"App": { "ServerRootAddress": "https://amazingsolutions.azurewebsites.net", "ClientRootAddress": "https://amazingsolutions-client.azurewebsites.net", "CorsOrigins": "http://*.amazingsolutions.com.au,https://amazingsolutions-client.azurewebsites.net,https://amazingsolutions.azurewebsites.net" }

This config is in my appsettings.Production.json

I have built and deployed the Host project to Azure using the Release configuration.

okay that command worked I increased the memory size to 16384 for good measure now I can deploy to azure

Just incase anyone is wondering I am remoting into my azure VM and checked if the build worked. I will be creating a course very soon how to setup development environment for aspnetzero and on my website amazingsolutions.com.au

now i am getting

could this be the issue how do i resolve these warnings

How do you execute these batch files when you hit the play button and how do you go about debugging the project ?

It appears that this happens when the foreign key is a string and is required. For eg

[Required] public virtual string BranchId { get; set; }

If the foreign keys are longs, ints etc, they can be non nullable. But in case of strings, this causes a problem. It would be nice if someone could investigate whether this is a boilerplate issue or an entity framework one.

For the time being I simply do this to make it all work.. (let me know if this is wrong approach). It tends to update the LastModificationTime, DeletionTime and DeleterUserId correctly.

    public async Task Delete(EntityDto<string> input)
    {
        var lead = await _leadRepository.GetAsync(input.Id);
        if(lead != null)
        {
            lead.IsDeleted = true;
        }
    }

Yes tried that already but same error. It's happening for another table as well. Is there some way to debug this? Could it be that some packages are out of date and if so how should these packages be updated using nuget? Thanks.
