[Failed] Try to implement NativeAOT support.

Add: NativeAOT support with EF Core. However failed for compiled binary throw Exception in queries. Wait for a stable support for NativeAOT.

Add: document for intergration EF Core with NativeAOT.

+# EFCore Intergration
+
+## Introduction
+
+This app relies on EF Core to access the database.
+
+However, it is NOT so smooth when work with NativeAOT.
+
+To use EF Core, see below.
+
+## DesignTimeDbContextFactory
+
+To work with NativeAOT, a code-defined way to create DbContext instance is a MUST in nearly ALL operations of EF Core, letting ef tool discover the DbContext.
+
+In this project, `OptixServe.Infrastructure/Utilites/DesignTimeDbContextFactory.cs` is set up to do this.
+
+This class implements a simple commandline arguments parser, enabling passing arguments along with `dotnet ef`.
+
+Currently, there are two options, `--config/-c` and `--data-dir/-d` are supported. See documents there.
+
+To pass arguments/options to `CreateDbContext` static method, pass the arguments following with `dotnet ef` command, with two dashes splitting.
+
+For example:
+
+```bash
+dotnet ef database update -- -c ../data/appsettings.Development.json -d ../data/
+```
+
+## Workflow
+
+To make the code work, following the steps:
+
+1. Implement other parts
+2. Compile the data models, with `--nativeaot` option.
+3. Add migration
+4. Update database
+5. Build project, and Run!
+
+Here are the details.
+
+### Requirements
+
+See [https://learn.microsoft.com/en-us/ef/core/performance/nativeaot-and-precompiled-queries]()
+
+### Compile Models
+
+```bash
+dotnet ef dbcontext optimize --output-dir Data/CompiledModels --precompile-queries --nativeaot -- -c ../data_dev/appsettings.Development.json -d ../data_dev/
+```
+
+If this is the first time to run `dbcontext optimize`, DO NOT forget to `UseModel` in DbContext construction.
+
+```cs OptixServe.Infrastructure/Utilites/DatabaseHelper.cs
+public static void ConfigureDbContext(DbContextOptionsBuilder options)
+{
+    // ...
+    options.UseSqlite(connectionString, b => b.MigrationsAssembly("OptixServe.Infrastructure"))
+        .UseModel(AppDbContextModel.Instance);
+    // ...
+}
+```
+
+
+### Add Migration
+
+```bash
+dotnet ef migrations add InitialCreate -- -c ../data_dev/appsettings.Development.json
+```
+
+
+### Update Database
+
+```bash
+dotnet ef database update -- -c ../data_dev/appsettings.Development.json -d ../data_dev/
+```
+
+
+### Build Project
+
+```bash
+dotnet publish -c Release -r linux-x64
+```
