Authorize new user

[traponto]

I'm having trouble activating the authorize procedure inside my WinForm application, it seems that the 'GetToken' function is not invoked and the program goes in loop in the 'Authorize' procedure. I took the same instructions in the sample application 'DiscogsAuthenticationConsole' where instead everything is fine.

Well, It is very hard to diagnostic anything from what you describe. I would say since DiscogsAuthenticationConsole is working try to simplify your code to make it more and more similar to the sample application till it works.

Sounds like you need to synchronize your UI thread context.

@FrancisChung DiscogsClent is (and needs to be) agnostic in term of application context (WPF, or WinForm or console, or ASP etc...). So it is the caller responsability to make sure that the API is called on the "context" context.

I am relatively new to c #. In my WinForm application I used the same code I found in your console application example: var oAuthConsumerInformation = new OAuthConsumerInformation("X", "Y"); var discogsClient = new DiscogsAuthentifierClient(oAuthConsumerInformation); var aouth = discogsClient.Authorize(s => Task.FromResult(GetToken(s))).Result; In the console application the GetToken function is called, instead the Authorize method seems that never come back in the WinForm App. I did a debugging session to see what happens inside the Authorize method and I found that in the RestSharpHelper: public async Task<OAuthTokenInformation> GetTokenInformationFromRequest(IRestClient client, string relativeUrl) { var request = new RestRequest(relativeUrl, Method.POST); var response = await client.ExecuteTaskAsync(request); return !CheckResponse(response) ? null : GetTokenInformationFromBodyResponse(response); } ...the ExecuteTaskAsync method never end when executed inside the WinForm App.

Thank you for your answers and for the suggestions you gave me. I took a look at the stackoverflow link (as FrancisChung suggested) and I think I fall into the "deadlock" case described there by "Daniel". I tried to insert the 'Authorize' procedure in a separate thread and I verified that it works. However, I would like to be able to manage the Key (provided by DiscoGS) and tokens (provided by DiscoGSClient) within my WinForm application, so any suggestions to do this are welcome.

@David-Desmaisons My comments were meant to be directed at Traponto's code, not yours. Apologies for the miscommunication. And you're absolutely right about APIs needing to be context neutral.
