• I have web application project in Vb.Net
• I want to add web API to my project
• Visual studio 2019 with .Net 4.7.2

but when I run the application it throws an error :

Line 27: Line 28: ' Code that runs on application startup
Line 29: GlobalConfiguration.Configuration(AddressOf AppStart.WebApiConfig.Register) Line 30:
''GlobalConfiguration.Configuration(Register)

output :

This compiler is provided as part of the Microsoft (R) .NET Framework, but only supports language versions up to Visual Basic 2012, which is no longer the latest version.

    GlobalConfiguration.Configuration(AddressOf AppStart.WebApiConfig.Register)

I've downloaded all the packages from nuget:

• Microsoft.asp.net.wabapi
• Microsoft.asp.net.wabapi.clinet
• Microsoft.asp.net.wabapi.Core
• Microsoft.asp.net.wabapi.selfHost

        GlobalConfiguration.Configuration(AddressOf AppStart.WebApiConfig.Register)

webconfig

<system.webServer>
      <validation validateIntegratedModeConfiguration="false" />
      <handlers>

        <!--webapi-->
        <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
        <remove name="OPTIONSVerbHandler" />
        <remove name="TRACEVerbHandler" />
        <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
        <!-- end web api -->

</handlers>
<system.webServer>

The only thing I did was to update the web.config:

<?xml version="1.0" encoding="utf-8"?>
<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">

by removing xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0"

<?xml version="1.0" encoding="utf-8"?>
<configuration>

It looks like this line led to this error:

which is no longer the latest version.
