While working on an UWP app, I wanted to create a string.Format based value converter, so that I could provide a format string in the ConverterParameter , augment the data bound value with it and use the result as a key for a localized string from resources. When I tried to build the project however, I was met with the following cryptic error message:
|
1 2 3 |
Child node "2" exited prematurely. Shutting down. Diagnostic information may be found in files in the temporary files directory named MSBuild_*.failure.txt. |
Although the nor the error nor the generated diagnostic were too helpful, because I have mostly added just the new XAML binding, I suspected the error must be hidden there.
|
1 2 3 |
{Binding Converter={StaticResource TypeNameLocalizingConverter}, ConverterParameter={0}_Description} |
As you might expect, it is not possible to use curly brackets directly inside the XAML binding expression.
Solution is simple – escaping with backslash.
|
1 2 3 |
{Binding Converter={StaticResource TypeNameLocalizingConverter}, ConverterParameter=\{0\}_Description} |
With this little change, the code will compile and the value converter works as expected.
