nswag openapi add a global return type for a specific response code

Hey, I have an API that has routes which are defined like below; but I return some 401s and others via middleware, is there a way to say that all routes could return a specific response type using openAPI?

    [HttpPost("UpdatePersonalInformation")]
    [ProducesResponseType(typeof(UpdatePersonalInformationResponse), 200)]
    [ProducesResponseType(typeof(AppError), 400)]
    public async Task<IActionResult> UpdatePersonalInformation(
        [FromBody] UpdatePersonalInformationRequest request)

    [HttpPost("UpdatePersonalInformation")]
    [ProducesResponseType(typeof(UpdatePersonalInformationResponse), 200)]
    [ProducesResponseType(typeof(AppError), 400)]
    public async Task<IActionResult> UpdatePersonalInformation(
        [FromBody] UpdatePersonalInformationRequest request)

nswag (OpenApi) typescript get error type

Hey, I'm generating an api client using nswag, here is an example route:

[HttpPost("BeginLogin")]
    [ProducesResponseType(typeof(AppError), 400)]
    [ProducesResponseType(typeof(BeginLoginResponse), 200)]
    public async Task<ActionResult> BeginLogin([FromBody] BeginLoginRequest request)

[HttpPost("BeginLogin")]
    [ProducesResponseType(typeof(AppError), 400)]
    [ProducesResponseType(typeof(BeginLoginResponse), 200)]
    public async Task<ActionResult> BeginLogin([FromBody] BeginLoginRequest request)

However, in the client itself the response is not a union type, but simply the 200 default type... How am I supposed to get the error in the frontend (typescript)?

beginLogin(authorization: any | undefined, request: BeginLoginRequest): Promise<BeginLoginResponse>{}

beginLogin(authorization: any | undefined, request: BeginLoginRequest): Promise<BeginLoginResponse>{}

❔ how do delay the process exit for a graceful shutdown in a console app?

Hey, I want to delay the app exit by a few seconds, I tried using the following but it's just exiting instantaneously

AppDomain.CurrentDomain.ProcessExit += delegate(object sender, EventArgs eventArgs)
        {
            GlobalState.CancellationRequested = true;
            LogService.EzLogger.LogInfoAsync("[PROCESSOR] Shutting down gracefully", null);
            Console.WriteLine("Shutting down...");  
            Thread.Sleep(TimeSpan.FromSeconds(30));
            Console.WriteLine("Finished shutting down...");
        };

❔ How to use build directory as working directory in debug

Hey, I have a class library that has a .json file in a sub-directory, it's marked as content and copies to the output folder. I reference this class library project, it builds properly to the selected output directory and the json file is there, but it seems like the working directory for the app that references the library is that of the .csproj, and since the json file is in the other project, when running the app it cannot find the file, how do I say that I want to run the app from the build directory and not project directory? (VS 2022)

❔ postgres EF core, how to have a custom connection string config file

Hey, I have a net6 class library with a DbContext, I want to have the connection string in a separate custom config file, code below. For some reason, when I do dotnet ef database update, an error pops up:

System.ArgumentException: Couldn't set min pool size (Parameter 'min pool size')
 ---> System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary. *...*

My connection string looks like this:

User ID=postgres;Password=<PASSWORD>;Host=localhost;Port=5432;Database=NetSendHost;Pooling=true;Min Pool Size=0;Max Pool Size=250;Connection Lifetime=0;

    public class Db : DbContext

            ConnectionString = obj.RootElement.GetProperty("PgSqlConnectionString").GetString();
        }

        protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
        {
            optionsBuilder.UseNpgsql(ConnectionString);
        }
        public DbSet<PrivateServerUser> ServerUsers { get; set; }

    }

MAUI Webview target=_blank href redirects not working on android

I have an MAUI app that is essentially a WebView that hosts a wordpress website. My problem is that whenever I try to load an external link it will simply not load the "href" redirect... It works fine on Windows and iOS devices, but not in android. EDIT: The href is a "_blank" target. Is there a specific permission I need in the manifest? In case it helps, here is the code for the page:

<?xml version="1.0" encoding="utf-8" ?>

    <Grid BackgroundColor="DarkSlateGrey">
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>
        <StackLayout Grid.Row="0" Grid.Column="0" 
                         Spacing="5" Orientation="Horizontal" Padding="8">
            <Button Text="Go Back" TextColor="DarkSlateGray" BackgroundColor="White"/>
            <Button Text="Change Language" x:Name="ChangeLangBtn" TextColor="DarkSlateGray" BackgroundColor="White"/>
        </StackLayout>
        <WebView Grid.Row="1" Grid.Column="0" 
                     Source="https://example.com"
                     x:Name="WebView"/>
    </Grid>

<?xml version="1.0" encoding="utf-8" ?>

    <Grid BackgroundColor="DarkSlateGrey">
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>
        <StackLayout Grid.Row="0" Grid.Column="0" 
                         Spacing="5" Orientation="Horizontal" Padding="8">
            <Button Text="Go Back" TextColor="DarkSlateGray" BackgroundColor="White"/>
            <Button Text="Change Language" x:Name="ChangeLangBtn" TextColor="DarkSlateGray" BackgroundColor="White"/>
        </StackLayout>
        <WebView Grid.Row="1" Grid.Column="0" 
                     Source="https://example.com"
                     x:Name="WebView"/>
    </Grid>

And here is the manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:versionCode="2" android:versionName="2">
    <application android:allowBackup="true" android:icon="@mipmap/appicon" android:roundIcon="@mipmap/appicon_round" android:supportsRtl="true" android:label="MYAPPNAME"></application>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-sdk android:minSdkVersion="21" android:targetSdkVersion="31" />
</manifest>

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:versionCode="2" android:versionName="2">
    <application android:allowBackup="true" android:icon="@mipmap/appicon" android:roundIcon="@mipmap/appicon_round" android:supportsRtl="true" android:label="MYAPPNAME"></application>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-sdk android:minSdkVersion="21" android:targetSdkVersion="31" />
