 ### Bugs Fixed
 - Fixed a an issue when using `TableEntity.GetDateTime` that resulted in an `InvalidOperationException` exception. ([#25323](https://github.com/Azure/azure-sdk-for-net/issues/25323)) 
-
+- `TableClient.GenerateSasUri(...)` does not throw if the client was constructed via `TableServiceClient.GetTableClient(string tableName)` ([#25881](https://github.com/Azure/azure-sdk-for-net/issues/25881))
