Thanks Markov,

Please keep me posted, I’m not certain when we need to demo possible solutions to management but I’d like to include this tool because I think it would be a good, competitive option if we can get it to work for our purposes.

Hi Markov,

I’m deserializing a static json file using the below data structure, the gantt chart renders until it gets to a task that has planned dates and then it generates an exception. I’m using Smart.Blazor 20.0.4 and .NET 8

JSON:
