How to combine two variables directly in batch file?

Question

I am writing simple batch file as post-build action in Visual Studio and I cannot get rid of quotes which are added when I am combining two variables. The code looks like this:

set SolutionDir=%1
set ConfigurationName=%2

set AltSourceDir=%SolutionDir%\%ConfigurationName%

echo "%AltSourceDir%"

In the point of merge I get quotation marks:

""D:\WORK\Extractor\"\"Release""

How to merge them directly?

Answer 1

%~1 removes quotes. See call /?.
