Unity - Reusable components, how?

Hey, I created a simple model in blender, exported it and doing some stuff with it now in Unity. So I have a .fbx file in my assets and my hierachy, added scripts and stuff to it and using it in other scripts. Now I'm thinking about having multiple objects. How would I this now? Would I drag the component into my assets folder - so create a prefab and then drag multiple items into the hierarchy again, or do you do that via code? Or even somehow else? The dragging seems kinda redundant to me somehow

Build order with dotnet build ...?

Hi, Im using VS code for my C# development. I have some MSBuild Tasks that create assets that are used by other projects. Now, when I run dotnet build at solution level, the asset producing projects always run late. So I have to run it twice. I created a script to build each project in order by calling dotnet build on the project level. However, some commands like dotnet publish or dotnet release seem to work better and easier on the solution level. So I wonder is there maybe a trick to define the order? Maybe in the *.sln file? Or can I define it in the debug|release section somewhere?

Api Method Name Attribute

Hi, i just wonder what the name property inside the HttpMethod attribute is for? I read it can be used in MVC a lot when calling other controllers or getting their routes. So I have something like

[HttpDelete(Name = "DeleteLocation")]
public IActionResult Delete([FromQuery] int id)
{
     return Ok(""Deleted"");
}

[HttpDelete(Name = "DeleteLocation")]
public IActionResult Delete([FromQuery] int id)
{
     return Ok(""Deleted"");
}

Im usually used to something like [HttpDelete("{id}")]. I cannot specify both, right? I just create an api and want to be documentative/verbose about my code

✅ Roslyn: Get file scoped namespace

Hi, i'm using the new file scoped namespace

using System;

namespace TestNamespaceSpace;

public class TestClass 
{

}

using System;

namespace TestNamespaceSpace;

public class TestClass 
{

}

I try to extract the namespace like this

var root = syntaxTree.GetRoot();
var controllerClasses = root.DescendantNodes().OfType<ClassDeclarationSyntax>()
                            .Where(IsControllerClass);

var @namespace = root.DescendantNodesAndSelf().OfType<NamespaceDeclarationSyntax>().FirstOrDefault();

var root = syntaxTree.GetRoot();
var controllerClasses = root.DescendantNodes().OfType<ClassDeclarationSyntax>()
                            .Where(IsControllerClass);

var @namespace = root.DescendantNodesAndSelf().OfType<NamespaceDeclarationSyntax>().FirstOrDefault();

but @namespace is null. Why is that?

Hey, I have this code

using GitManager.Domain.Models;
using GitManager.GitCLI.Commands.Parsing;

namespace GitManager.GitCLI.Commands

            return result;

            return result;
        }
    }
}

and i want to use to probably like this

Branch branch = await gitHandler.ExecuteAsync(new GitPullBranchCommandInput(""));

Branch branch = await gitHandler.ExecuteAsync(new GitPullBranchCommandInput(""));

But it says i cannot the determine the types... why not?! they are clearly given..

Add app created with ng new to solution

Hi, is there a way to include an app created with ng new to the solution? My goal is start that app without any host using npm run within Visual Studio. Is there some kind of *.proj file or any other way to do it? Actually, the app should also be visibile in Visual Studio, that's also why I want to add it to the solution file.

❔ WPF - Use command of viewmodel instead of item on click

Hi, I have a list of strings and display them as buttons. The list is held by a viewmodel and the viewmodel has a Command for the button click. Now, instead of creating an object for strings and add the Command to the items, I would like to have the Command at the viewmodel level.

❔ Prism: Change view in region - How to add multiple views to region and activate?

Hey, currently I'm developing a WPF application that has a navigation menu on the left (basically a treeview) and a content panel on the right. Whenever I click on a treeview item, the details about that item should be displayed on the right side within the content panel. There are different types of items and each type has a view and a viewmodel. How do I add multiple views to a region and activate one at a time? I added the views like this

            var regionmanager = Container.Resolve<IRegionManager>();
            regionmanager.RegisterViewWithRegion(RegionNames.ContentRegion, typeof(PersonDetails));
            regionmanager.RegisterViewWithRegion(RegionNames.ContentRegion, typeof(Overview));

            var regionmanager = Container.Resolve<IRegionManager>();
            regionmanager.RegisterViewWithRegion(RegionNames.ContentRegion, typeof(PersonDetails));
            regionmanager.RegisterViewWithRegion(RegionNames.ContentRegion, typeof(Overview));

and PersonDetails is showed. When I run

            RegionManager.Regions[RegionNames.ContentRegion].Activate(typeof(Overview));

            RegionManager.Regions[RegionNames.ContentRegion].Activate(typeof(Overview));

I get an error

This RegionManager does not contain a Region with the name

This RegionManager does not contain a Region with the name

When I exchange "RegisterViewWithRegion" by "AddToRegion" I get another exception. What's wrong here?

❔ Get an entity with Sql data client

Hi, Im trying to read some data with the sql data client and Im stuck. The data looks like this: ID (uniqueidentifer, PK), Forename (nvarchar), Lastname (nvarchar), Birthday (datetime) The code looks like this

❔ Exclude sql from build

Hi, how can I exclude some files from the compile process? Imagine I have script like

CREATE DATABASE @name

CREATE DATABASE @name

and VS complains about the syntax near '@name'. Whatever, I know it better and want VS stop to care about these files, just have them in a *.resx file for now. I already set the build step to "None" but VS doesnt care... is this a bug?

❔ Load *.sql files (How to handle them?)

Hi, Im creating a backend in NET Core and I do not want to use EF Core as I need to extend my SQL knowledge, so I thought it's good to use SqlDataClient and raw SQL. So far so good. My solution structure is like this: - Domain (contains Models and SQL scripts) - Infrastructure (contains Repositories, Services, SQLManager [classes to create database, tables, call sql scripts, etc) - Web API (controllers that use the services in the infrastructure) My idea was to store the SQL scripts along the models as resource files and have them in a *.resx file or maybe call the files programmatically, but I think the first option is good for resolving compile errors. I wonder if I can reference the *.resx files from another project (infrastructure)? How do you typically deal with *.sql files that you call in your programs?

Map complex object (dictionary) from appsettings.json to model

Hi, i have a complex appsettings.json like this

"interceptor": {
    "interactionType": "redirect",
    "protectedResourceMap": [
      ["https://graph.microsoft.com/v1.0/me", ["user.read"]]
    ]
}

"interceptor": {
    "interactionType": "redirect",
    "protectedResourceMap": [
      ["https://graph.microsoft.com/v1.0/me", ["user.read"]]
    ]
}

How can I map this? I have a class definition

public class MSAL 
{
  public MSALInterceptorConfig Interceptor { get; set; }
}

public class MSALInterceptorConfig
{
  public string? InteractionType { get; set; }
  public List<Dictionary<string, List<string>>>? ProtectedResourceMap { get; set; }
}

public class MSAL 
{
  public MSALInterceptorConfig Interceptor { get; set; }
}

public class MSALInterceptorConfig
{
  public string? InteractionType { get; set; }
  public List<Dictionary<string, List<string>>>? ProtectedResourceMap { get; set; }
}

and read the config like

var builder = WebApplication.CreateBuilder(args);
var config = builder.Configuration;
var clientConfig = config.Get<MSAL>();

var builder = WebApplication.CreateBuilder(args);
var config = builder.Configuration;
var clientConfig = config.Get<MSAL>();

When I check the clientConfig object, I see that the ProtectedResourceMap has one entry: key="1" and value="user.read". How can I fix it so I have a list of dictionary entries?
