Open Source C to Arm using C#

Working on a project with a buddy of mine. We are trying to write a C compiler that handles custom op codes and one or two other things for a bigger project. To be totally honest, this is not my world. I am more comfortable higher up the abstraction tree, so I don't have all the details, but here is my best understanding of the problem. Because of how clang handles strings (storing them in separate memory addresses), we can't use the general C compiler, as it would cause major slowdowns down the line by orders of magnitude....

Hot Reload MAUI Error - Unable to build changes

When trying to use Hot Reload in my MAUI application on Windows, the moment I press the Hot Reload button while debugging I receive this error window. The same window also appears during debugging when a breakpoint is hit for the first time. I wasn't able to find a solution online and have not seen that window pop up anywhere else....

Service Agnostic API Wrapper Library Project Structuring

I've been developing a library for interacting with an API, and now that I've been developing it somewhat, I've realized that there's a few similar APIs that I'd like my library to interact with. One of these APIs has nearly identical endpoints, and for the identical endpoints, I was able to successfully deserialize the JSON using my existing JSONProperty annotations and Converters (although the responses are not fully 1:1). I was just wondering, how should I restructure the project in a way that users can select the API they want to use? If I were to make an interface (and have the library consumers select the concrete implementation), some of the APIs have endpoints that others lack....

Best solution to shared Web component in a WPF application

Hello everyone, I would like you expertise to know if I go in the good direction. I would like to develop a Web app (I think with a js framework) with a main component that will display data from an ASP Net API. however, I need to build a WPF application that will display the same component with the same retrieval logic. These two applications don't have the same purpose, the website will "build" the data and the WPF application will exported them to an external client application as a Plugin. Therefore, I need to be able to customize the buttons of my component according to my hosted application. To share this component, I thought about building it as a web component, hosted in my website : that way my website will use it easily and i thought about using a WebView2 in my WPF application that will download the web component in order to display it. Thank you a lot for yours answers !...

postgresql, efcore, fluent api mappings

Just started playing around with posgress and efcore. The type mapping for fluent api is different from sql server. The reference for mappings I believe is here: https://www.npgsql.org/doc/types/basic.html#write-mappings My main question is, when I'm writing .HasColumnType("") should follow the values in the column "PostgreSQL type"? or is "NpgsqlDbType" is valid too? meaning for nvarchar => .HasColumnType("character varying") or .HasColumnType("Varchar")...

Remember indent Method?

Trying to see if there is an existing solution. I am trying to print a paragraph of text in the terminal. The issue is i want the whole paragraph to be indented, at the same level instead of wrapping around and using the whole width it should wrap and start where the previous line started.
