I have just updated my subscription and updated my licence using the licence viewer to get a code. I enter this code into application.xaml.cs
eg ArcGISRuntime.SetLicense("runtimebasic,101,xxx1234567890,dd-mon-YYYY,ABCDE1234567890");
After doing this I still get an error " License error with ArcGISruntime. The ArcGISRuntime SDK development licence has expired, please renew the developer license."
I can create a new projects, they don't have the error. Just projects that were using the old licence.
Any idea how to make my existing project use the new licence?
