+# .NET Core 1.1 → .NET 10 Migration Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Migrate the three-project solution (GR.Repository, GR.Services, GR.Mvc) from .NET Core 1.1 to .NET 10 (LTS) with MongoDB.Driver 3.x and the minimal-hosting model.
+
+**Architecture:** Bottom-up migration following the project dependency graph: GR.Repository (class lib, MongoDB) → GR.Services (class lib) → GR.Mvc (ASP.NET Core MVC web app). Each project is retargeted, its packages updated, and the build verified before moving up. The web app's `Program`/`Startup` pair is replaced by a single minimal-hosting `Program.cs`. Obsolete tooling (bower, BrowserLink, BundlerMinifier, Application Insights 2.0, `DotNetCliToolReference`) is removed; the static files already committed under `wwwroot/lib` keep working as-is.
+
+**Tech Stack:** .NET 10 SDK (10.0.101 installed locally), ASP.NET Core 10 (framework reference, no Microsoft.AspNetCore.* packages), MongoDB.Driver 3.x.
+
+**Environment notes:**
+- Verify build with `dotnet build GR.Mvc.sln` after every task.
+- There are no existing tests, so verification is compile + run + manual smoke. MongoDB connection string in `appsettings.json` is a placeholder — runtime smoke test only confirms the app starts and serves `/Home/About` (no DB) unless a real MongoDB is available (`docker run -d -p 27017:27017 mongo` works for a full CRUD smoke test).
+- Commit after each task.
+
+---
+
+### Task 1: Pin the SDK and retarget GR.Repository to net10.0 with MongoDB.Driver 3.x
+
+**Files:**
+- Create: `global.json`
+- Modify: `GR.Repository/GR.Repository.csproj`
+
+- [ ] **Step 1: Create `global.json` at repo root**
+
+```json
+{
+  "sdk": {
+    "version": "10.0.101",
+    "rollForward": "latestFeature"
+  }
+}
+```
+
+- [ ] **Step 2: Replace `GR.Repository/GR.Repository.csproj` contents**
+
+```xml
+<Project Sdk="Microsoft.NET.Sdk">
+
+  <PropertyGroup>
+    <TargetFramework>net10.0</TargetFramework>
+    <Nullable>disable</Nullable>
+    <ImplicitUsings>disable</ImplicitUsings>
+  </PropertyGroup>
+
+  <ItemGroup>
+    <PackageReference Include="MongoDB.Driver" Version="3.5.0" />
+  </ItemGroup>
+
+</Project>
+```
+
+(`Nullable`/`ImplicitUsings` stay off to avoid touching every source file; existing explicit `using` directives keep working. Check `dotnet package search MongoDB.Driver --exact-match` for the actual latest 3.x and use that version.)
+
+- [ ] **Step 3: Build the project**
+
+Run: `dotnet build GR.Repository/GR.Repository.csproj`
+Expected: likely SUCCESS. MongoDB.Driver 2.4→3.x is a major-version jump, but this repo only uses `MongoClient`, `GetDatabase`, `GetCollection`, `InsertOneAsync`, `ReplaceOneAsync`, `Find`, `FindOneAndDeleteAsync`, `Builders<T>.Filter`, `BsonClassMap`, `ConventionPack`, `ObjectId` — all still present in 3.x. If a compile error appears, fix only the signature that broke (e.g. `ReplaceOneAsync` overload ambiguity: pass `(ReplaceOptions)null` instead of `null`).
+
+Known nullable-overload gotcha in `Repository.cs:102` — if `InsertOneAsync(entity, null, cancellationToken)` is ambiguous, change to:
+
+```csharp
+await Collection.InsertOneAsync(entity, options: null, cancellationToken: cancellationToken);
+```
+
+and in `Repository.cs:125`, if `ReplaceOneAsync(idFilter, entity, null, cancellationToken)` is ambiguous:
+
+```csharp
+var result = await Collection.ReplaceOneAsync(idFilter, entity, (ReplaceOptions)null, cancellationToken);
+```
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add global.json GR.Repository/
+git commit -m "chore: retarget GR.Repository to net10.0, MongoDB.Driver 3.x"
+```
+
+---
+
+### Task 2: Retarget GR.Services to net10.0
+
+**Files:**
+- Modify: `GR.Services/GR.Services.csproj`
+
+- [ ] **Step 1: Replace `GR.Services/GR.Services.csproj` contents**
+
+```xml
+<Project Sdk="Microsoft.NET.Sdk">
+
+  <PropertyGroup>
+    <TargetFramework>net10.0</TargetFramework>
+    <Nullable>disable</Nullable>
+    <ImplicitUsings>disable</ImplicitUsings>
+  </PropertyGroup>
+
+  <ItemGroup>
+    <ProjectReference Include="..\GR.Repository\GR.Repository.csproj" />
+  </ItemGroup>
+
+</Project>
+```
+
+- [ ] **Step 2: Build**
+
+Run: `dotnet build GR.Services/GR.Services.csproj`
+Expected: SUCCESS (pure C# code, no framework-specific APIs).
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add GR.Services/GR.Services.csproj
+git commit -m "chore: retarget GR.Services to net10.0"
+```
+
+---
+
+### Task 3: Retarget GR.Mvc to net10.0 and adopt minimal hosting
+
+**Files:**
+- Modify: `GR.Mvc/GR.Mvc.csproj`
+- Modify: `GR.Mvc/Program.cs`
+- Delete: `GR.Mvc/Startup.cs`
+- Modify: `GR.Mvc/appsettings.json`
+- Modify: `GR.Mvc/Properties/launchSettings.json`
+
+- [ ] **Step 1: Replace `GR.Mvc/GR.Mvc.csproj` contents**
+
+All `Microsoft.AspNetCore.*` and `Microsoft.Extensions.*` packages come from the `Microsoft.NET.Sdk.Web` framework reference now — no PackageReferences needed. BrowserLink, CodeGeneration.Tools (`DotNetCliToolReference` is dead since SDK 2.x), `PackageTargetFallback`, and ApplicationInsights 2.0 are dropped.
+
+```xml
+<Project Sdk="Microsoft.NET.Sdk.Web">
+
+  <PropertyGroup>
+    <TargetFramework>net10.0</TargetFramework>
+    <Nullable>disable</Nullable>
+    <ImplicitUsings>disable</ImplicitUsings>
+  </PropertyGroup>
+
+  <ItemGroup>
+    <ProjectReference Include="..\GR.Repository\GR.Repository.csproj" />
+    <ProjectReference Include="..\GR.Services\GR.Services.csproj" />
+  </ItemGroup>
+
+</Project>
+```
+
+- [ ] **Step 2: Replace `GR.Mvc/Program.cs` with minimal hosting (absorbs Startup.cs)**
+
+```csharp
+using GR.Services;
+using Microsoft.AspNetCore.Builder;
+using Microsoft.Extensions.Configuration;
+using Microsoft.Extensions.DependencyInjection;
+using Microsoft.Extensions.Hosting;
+
+var builder = WebApplication.CreateBuilder(args);

+var app = builder.Build();
+

+    pattern: "{controller=Ticket}/{action=Index}/{id?}");
+
+app.Run();
+```
+
+Notes: `WebApplication.CreateBuilder` already loads `appsettings.json`, `appsettings.{Env}.json`, environment variables, and console logging — the old `Startup` constructor and `loggerFactory.AddConsole/AddDebug` code is fully replaced. `UseDeveloperExceptionPage` is automatic in Development.
+
+- [ ] **Step 3: Delete `GR.Mvc/Startup.cs`**
+
+```bash
+rm GR.Mvc/Startup.cs
+```
+
+- [ ] **Step 4: Update `GR.Mvc/appsettings.json` to the modern logging schema**
+
+```json
+{
+  "Logging": {
+    "LogLevel": {
+      "Default": "Warning",
+      "Microsoft.AspNetCore": "Warning"
+    }
+  },
+  "ConnectionStrings": {
+    "MongoConnectionString": "mongodb://localhost:27017/GR"
+  }
+}
+```
+
+Also update `GR.Mvc/appsettings.Development.json` to the same schema (keep its existing LogLevel values, just drop `IncludeScopes` if present).
+
+- [ ] **Step 5: Replace `GR.Mvc/Properties/launchSettings.json`**
+
+```json
+{
+  "profiles": {
+    "GR.Mvc": {
+      "commandName": "Project",
+      "launchBrowser": true,
+      "applicationUrl": "http://localhost:5000",
+      "environmentVariables": {
+        "ASPNETCORE_ENVIRONMENT": "Development"
+      }
+    }
+  }
+}
+```
+
+- [ ] **Step 6: Build the whole solution**
+
+Run: `dotnet build GR.Mvc.sln`
+Expected: SUCCESS, 0 errors. Warnings about obsolete MVC patterns are acceptable.
+
+Likely error to fix: `GR.Mvc/Controllers/HomeController.cs` `Error()` action may reference old patterns — if `Error.cshtml` or the controller fails, the fix is in Task 4.
+
+- [ ] **Step 7: Commit**
+
+```bash
+git add -A GR.Mvc/ GR.Mvc.sln
+git commit -m "feat: migrate GR.Mvc to net10.0 with minimal hosting"
+```
+
+---
+
+### Task 4: Clean out dead tooling (bower, BundlerMinifier) and verify views
+
+**Files:**
+- Delete: `GR.Mvc/bower.json`, `GR.Mvc/.bowerrc`, `GR.Mvc/bundleconfig.json`
+- Check: `GR.Mvc/Views/**/*.cshtml`, `GR.Mvc/Views/_ViewImports.cshtml`
+
+- [ ] **Step 1: Delete bower/bundler config (the built assets in `wwwroot/lib` and `*.min.*` are committed and keep working)**
+
+```bash
+git rm GR.Mvc/bower.json GR.Mvc/.bowerrc GR.Mvc/bundleconfig.json
+```
+
+- [ ] **Step 2: Verify `_ViewImports.cshtml` contains the tag helper registration**
+
+It must contain (add if missing):
+
+```cshtml
+@using GR.Mvc
+@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers
+```
+
+- [ ] **Step 3: Grep views for removed 1.1-era constructs**
+
+Run: `grep -rn "asp-append-version\|environment names=\|Microsoft.ApplicationInsights" GR.Mvc/Views/`
+
+- `<environment names="Development">` → change attribute to `include="Development"` / `exclude="Development"` (old syntax still works but is deprecated; update if found).
+- Any `@inject Microsoft.ApplicationInsights...` or `@Html.ApplicationInsightsJavaScript...` lines in `_Layout.cshtml` → delete them (the package was removed in Task 3).
+
+- [ ] **Step 4: Build solution again**
+
+Run: `dotnet build GR.Mvc.sln`
+Expected: SUCCESS. Razor views compile at build time in .NET 10, so view errors surface here — fix any reported `.cshtml` line directly (typical fixes are the two patterns in Step 3).
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add -A
+git commit -m "chore: remove bower/bundler tooling, fix views for net10.0"
+```
+
+---
+
+### Task 5: Runtime smoke test
+
+**Files:** none (verification only)
+
+- [ ] **Step 1: Run the app**
+
+Run: `ASPNETCORE_ENVIRONMENT=Development dotnet run --project GR.Mvc/GR.Mvc.csproj --urls http://localhost:5000` (background)
+Expected: `Now listening on: http://localhost:5000`
+
+- [ ] **Step 2: Hit a no-database page**
+
+Run: `curl -s -o /dev/null -w "%{http_code}" http://localhost:5000/Home/About`
+Expected: `200`
+
+- [ ] **Step 3 (optional, requires MongoDB): full CRUD smoke**
+
+If Docker is available: `docker run -d --name gr-mongo -p 27017:27017 mongo`, then
+`curl -s -o /dev/null -w "%{http_code}" http://localhost:5000/` — Expected `200` (Ticket Index hits MongoDB via `GetAll`).
+Then `curl -s -X POST http://localhost:5000/Ticket/AddOrUpdate -d "Title=test&Version=0"` and confirm `/` shows the ticket.
+Clean up: `docker rm -f gr-mongo`.
+
+If no Docker/MongoDB, note in the final report that DB paths were not runtime-verified.
+
+- [ ] **Step 4: Stop the app and commit nothing — report results**
+
+---
+
+### Task 6 (optional hardening, do only if user wants it): fix latent bugs surfaced during migration
+
+These pre-exist the migration and are out of scope unless requested:
+- `TicketService` creates **two** `Repository<Ticket>` instances (base ctor + `_ticketRepository` field, which is never used) — the field can be deleted.
+- `TicketController.AddOrUpdate` increments `Version`/sets timestamps that `Repository.Insert`/`Update` set again (double increment).
+- `Repository.Pagination` ignores its `orderBy` parameter.
