I've published an ASP.NET Web API on IIS7 server. When I'm testing it locally. I get a framework error below:
Configuration Error
Description: An error occurred during the processing of a
configuration file required to service this request. Please review the
specific error details below and modify your configuration file
appropriately.Parser Error Message: The 'targetFramework' attribute in the
<compilation>
element of the Web.config file is used only to target
version 4.0 and later of the .NET Framework (for example,
'<compilation targetFramework="4.0">
'). The 'targetFramework'
attribute currently references a version that is later than the
installed version of the .NET Framework. Specify a valid target
version of the .NET Framework, or install the required version of the
.NET Framework.Source Error:
Line 20:
</appSettings>
Line 21:<system.web>
Line 22:<compilation targetFramework="4.5" />
Line 23:<httpRuntime targetFramework="4.5" />
Line 24:<authentication mode="None" />
I'm not quite sure what it is wrong as I have an ASP.NET website running on the server using framework 4.0.
