When we add the reference, we are able to use the .netstandard libs classes in our .net core console project (in Visual Studio), and it compiles.
When we run the app, it immediately crashes with this error in the output window:
An unhandled exception of type 'System.IO.FileNotFoundException'
occurred in Unknown Module. Could not load file or assembly
'MyNetStandard20Assembly, Version=0.1.0.0, Culture=en-us,
PublicKeyToken=null'. The system cannot find the file specified.
Update / Cause (still looking for reason)
So we use AssemblyInfo files in our projects and in order to make these work with the new project structure we needed to add this to the first PropertyGroup in the .NET Standard project:
<GenerateAssemblyInfo>false</GenerateAssemblyInfo>
That then allows us to have a Properties/AssemblyInfo.cs file in the project, just like a .NET Framework project would allow.
Anyway, when we remove this from the .NET Standard project then the .NET Core project finds the assembly and is happy.
Does anyone know why?

I have existing app that uses MySQL Server. Some errors I was getting when trying to add a new feature led me to upgrading to 'MySql.Data.EntityFramework 8.0.11'.
error I am getting when on:
public CitiesContext() : base("name=CitiesContext"):
An error occurred creating the configuration section handler for entityFramework: Could not load file or assembly 'EntityFramework, Version=4.6.1.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
Under my properties, my target framework is still version 4.6.1.
Is there a 'how to document' somewhere on how to upgrade the EntityFrame work? I know several of the other installed packages were installed while targeting v 4.6.1, so lots of other types of errors using (like hay this was compiled with v 4.6) when trying to compile with a web.congf using
I have installed
PM> Install-Package EntityFramework -Version 6.4.4
Package 'EntityFramework.6.4.4' already exists in project 'Lat34North'
Time Elapsed: 00:00:00.0186347
Please note. This is a hobby for me, not a profession. The app is written using asp.net mvs an first issued in 2018. Do I just need to change the target in the properties and upgrade all the other packages??
Thank you for any help.
I'm trying to get the Codeunit 50000 in this zip file to work: https://kappiwebhosting.blob.core.windows.net/dynamcisis/2015/09/Json.zip
Found here: https://dynamics.is/?p=2303

I'm trying to get Dynamics Nav 2009 to recognize the NewtonSoft.Json.dll, but no matter which version i try, i get this error as soon i want to verify the DotNet variable "JsonTextReader"/"JsonTextWriter" when selecting the subtype.
.NET interop: exception occured, 'Could not load file or assembly 'Newtonsoft.Json, Version=4.5.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.'.
If i declare a new Test variable of type DonNet and click [...] to select it from scratch i got this error when trying to choose which assembly to use:
.NET interop: exception occured, 'Could not load file or assembly 'C:\Program Files (x86)\Microsoft Dynamics NAV\60\Classic\Add-ins\Newtonsoft.Json.dll' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.'.
The Newtonsoft.Json.dll file is present ind the folder, and "Everyone" have full control to the folder as well as the file.
The Json.zip file contain a single Newtonsoft.Json.dll which i started out with. Same error. The i downloaded the https://github.com/JamesNK/Newtonsoft.Json/releases and tried all versions with the same result.
Why all this? Yes, the company i work for have decided to start using Shopify, and i need to write an interface for getting orders from Shopify etc.
I really cannot figure out why i can't get this to work. There are 3 other DotNet "variables" that's configured and works as intended with no errors.
So any advice is highly appreciated.
Thanx
Looking for help for some solutions on switching out the default data provider for the project from MS SQL to mySQL. Eventually with the intent of deploying the solution to Auruora on AWS.
After installing the nuget package I get something along the lines of :
System.TypeLoadException: Method 'Clone' in type 'MySql.Data.EntityFrameworkCore.Infraestructure.MySQLOptionsExtension' from assembly 'MySql.Data.EntityFrameworkCore, Version=6.10.5.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d' does not have an implementation.
This lead me to believe that there is no .NET 2.0 Entity Framework Core extention that runs for MySQL. Do I have to rollback to a different version?
For EntityFrameworkCore, it's suggested to use Pomelo.EntityFrameworkCore.MySql.
You may refer to their Getting Started documentation.
A fellow member of the community has kindly summarised the essential steps here:
Put Pomelo.EntityFrameworkCore.MySql into the xxx.EntityFrameworkCore project's .csproj file (see step 2 in the Pomelo getting started guide)
In your xxxDbContextConfigurer class put builder.UseMySql(...) rather than builder.UseSqlServer(...)
Change the connection string found in the appsettings.json file in the xxx.Web.Host project
I have a weird problem here. I'm trying to access a MySql database with Entity Framework Core.
It works on the .NET console. but when the same code runs on the web app it says.
fail: Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware[0]
An unhandled exception has occurred while executing the request
System.TypeLoadException: Method 'Clone' in type 'MySQL.Data.EntityFrameworkCore.Infraestructure.Internal.MySQLOptionsExtension' from assembly 'MySql.Data.EntityFrameworkCore, Version=8.0.9.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d' does not have an implementation.
at Microsoft.EntityFrameworkCore.MySQLDbContextOptionsExtensions.UseMySQL[TContext]
at ConsoleApplication.EmployeesContextFactory.Create(String connectionString) in BooksController.cs:line 65
Here is my code
var optionsBuilder = new DbContextOptionsBuilder<EmployeesContext>();
optionsBuilder.UseMySQL(connectionString);
var context = new EmployeesContext(optionsBuilder.Options);
context.Database.EnsureCreated();
It gives me the exception on the method UseMySql() The same exact code works fine in the console.
Also connectionString, .NET Core version and many of the constraints that I can think of are the same.
EDIT
Seeing the difference The ASP.NET project has following Nugets
The console app has the following,
Both projects show it's target framework as 2.0
What's the right way to solve this issue?
Because the current MySQL connector only supports .NET Core 1, you might not be able to use it with v2.
You could try this package at https://github.com/jasonsturges/mysql-dotnet-core
I hope someone can answer this as its driving me crazy. I have installed Monodevelop on windows XP. The version being 2.8.6.5. I set the default/active runtime as Microsoft .Net and set my projects to target .net 4.0 via project settings BUILD-->General->Target framework.
When I debug it from the application output window it loads XSP 2.0 and tries to the old .Net 2 DLL's ie from the .Net 2 GAC - C:\windows\assembly instead of the .Net 4 GAC.
when I debug setting Mono as the active runtime it works ok.
I get the error, which is understandable given the fact the build is targeting .Net 4 yet its looking at the wrong runtime:
Could not load file or assembly 'TestWeb' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.
