Hello everyone,

I need your help in someting,
I am now developing a software that will be using c#.net and my sql database,

considering that i come from embedded system background, i build a software for a certain target in a layered architecture(MCAL - HAL - ..) and the C code must be complying with misra rules,

I was wondering if there is a best practice or standard I should be following when creating software in C#.net

Thank you,
