How to register class library create with .NET 6.0?

Question

I have a class library project create with .NET framework 4.7, and I use RegAsm.exe to register this library.
Recently I upgrade this project to .NET 6.0, and I can not found .net 6.0 version of "RegAsm.exe", so, what can I do?

Answer 1

As mentioned in https://learn.microsoft.com/en-us/dotnet/core/native-interop/expose-components-to-com in .NETCore you must use Regsvr32.exe.

@aluzi liu , I got into the same problem, did you manage to fix it with regsvr32 ?

Answer 3

Actually, if you use the new SDK style project file, then it is very easy to make/register COM.

In short, add <EnableComHosting>true</EnableComHosting> to <PropertyGroup>: this would create [ProjectName].comhost.dll file.
To register do: (/s is to suppress showing dialog)

<Target Name="PostBuild" AfterTargets="PostBuildEvent">

<Exec Command="regsvr32 /s $(TargetDir)$(ProjectName).comhost.dll" />

</Target>
