Getting Parser Error On IIS with Default VS ASP.NET Sample RRS feed

  • Question

  • User-732303917 posted


    i'm getting a parser error when publishing my webservice on an server with windows 10.

    On the developer-Computer everything is fine.

    The VS Sample throuths the same exception:

     <%@ Application Codebehind="Global.asax.cs" Inherits="MeinTV.WebApiApplication" Language="C#" %>
    Microsoft .NET Framework-Version:4.0.30319; ASP.NET-Version:4.6.1590.0 

    The version of the Service is .NET 4.5. When i'm using 4.6 i will get the same Error.

    When running the Debug Site with IIS Express everything is fine, too.

    Hope someone can help me.

    Best regards

    Hi Nexder,

    You could open your IIS site in application pool and target the .net version to .net 4.5. This link provide the step on how to achieve this.


    Besides, please make sure you have have set the application pool .net CLR versionl to .Net CLR version v4.0.30319 and managed pipeline to integrated mode . All the application developed by net 4.0 and above are run in .net 4.0 CLR.

    Hi Yuk Ding,

    thanks for your answear.

    The DefaultAppPool already set to .Net CLR version v4.0.30319.
    Where is the different between DefaultPool and .NET4.5 Pool. Both points to .Net CLR version v4.0.30319

    A lokal IIS on my developer system runs fine. The config of both IIS systems looks identical.

    The IIS Express also works while Debugging. 

    The WebService Project Target is .NET 4.5 (.NET 4.6 has the same error)

    Best regards
