[mapserver-users] csharp_mapscript dotnet core on Linux

[ruigis]

I finally made it. After editing a couple of swig templates I managed to
compile the mapscript_csharp and use it from dotnet core 2.2

Here is the commit with a bunch of changes:
https://github.com/3x0dv5/mapserver/commit/61164981367899632006918b757c6a553cad1f02

Now the thing is that probably most of what I did was probably not needed,
but maybe it is actually useful for the project. So if someone could take a
quick look and see what could be used.

My process to compile:
1. git clone of master
2. mkdir build
3. cd build
4. cmake -DCMAKE_INSTALL_PREFIX=/opt \
       
-DCMAKE_PREFIX_PATH=/usr/lib/x86_64-linux-gnu:/usr/share/postgresql/10:/usr/local:/opt
\
        -DWITH_CLIENT_WFS=ON \
        -DWITH_CLIENT_WMS=ON \
        -DWITH_CURL=ON \
        -DWITH_SOS=ON \
        -DWITH_PHP=OFF \
        -DWITH_PERL=OFF \
        -DWITH_RUBY=OFF \
        -DWITH_JAVA=OFF \
        -DWITH_CSHARP=ON \
        -DWITH_PYTHON=OFF \
        -DWITH_SVGCAIRO=OFF \
        -DWITH_ORACLESPATIAL=OFF \
        -DWITH_MSSQL2008=OFF \
        ../ >../configure.out.txt
5. at this point there is still one small issue with the code generated by
SWIG:
the file: build/mapscript/csharp/mapscriptPINVOKE.cs 
has the following duplicated, I needed to delete one
static mapscriptPINVOKE() {
  }

6. make all
7. open Jetbrains Rider and create a sample console project and add
reference to the mapscript_csharp.dll also add the PATH where mapscript.so
is or copy it to the /bin/Debug/netcoreapp2.2/


My sample output:
