(500) Internal Server Error when create storage table use development account

Question

Yesterday, our team suddenly cannot use storage emulator all, it always said 'can not create database' when start the emulator. Finally, we found a issue may affect this, we delete the WAStorageEmulatorDb30.mdf file in C:\Users\[User], and create manully
in localdb, and so we can start the storage emulator later.
But we still can not use it, since it always throw exception when creating Tables/Blobs/Queues, the exception like this:
Microsoft.WindowsAzure.Storage.StorageException was caught
HResult=-2146233088
Message=The remote server returned an error: (500) Internal Server Error.

And if we visit this url: http://127.0.0.1:10002/devstoreaccount1, it said Internal Error:

</message>
</error>
Any ideas of this? We still don't know what caused this whole trouble from yesterday, is it possible affect the storage emulator just by code? We were coding, not configuring anything. Strange.

Answer 1

I have tried it before, but not works.
Finally, I solved this issue by delete LocalDB instance, uninstall storage emulator and install LocalDB instance / storage emulator again, it works now. Quite strange.
