ClassLibrary | Some helpful classes | Reflection library

Recently I am updating my self to learn this new technology, however I cannot get the source generator running even I followed step-by-step to tutorial.

What I have done:

1. Create a solusion with a console application, then add a class library project. Both projects are .NET 5.

2. Install NuGet package Microsoft.CodeAnalysis.CSharp.Workspaces for both projects.

3. In the class library project, write following code:

   ...

When I publish a ASP.NET MVC Core 3.1 application, the logs of exceptions contain the path of the developers machine.

Example of a log:

Completely new to coding and thought I had a good chunk down before this issue. I want to save a new record to sql but trying to capture the id of a chosen item from another table. Thought I could use the same foreach structure I did when I was capturing a list of data, but this is of a single record in a combobox. What am I doing wrong here?

I'm trying to publish a WPF app with Target Framework net5.0-windows using ClickOnce (Built in VS2019), which has a Project Reference to another .NET5 Class Library.

But I always run into the following exception:

Publish has encountered an error.

Publish has encountered an error. We were unable to determine the cause of the error. Check the output log for more details.

The diagnostic log shows me the exact exception:

System.AggregateException: One or more errors occurred. ---> Microsoft.WebTools.Shared.Exceptions.WebToolsException: Publish has encountered an error. We were unable to determine the cause of the error. Check the output log for more details. --- End of inner exception stack trace ---

---> (Inner Exception #0) Microsoft.WebTools.Shared.Exceptions.WebToolsException: Publish has encountered an error. We were unable to determine the cause of the error. Check the output log for more details. <---

Microsoft.WebTools.Shared.Exceptions.WebToolsException: Publish has encountered an error. We were unable to determine the cause of the error. Check the output log for more details.

The issue can be easily reproduced:

1. Create new Solution with a WPF project (.NET5)
2. Create new Class Library (.NET5) in this solution
3. Reference the ClassLibrary from the WPF App
4. Try to publish the WPF App with ClickOnce (right-click the WPF App project -> Publish -> ClickOnce, ...)

Here's a Demo project, which I've created followed the steps above:

PublishDemo.Core (Class library)

Currently, I have an application that is built according to the clean architecture.

I have created one py script which imports my .netStandard classLibrary and runs its execution

The issue is, when my class library .netStandard version is 2.0 or less it runs properly, But if the version is .netStandard 2.1 it asks for netStandard.dll as not found.

Now i have copied the .netStandard file from 'C:\Program Files (x86)\dotnet\shared\Microsoft.NETCore.App\3.1.5' location and pasted with the Py script location and now it ran successfully.

I don't understand why specifically with .netStandard v2.1 the DLR with Iron python does not detect the netStandards dll. or are there are any steps i am missing?

Greeting all, firstly let me exclaim that I have scoured the existing questions to no avail.

Forgive me if I missed one that addresses this specific concern. This .NET Core 3.1 Web API uses another project a ClassLibrary in the solution to support its HTTP Verb methods. A class in the ClassLibrary is named Cars and it is inherited from ICars, probably just for default Dependency Injection purposes of .NET Core, but of course this is used (constructor injected) for the Controller CarController.

However there is another Controller BlueCarsController that uses a ClassLibrary BlueCars via its interface IBlueCars. Note the interfaces expose completely separate respectively distinct methods implemented in the respective classes.

My attempt to properly inject the inherited interface:

I am using Xamarin Forms with Prism.

How can I register a service for HttpClientFactory? Is there a equivalent in xamarin/prism to the ConfigureServices method in .net core?

I would like to use the equivalent of this code in Xamarin forms:

I downloaded the jsonUtils project from Github https://github.com/bladefist/JsonUtils

It consists of a website and classlibrary. The classlibrary has all the cool stuff I want in it.

I notice the top level folder of that solution contains Website, Classlibrary and Packages.

I built and run the the solution. Works great.

I copied the classlibrary to my own solution where I need the functionality and did Add New... Existing Project and it's sitting pretty there.

I can make calls, get results and everything is hunky-dory.

Now I checked this all into VSO (Azure) and downloaded it on my different PC.

It won't compile on this PC and there is a missing reference.

System.Data.Entity.Design.PluralizationServices.dll is not found.

So I gone back to the PC where it works and "show all files" and in the bin folder I can see the missing files.

What is the correct way to deal with this? One big difference is that I don't have the Packages folder containing the references that existing in the original github solution.
