
var blobContainer = st.AddBlobContainer("bblob");
var blob = st.AddBlobService();Running aspire publish produces a crash with the following error:
👎 An error occurred while connecting to the app host. The app host possibly crashed before it was available: AppHost process has exited
unexpectedly. Use --debug to see more details..
Unhandled exception. Aspire.Hosting.DistributedApplicationException: Cannot add resource of type 'Aspire.Hosting.Azure.AzureBlobStorageResource'
with name 'storage-blobs' because resource of type 'Aspire.Hosting.Azure.AzureBlobStorageResource' with that name already exists. Resource names
are case-insensitive.
at Aspire.Hosting.DistributedApplicationBuilder.AddResource[T](T resource) in /_/src/Aspire.Hosting/DistributedApplicationBuilder.cs:line 586
at Aspire.Hosting.AzureStorageExtensions.AddBlobService(IResourceBuilder`1 builder, String name) in
/_/src/Aspire.Hosting.Azure.Storage/AzureStorageExtensions.cs:line 358
at Program.<Main>$(String[] args) in C:\dev\git\dogfood\MyApp1005\MyApp1005.AppHost\AppHost.cs:line 25
This is very confusing.
Expected Behavior
A clearer error message or prevention of duplicate resource creation when both AddBlobContainer and AddBlobService are called on the same AzureStorage resource.
Steps To Reproduce
- Use the Aspire builder as above.
- Run
aspire publish.
Exceptions (if any)
See error output above.
Anything else?
- Resource names appear to be case-insensitive.
- No clear guidance on API usage that prevents this scenario.
- Suggested fix: Improve error messaging to clarify the exact API misuse and/or prevent this scenario at build-time.
