VS2010, C# compiler error caused by passing default string parameter to attribute

[Tirael]

Error in VS2010 - "An attribute argument must be a constant expression, typeof expression or array creation expression of an attribute parameter type" , project UnitsNet.net35.
If I changed in attributes.cs default value of parameter pluralname from null to "", this project successfully compiled.

Thanks for reporting this, I am only using VS2012 and 2013. Apparently this is a bug in the VS2010 compiler.

I just pushed a workaround as described in the first link:
string pluralName = (string)null

I don't have VS2010 so it would be great if you could report if that fixes the problem.

Did not intend to automatically close this by the commit.
