Thanks

Could you please point me to the relevant scripts?

I have checked and the three .csproj projects that you listed are NOT currently being build by the build scripts - because they are not needed for the test scripts. You will need to build them yourself.

The first question that I would ask is what are you trying to achieve?

DBUILD_APPS=ON will build the standard GDAL apps but does not affect the C# trial apps. I think this is the default anyway

DBUILD_CSHARP_BINDINGS=ON will build the c# bindings and the c# trial apps. If that is what you are trying to do this should be sufficient.

The directory structure is actually dependent on what is created by `dotnet` and can vary a little between platforms but sounds about right.

I have a feeling that when we went to cmake builds, the three apps you mentioned mighted have been removed from the build scripts since they are not used by the test scripts. I will check but, since they are csproj projects you should anyway be able to just build them on top of the bindings using `dotnet`.

Hi

I am building GDAL Master branch (https://github.com/OSGeo/gdal/tree/master/swig/csharp/apps) using CMAKE. I am using below flags to build the CSHARP Bindings

<arg value="-DBUILD_CSHARP_BINDINGS=ON"/>
<arg value="-DBUILD_APPS=ON"/>

However,


  1.
I notice that in "RelWithDebInfo" build mode there is NO "apps" folder generated in "RelWithDebInfo\swig\csharp" folder. I do see individual apps folder like "GDALCreateCopy", "GDALDatasetWrite", "GDALInfo" generated though. Is this expected?


  2.
I DO NOT see the any folder corresponding to GDALMemDataset , GDALDatasetRasterIOEx ,  VSIMem in my "RelWithDebInfo\swig\csharp" folder even though the source file is present at
https://github.com/OSGeo/gdal/blob/master/swig/csharp/apps/GDALMemDataset.cs
https://github.com/OSGeo/gdal/blob/master/swig/csharp/apps/GDALDatasetRasterIOEx.cs
https://github.com/OSGeo/gdal/blob/master/swig/csharp/apps/VSIMem.cs

Am I missing any additional CMAKE Flags. Can you please let me know?
