CreateAuthorizeUrl Method Not Found

[SimonEvans482]

SDK you're using (please complete the following information):

• Version: Xero.NetStandard.OAuth2 - 9.2.0.
  Xero.NetStandard.OAuth2Client - 1.6.0
  IdentityModel - 7.0.0

Describe the bug
When attempting to authorise via Pkce, I am getting an exception on client.BuildLoginUriPkce(codeverifier), in:

    Public Function GetLoginURI() As String
        codeverifier = GetRandomString()
        Return client.BuildLoginUriPkce(codeverifier)
    End Function

Exception Text:

System.MissingMethodException: 'Method not found: 'System.String IdentityModel.Client.RequestUrlExtensions.CreateAuthorizeUrl(IdentityModel.Client.RequestUrl, System.String, System.String, System.String, System.String, System.String, System.String, System.String, System.String, System.String, System.String, System.String, System.String, System.String, System.Nullable1, System.String, System.String, IdentityModel.Client.Parameters)'.'`

To Reproduce
Steps to reproduce the behavior:

1. Initiate an instance of XeroClient with XeroConfiguration
2. generate a codeverifier string
3. call client.BuildLoginUriPkce(codeverifier)

Expected behavior
Pkce auth flow to run without exception

Screenshots
I don't think necessary

Additional context
Have been using the SDK for a number of years without issue. May have recently updated NuGet package to latest version. This may be a reoccurrence of ticket #384

Thanks for raising an issue, a ticket has been created to track your request

downgrading IdentityModel to 6.2.0 does resolve the issue, so presume version 7.0.0 support just needs to be added...

This is the same as issue: #554

Is there any news on whether this problem will be fixed?

[itlpierre]

Issue appears to be with Xero.NetStandard.OAuth2.Client. According to #520 a fixed was pushed to version 9.2 of Xero.NetStandard.OAuth2 but the issue was closed without addressing Xero.NetStandard.OAuth2.Client
