问题 I am developing a .NET Standard library and plan to use it in both .NET Core and .NET Framework projects. My library is dependant on a third library which itself is dependant on a few C binary files. The C binary files have to be copied to the output directory of the project which will be referencing my library. I added the binary files to my library project as content and they are copied to the content and contentFiles directories when the NuGet package is packed with the dotnet pack command

问题 I'm porting a console app to .NET core which load types from external libraries. In full .NET Framework using Type.GetType("typename, assemblyname") works when the assembly is located in the same folder that executable. In .NET Core, it returns null, wherever I place the library. As a workaround I've installed the System.Runtime.Loader package and attached to Resolving event to force the loading from a full path: AssemblyLoadContext.Default.Resolving += Default_Resolving; type = Type.GetType

Container.MyDataSet.ToList(); produces the following exception : "System.NotSupportedException : This target framework

问题 I've loaded an external DLL into your project like this Dim assembly As Assembly = Assembly.LoadFile(libraryPath & "filename.dll") Dim type As Type = assembly.[GetType]("NameSpace.ClassName") // i'm loading as a form here but can be any control Dim frm As Form = TryCast(Activator.CreateInstance(type), Form) What are the best practices if you're loading a class or a control inside the loaded form (above) that resides also inside the same assembly ? for instance: Lets say you loaded an assembly

问题 I'm really stuck and need some help. I have a .NET Core 3.1 WPF application, which decodes basketball scoreboard data and now I need to send this data over to .html file.

One of the requirements is that I have to be able to start and
