Method not found Void Microsoft PowerBI Api V2 PowerBIClient ctor - Power BI Embedded

0 votes

 have a problem with Power BI Embedded. I want to embed a power BI report in a partial view. Following the guide, I created these methods on my controller:

public ActionResult Report()
    {
        credential = new UserCredential(username, passwordPowerBI);
        Authorize().Wait();

        ReportEmbed myReport = new ReportEmbed();

        using (var client = new PowerBIClient(new Uri(apiUrl), tokenCredentials))
        {
            EmbedToken embedToken = client.Reports.GenerateTokenInGroup(groupId, reportID, new GenerateTokenRequest(accessLevel: "View"));
            Report report = client.Reports.GetReportInGroup(groupId, reportID);

            myReport.reportID = reportID;
            myReport.embedURL = report.EmbedUrl;
            myReport.embedToken = embedToken.Token;
        }
        return PartialView(myReport);
    }

    private static Task Authorize()
    {
        return Task.Run(async () => {
            authenticationResult = null;
            tokenCredentials = null;
            var authenticationContext = new AuthenticationContext(authorityUrl);

            authenticationResult = await authenticationContext.AcquireTokenAsync(resourceUrl, clientID, credential);

            if (authenticationResult != null)
            {
                tokenCredentials = new TokenCredentials(authenticationResult.AccessToken, "Bearer");
            }
        });
    }

And in the view I just try to view my report. But the application go to this exception:

enter image description here

(sorry, some text is in italian. "Impossibile trovare il metodo" means "Method not found").

What is the problem? Something is missing in the web.config?

There appears to be a version difference between the assemblies. It detects the proper assembly at compile time, but it loads an older version of the client at run time. Make sure you're using the correct assemblies in your deployment.
