我有一个WebApp，里面有一些WebApi 2，WebApp发布在运行IIS的服务器上。
当我向WebApp添加新内容时，更新工作正常，所有内容都正确提供，但现在我刚刚对现有API进行了更新，该API只是不返回任何内容，因为API仍然需要旧的参数。
我还试图删除以下网站的/Microsoft.NET/Framework & Framework64临时文件文件夹中该高速缓存文件，但它没有任何效果。
那么，如何强制IIS更新我的WebApp呢？
我修改的API方法如下：

<HttpPost()>
<Route("rc")>
Public Function RepartiCassa(<FromBody()> ByVal where As ModelConfig.Config) As IEnumerable(Of Reparti)
    Dim re = Request
    Dim headers = re.Headers
    Dim piva As String = ""

    If headers.Contains("authToken") Then
        Dim token As String = headers.GetValues("authToken").First()
        Dim data = TokenManager.Principals(TokenManager.GetPrincipal(token))
        If data Is Nothing Then Return New HttpResponseMessage(HttpStatusCode.Unauthorized)

        piva = data.piva
    End If

    Dim modelConfig As ModelConfig = New ModelConfig

    Dim rep As Reparti = New Reparti
    Return rep.TotaliRepCassa(where.data.inizio, where.data.fine, modelConfig.QueryParametri(where.config, "TRC", False), piva)
End Function

而在旧版本中则如下所示

<HttpPost()>
<Route("rc")>
Public Function RepartiCassa(<FromBody()> ByVal where As ModelConfig.Config) As IEnumerable(Of RepCassa)
    Dim re = Request
    Dim headers = re.Headers
    Dim piva As String = ""

    If headers.Contains("authToken") Then
        Dim token As String = headers.GetValues("authToken").First()
        Dim data = TokenManager.Principals(TokenManager.GetPrincipal(token))
        If data Is Nothing Then Return New HttpResponseMessage(HttpStatusCode.Unauthorized)

        piva = data.piva
    End If

    Dim modelConfig As ModelConfig = New ModelConfig

    Dim repCassa As RepCassa = New RepCassa
    Return repCassa.TotaliRepCassa(where.data.inizio, where.data.fine, modelConfig.QueryParametri(where.config, "TRC", False), piva)
End Function

所有的改变是RepCassa的模型变成Reparti
