Problem while building the project.

[AnuragOval]

When I am building the project in vs 2017, the compiler throws error "Empty string not allowed for provider" Code: "1236" and section destinationdirs and sourcediskfiles is defined multiple times at line 5,12 and 27 respectively. Any suggestions will be helpful.

I get the following errors when building:

Sorry it took me so long to see this issue. It appears that Microsoft pushed an update to Visual Studio or the WDK that broke this project. At the moment, I don't have a suitable windows development environment to try and fix this problem, sorry.

One temporary solution might be to start a new WDK project using the latest version of the WDK and Visual Studio, and then copy the source files from this project into the new one manually.

@JaredWright, ok man, Happy New Year!
with all the difficulties I compiled. it seems to work, although it seemed to me at some point the network connections worked unstably or there was a partial blocking .. I will check it again, but I have one question - how do you not know how to block websites by URL?

@jenokizm: I had similiar errors like above while trying to compile it in an empty KMDF project in Visual Studio 2017. The simple solution was to include $(DDK_LIB_PATH)wdmsec.lib and $(DDK_LIB_PATH)fwpkclnt.lib in "Linker -> Input -> Additional Dependencies", afterwards it worked fine. Then it compiled fine on Windows 10 (but you need to use a correct WDK / SDK combination, too).

I got this also working with vs2019 at win10 and osr driver loader.
I could make pull request but I have no way to test older windows versions.
should I make it ?
perhaps a branch for vs2019+win10 ?

[JaredWright]

@apmattil I would gladly accept a pull request that brings this repository up to compatibility with VS2019 and win10! I would imagine that people will benefit more from having this repository compatible with a newer toolchain, than having this repository compatible with older toolchains.
