I've got following setup: C#, ServiceStack, MariaDB, POCOs with objects and structs, JSON.
The main question is: how to use ServiceStack to store POCOs to MariaDB having complex types (objects and structs) blobbed as JSON and still have working de/serialization of the same POCOs? All of these single tasks are supported, but I had problems when all put together mainly because of structs.
... finally during writing this I found some solution and it may look like I answered my own question, but I still would like to know the answer from more skilled people, because the solution I found is a little bit complicated, I think. Details and two subquestions arise later in the context.
Sorry for the length and for possible misinformation caused by my limited knowledge.
Simple example. This is the final working one I ended with. At the beginning there were no
SomeStruct.ToString()/Parse() methods and no

ServiceStack treats structs like a single scalar value type, just like most of the core BCL Value Types (e.g.
DateTime, etc). Overloading the
ToString() methods and Struct's
Constructor let you control the serialization/deserialization of custom structs.
Docs have been corrected. Structs use
Parsewhilst classes use
If you want to serialize a models properties I'd suggest you use a
class instead as the behavior you're looking for is that of a POCO DTO.
If you want to have structs serailized as DTOs in your RDBMS an alternative you can try is to just use JSON.NET for the complex type serialization, e.g:
I'm using ServiceStack.OrmLite, and when trying to set the default column definition for DateTime, I can’t manage to get the column to be nullable. Everything else sticks, but "NULL" is somehow converted into "NOT NULL".
In my example code below I've set
ColumnDefinition => "DATETIME(6) NULL DEFAULT... and when running it, it creates a table with
DATETIME(6) NOT NULL...

If you want to specify a nullable ValueType RDBMS column it needs to be nullable on the C# Type, e.g:

This isn't going to be an issue with OrmLite which just sends the SQL as-is to Npgsql ADO.NET provider which is returning the server PostgreSQL error.
For some reason the connection string doesn't have visibility or access to your
product_book materialized view, some potential issues could be the user may not have access to it, or it's in a different schema.

This indicates you have different version of ServiceStack packages. You need to make sure that all packages have the same version, e.g. 5.9.0.

The issue is ServiceStack's
AuthenticateService is trying to populate the
AuthenticateResponse Roles and Permissions but your Custom AuthProvider isn't populating the
session.UserAuthId which is used to query the Auth Repository for the roles.
The solution is for your Custom AuthProvider to populate the Sessions
UserAuthId with the Id of the Authenticated User.
You can also prevent this Exception by disabling ServiceStack from trying to populate the Roles/Permissions by setting
I started a ServiceStack ASP.NET Empty project in VS2019, as that was the closest thing I could find to what I wanted. The template is right on, but I want to run it in .NET Core.
However, the Target framework was set to .NET Framework 4.5, but I wanted it to be .NET Core 2.1+, and I cannot select it either:
I know that I have .NET Core installed, because I have been developing a Blazor app also in VS2019, which is .NET Core.

I have an implementation, where I am calling an autoquery operation via the service gateway. The service gateway will successfully call both internal and external operations. However, any autoquery operation fails because it is not getting the connection string set. These same autoquery operations work just fine when called directly and not through the gateway.
Here is the stack trace....

Request Filter Attributes like
[ConnectionInfo] is only applied on HTTP Requests, not internal Service Gateway requests.
The Connection info isn't configured because it's not annotated on your
PostContact Service Request DTO that calls the in-procces Service Gateway.
You can have the
[ConnectionInfo] on the
QueryFiles AutoQuery Request DTO attached to the current Request with:
