Warning 1 There was a mismatch between the processor architecture of the project being built "MSIL" and the processor architecture of the reference "PresentationCore", "x86". This mismatch may cause runtime failures. Please consider changing the targeted processor architecture of your project through the Configuration Manager so as to align the processor architectures between your project and references, or take a dependency on references with a processor architecture that matches the targeted processor architecture of your project.

Hello,

Thank you for the question.

This is a common warning message that appears in the NinjaTrader custom project while using Visual studio.

This message can safely be ignored along with all other Custom project specific warnings, only warnings or errors related to your custom code specifically should be noted.

I look forward to being of further assistance.
