'msbuild' is not recognized as an internal or external command,
operable program or batch file.
Please try this.
a) Go to pcf project folder from cmd line & run
msbuild /t:restore
b) Go to cds project folder from cmd line & run
msbuild /t:restore
c) On cds project folder, run
msbuild
Note: If you have added, pcfproj as add-reference to cdsproj, step 3 would build both of them & create a solution contaning controls.
Hope this helps.
