# Enable OWIN Logging in .NET Framework
|
|
|
|
The following code snippet shows how to enable Microsoft.OWIN logging in ASP.NET. OWIN logging is mostly useful for debugging issues relating to user sign in / flow, especially when using external identity providers such as Google, Facebook, etc.
|
|
|
|
To enable OWIN logging, add the following to your `web.config` file inside the `<configuration>` element:
|
|
|
|
```xml
|
|
<system.diagnostics>
|
|
<switches>
|
|
<add name="Microsoft.Owin" value="Verbose" />
|
|
</switches>
|
|
<trace autoflush="true" />
|
|
<sources>
|
|
<source name="Microsoft.Owin">
|
|
<listeners>
|
|
<add name="console" />
|
|
</listeners>
|
|
</source>
|
|
<source name="Microsoft.Owin">
|
|
<listeners>
|
|
<add name="file"
|
|
type="System.Diagnostics.TextWriterTraceListener"
|
|
initializeData="traces-Owin.log"
|
|
/>
|
|
</listeners>
|
|
</source>
|
|
</sources>
|
|
</system.diagnostics>
|
|
```
