I am working on using EPPlus C# assembly for Excel from PowerBuilder. I am doing it with PB 2021 for now until we move to PB 2019-R3. Then I can move the code into the main application.

I wrote a wrapper assembly in C# to make it easier to work with from PowerBuilder. Works great except for one problem.

The assembly becomes locked after using it. I have to exit PowerBuilder before I can copy the newest DLL into the folder where my PB app loads it.

Is this a bug or am I missing something?

Same here and I think it was reported quite some time ago.

Hi Roland / Tim;

  Are you using  ...

For example: lnv_Assembly.LoadWithDotNetFramework ("<MyDotNet>.dll", true)

Regards .. Chris

That's only for .NET Framework binaries. I believe I submitted an enhancement request asking for the same parameter to be added to LoadWithDotNet

We were on an early version of 2019 so ended up making the wrapper COM aware and calling it that way. We skipped over 2019-R3 and moved to 2022 but didn't update the code.

I don't remember. I haven't had to touch this code since and this is the only C# we are using from PB.

Hi Roland,

This is a known issue. I suggest you submit a support ticket about this so it can be properly tracked.

Regards,
