I am getting an error on the very first line of code in the App.cs
file (which is creating a readonly variable). The error I am getting is:
A first chance exception of type 'System.TypeInitializationException' occurred in PresentationFramework.dll An unhandled exception of type 'System.TypeInitializationException' occurred in PresentationFramework.dll Additional information: The type initializer for 'System.Windows.Application' threw an exception.
This is the message popup I get in VS:
An unhandled exception of type 'System.TypeInitializationException' occurred in PresentationFramework.dll
Additional information: The type initializer for 'System.Windows.Application' threw an exception.
The only change I have made is adding this to my app.config
:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.1"/>
</startup>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
</configSections>
<log4net>
<appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender" >
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%ndc] - %message%newline" />
</layout>
</appender>
<root>
<level value="INFO" />
<appender-ref ref="ConsoleAppender" />
</root>
</log4net>
</configuration>
The issue was that I had the <startup>
xml node in the app.config
file at the start rather than the end of the file. It needs to be the last thing in the app.config
file.
<?xml version="1.0" encoding="utf-8"?>
<configuration>
// lots of other stuff here...
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.1"/>
</startup>
</configuration>
