You're getting this error in Dev but not Local:

"The instance of entity type 'AssessmentItem' cannot be tracked because another instance with the same key value for {'AssessmentItemId'} is already being tracked."

This is an Entity Framework Core error that occurs when two separate instances of an entity with the same primary key are being tracked in the same DbContext. Let’s break it down:

---

✅ Why It Happens

EF Core enforces a one tracked instance per primary key rule. If you:

• Load an entity (e.g., from a query), then
• Later Attach or Insert another entity with the same primary key, EF will throw this error.

📍 Most Likely Cause in Your Code

You're doing:

var serializedCurrentAssessmentItemEntity = JsonConvert.SerializeObject(assessmentItemEntity);
var newAssessmentItemEntity = JsonConvert.DeserializeObject<AssessmentItem>(serializedCurrentAssessmentItemEntity);
...
newAssessmentItemEntity.AssessmentItemId = 0; // so it becomes a "new" insert

BUT LATER, this logic is violated here:

var asdf = await unitOfWork.AssessmentItemRepository.FindByAsync(...);

// If asdf is not null, you do:
await unitOfWork.AssessmentItemRepository.UpdateAsync(asdf);

If asdf is already being tracked AND you’re also tracking a new instance with the same AssessmentItemId, this will trigger the error.

And worse: your object graphs (sections, assessmentItems) might carry references to previously tracked entities from deserialization.

---

✅ Fix (3 Options)

Option 1: Use .AsNoTracking()

Anywhere you're querying for something that you don’t plan to update, make sure to use .AsNoTracking() to avoid the DbContext tracking that entity.

Update your repository to support it:

// In your repository FindByAsync or FindAllByAsync:
var query = dbContext.Set<T>().AsQueryable();
if (asNoTracking)
    query = query.AsNoTracking();

Use it like:

var currentAssessmentEntity = await unitOfWork.AssessmentRepository
    .FindByAsync(x => ..., cancellationToken, asNoTracking: true);

---

Option 2: Use Detach() before reusing the entity

Before reinserting deserialized copies or updating found ones, you can manually detach tracked entities like:

context.Entry(existingEntity).State = EntityState.Detached;

Or detach the whole context (not usually recommended).

---

Option 3: Use a clean DbContext scope

Instead of reusing a long-living DbContext that accumulates tracked state, do:

using (var scope = new TransactionScope(...))
{
    using (var newContext = new MyDbContext())
    {
        // work with clean context
    }
}

You can also do it with IServiceScopeFactory if using DI.

---

🕵️ Why This Works in Local But Not in Dev?

Because your Dev likely uses different EF configuration, possibly:

• SensitiveDataLogging is off (you should enable it in Dev temporarily)
• Different lifetime for DbContext (Scoped vs Singleton)
• Different records already in Dev that aren’t in local, triggering entity tracking conflict when resolving duplicates

---

✅ Suggested Next Steps

1. Enable this for clearer logs in Dev:

optionsBuilder.EnableSensitiveDataLogging();

2. Update all your repo FindBy and FindAllBy to support AsNoTracking.

3. During cloning, ensure you're only attaching new objects (with Id = 0) or objects that EF is not already tracking.

---

Want me to give you a diff of which repo queries to apply AsNoTracking() to based on the code above?

• Claude Code

Setup...

1. Docker Setup

Download and install Docker Desktop - link

• if forced to restart, launch Docker Desktop
• if you get an error about Windows Subsystem for Linux, in Powershell (as Admin) run
  wsl --update

2. SonarQube Setup

docker run -d --name sonarqube -p 9000:9000 -e SONAR_ES_BOOTSTRAP_CHECKS_DISABLE=true sonarqube:latest

!! If you get a port error

docker: Error response from daemon: ports are not available: exposing port TCP 0.0.0.0:9000 -> 127.0.0.1:0: listen tcp 0.0.0.0:9000: bind: Only one usage of each socket address (protocol/network address/port) is normally permitted.

then you can either:

1. Kill the port:
   a. Find out what's running on port 9000:
   netstat -aon | findstr :9000

   then you will see:

The Process ID is the last column (i.e., 13388)

b. Then you can kill it by taskkill /PID 13388 /F

or...

2. you can use another port (which is what I'm doing)
   docker run -d --name sonarqube -p 9001:9000 -e SONAR_ES_BOOTSTRAP_CHECKS_DISABLE=true sonarqube:latest

! If you get this error:

docker: Error response from daemon: Conflict. The container name "/sonarqube" is already in use by container "656085e89c234748d11cbdd41aaa2ece8ad3aa44f809702660eb4db88f271602". You have to remove (or rename) that container to be able to reuse that name.

Now run docker rm -f sonarqube to remove it

Then run:
docker run -d --name sonarqube -p 9001:9000 -e SONAR_ES_BOOTSTRAP_CHECKS_DISABLE=true sonarqube:latest

This spins up SonarQube on http://localhost:9000.

3. Get your SonarQube Token

1. Go to: http://localhost:9000/
2. Default credentials:
   • Username: admin
   • Password: admin
3. Click on "Account" icon in upper right
4. Click "My Account"
5. Select the "Security" tab at the top
6. Proceed to "Generate Token" as per your needs. (Set the Token Type to "User" from the Dropdown list)

4. SonarScanner

1. Download 👉 https://docs.sonarsource.com/sonarqube/latest/analyzing-source-code/scanners/sonarscanner/
2. Extract & Add to PATH

• Unzip the contents (e.g., to C:\SonarScanner)
• Then add the bin folder to your PATH environment variable:
  • Press ⊞ Win → search "Environment Variables"
  • Click “Edit the system environment variables”
  • Click “Environment Variables”
  • Under System Variables → select Path → click Edit
  • Add: C:\SonarScanner\bin (or wherever you extracted)

3. Test the Install

• Open a new terminal (so it reloads the PATH) and run:
  sonar-scanner -v

5. Install support for .NET

Temporarily disable CPS Nuget feed to avoid the 401 error in the next step

1. dotnet nuget list source
2. You should see a response like:

Registered Sources:
  1.  nuget.org [Enabled]
      https://api.nuget.org/v3/index.json
  2.  CPS [Enabled]
      https://pkgs.dev.azure.com/ComprehensivePharmacyServices/_packaging/ComprehensivePharmacyServices%40Local/nuget/v3/index.json
  3.  Microsoft Visual Studio Offline Packages [Enabled]
      C:\Program Files (x86)\Microsoft SDKs\NuGetPackages\

3. dotnet nuget disable source "CPS"
4. dotnet tool install --global dotnet-sonarscanner
5. dotnet nuget enable source "CPS"

verify it works:

dotnet sonarscanner --version

6. PAT for NuGet feed access

1. Go to Projects - Home

7. Support for internal NuGet feeds

dotnet nuget update source CPS --source https://pkgs.dev.azure.com/ComprehensivePharmacyServices/_packaging/ComprehensivePharmacyServices%40Local/nuget/v3/index.json  --username [email protected] --password PERSONAL_ACCESS_TOKEN__PAT --store-password-in-clear-text

** If needed, this will show all your nuget packages in the solution/project dotnet nuget list source

8. Install coverlet.collector

1. C:\...PATH_TO_TEST_PROJECT> dotnet add package coverlet.collector --source https://api.nuget.org/v3/index.json

2. C:\...PATH_TO_TEST_PROJECT> dotnet add package coverlet.msbuild --source https://api.nuget.org/v3/index.json

3. C:\...PATH_TO_TEST_PROJECT> dotnet clean

#Running...

Setup Code Coverage analysis

1. dotnet nuget disable source "CPS"

2. dotnet tool install --global dotnet-sonarscanner

3. C:\...PATH_TO_TEST_PROJECT> dotnet tool install --global dotnet-reportgenerator-globaltool

4. dotnet nuget enable source "CPS"

5. In VisualStudio rebuild your solution

6. C:\...PATH_TO_SOLUTION> dotnet test CPS.RxAssess.Business.Tests/CPS.RxAssess.Business.Tests.csproj --no-build /p:CollectCoverage=true /p:CoverletOutput=./TestResults/coverage.opencover.xml /p:CoverletOutputFormat=opencover

Running a scan locally...

1. C:\...PATH_TO_SOLUTION> dotnet sonarscanner begin /k:"AccountingAssistant2" /d:sonar.host.url="http://localhost:9000" /d:sonar.token="SONARQUBE_TOKEN" /d:sonar.cs.opencover.reportsPaths="AccountingAssistant.Api.Tests/TestResults/coverage.opencover.xml"

2. C:\...PATH_TO_SOLUTION> dotnet build CPS.RxAssess.sln

3. C:\...PATH_TO_SOLUTION> dotnet sonarscanner end /d:sonar.token="SONARQUBE_TOKEN"

See results
