Visual Studio Code C# - Error MSB4062

[DGutierrez3]

Hello everyone, some time ago I am trying to develop a plugin for Notepad++. But unfortunately without much success.
Before giving up I would like to share my problem with you. Maybe they can give me a hand.

My goal is to develop it with Visual Studio Code in C#. As a basis for may project I have downloaded the following Pack NotepadPlusPlusPluginPack.Net (I don´t know if there is a more updated version).

However, when I complie the project I get the following error :

How can i solve this error?

Iteresting is that the *.dll Library is generated. However this is not compatible with Notepad++

The same question (with some extra details) I have posted in Stackoverflow.

I would be happy receive any questions, suggestions or comments.
Many thanks!

If you get back that this is an ANSI version then the call to IsUnicode does not return True.

@DGutierrez3

And since your plugin contains that function, you should be easily able to set it to return true!

@Ekopalypse And just an FYI this error message from Notepad++ is a little too general. It usually isnt specific just for that function (though it is possible I guess), but at least it does indicate something is wrong with the DLL such as not having the correct symbols exported.

@dail - thank you.

@DGutierrez3
to make sure that the functions are exported you can use
a visual studio command prompt and call dumpbin /exports YOUR_PLUGIN.dll

something like

dumpbin /exports PySnack.dll

Forget about the PyInit_Npp, this is specific to my plugin but
the other 6 must be there.

That might have been better as a “black” code box, as I was about to ask where to see PyInit_Npp

Only almost just before posting did I notice the scroll bar on the far right. :-)

Good info, though; I guess we all learned something.

Your definitely correct.

i face the exact same issue you mention on top when i migrate my development environment to new PC with fresh intallation of visual studio. 1st i thought would be due to newer version of visual studio but its not.

later on i found the solution for this, not sure if you still need it, keep a record here in case anyone else face the same issue.

Solution:
this was due to missing .net framework 3.5, just need to manually install .net framework 3.5 solve my compilation issue. Guess .net 3.5 only come with VS 2015 or older, VS 2017 onwards come with newer .net framework
