Trouble with QuickStart for ScimEF project

Followed all the Quickstart instructions. Got to ScimEF project and ran into some errors.

Bypassed one error by commenting out the check for StorageTypes.SQLITE in Program.cs.

But I don't know what to do about this error:

Hello,

There is indeed an issue with the .NET template project version 5.0.2.

The IMessageDataRepository is not configured correctly, but this issue has been resolved in version 5.0.3.

You can either wait for the 5.0.3 release (expected at the end of February) or add the missing dependency manually as follows:

services.AddSingleton<IMessageDataRepository>(new InMemoryMessageDataRepository());

Refer to this issue : #808
