C＃ASP.NET MVC PayPal未找到程序集

Question

我已經使用NuGet Install-Package PayPal

然后，我使用此處的代碼進行測試： https : //devtools-paypal.com/guide/pay_paypal

Dictionary<string, string> sdkConfig = new Dictionary<string, string>();
        sdkConfig.Add("mode", "sandbox");
        string accessToken = new OAuthTokenCredential("XXXXXXXXXXXXXXXXXXXXXX", "XXXXXXXXXXXXXXXXXXXXXX", sdkConfig).GetAccessToken();

我在此之后放置了一個斷點進行檢查，但是當我加載頁面時，我得到了：

Could not load file or assembly 'PayPal, Version=1.7.3.0, Culture=neutral, PublicKeyToken=5b4afc1ccaef40fb' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Assembly Load Trace: The following information can be helpful to determine why the assembly 'PayPal, Version=1.7.3.0, Culture=neutral, PublicKeyToken=5b4afc1ccaef40fb' could not be loaded.

對如何解決這個有幫助嗎？

我嘗試了從給出的可能重復項的鏈接中獲得的答案，但這些都不對我有用。

我剛剛將我的代碼復制到一個新的解決方案中，並且可以正常工作。 我唯一能想到的是，因為我將解決方案命名為“ PayPal”，這在某處引起了問題。
