Can i use Dynamic Expression<Func<,>> as MinimalApi Delegate?

how can i generate delegate for minimalAPI delegates in asp.net core?

It’s unclear what you want to do but if you compile the expression it should work.

[sajjadarashhh]

@davidfowl when we Compile LambdaExpressions that have another parameter that isnt show us and that have'nt name and type of that is : 'Closure'
and that is'nt have name

Can you write a minimal example of what you are trying to do and shows what doesn’t work? It might be some detail of the generated delegate that makes it not work well.

Ah I think you’re saying that the parameter info for generated delegates don’t have a name. Yep that’s a problem for minimal APIs. There’s also no way to apply attributes to the parameters using expression tree APIs.

You might need to open up an issue on dotnet/runtime with this scenario.

Tats not very hard to try it just you need to this for your delegates
((Expression<Func<int,int>>)Input=>input)).Compile()
Thats not working to set for delegate argument

Can you share a real example of what you're trying to do?
