Hello Community,
I am a starter with c# but played around with it and created a windows forms program using the designer to create the GUI. This worked pretty well but suddenly, after adding 2 radio buttons, and recompiling I received tons of strange errors like "invalid token { ..." pointing to part in the code where I did not change anything.
I think somehow some "includings" required for the forms are missing since I also am not able anymore to open the design tab. The design tab simply vanished!
It is also strange that if I open the project again the view looks different, it shows an app.config file first whith not much inside
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<startup>
<supportedRuntime version="v4.0"sku=".NETFramework,Version=v4.0" />
</startup>
</configuration>
I experienced the same behaviour some weeks ago and now again.
I have an older copy of the project (unfortunaltey I do not use source code version management so far) and if I load this it looks good (with the design tab). So I need to redo my changes from this last save and should be able to work again. Not nice but should be ok.
But anyhow I would be interested to know why this happened, how to prevent that this happens again and If i can repair it somehow? Any ideas?
Thank you
Michael
