Loading data from NBR / ECB as plugins–part 11

Modified project – instead of one project that have the NBR and ECB exchange rates,I have now 4
1. Common interfaces / classes

2 NBR loading( first plugin)

3 ECB loading ( second plugin)

4 plugin loading project

 

Going to .NET Standard 2.1 and trying to load the NuGet https://github.com/natemcmaster/DotNetCorePlugins/blob/master/docs/what-are-shared-types.md .

Does not load. Going back to .NET Core 2.0  – some result.

RTFM – not supported .NET Standard  https://github.com/natemcmaster/DotNetCorePlugins/issues/24

So created a .NET Standard dll and changed from

<TargetFramework>netstandard2.0</TargetFramework>

to

<TargetFramework>netcoreapp3.0</TargetFramework>

Copied the code from https://github.com/natemcmaster/DotNetCorePlugins/blob/master/samples/hello-world/HostApp/Program.cs .

Loaded 0 plugins.

Put plugins in plugins directory – again 0 plugins.

Read the code copied – I must create separate folders for each plugin – makes sense, because we can have plugin diamond dependency – see here https://github.com/natemcmaster/DotNetCorePlugins/blob/master/docs/what-are-shared-types.md

Put in separate folder – error in this line

// This assumes the implementation of IPlugin has a parameterless constructor
var plugin = Activator.CreateInstance(pluginType) as BankGetExchange;

 

Apparently , this code does NOT mean to have a parameterless contructor – even if seems from the code


public class GetNBRExchange: BankGetExchange
{
private readonly HttpClient httpClient;

public GetNBRExchange(HttpMessageHandler handler = null)
{
if (handler != null)
httpClient = new HttpClient(handler, disposeHandler: false);
else
httpClient = new HttpClient();
}

 

So small modification to preserve tests and default code:


public class GetNBRExchange: BankGetExchange
{
private readonly HttpClient httpClient;
public GetNBRExchange() : this(null)
{

}
public GetNBRExchange(HttpMessageHandler handler)
{
if (handler != null)
httpClient = new HttpClient(handler, disposeHandler: false);
else
httpClient = new HttpClient();
}

Now it works …
