Hi,
i am writing a Visual Studio Extension and I need to get the OutputFileName or TargetFileName for C++ projects in the solution. For example in a sample solution this OutputFileName or TargetFileName would be ConsoleApplication.dll(note that its case sensitive). I wrote some code as shown below to achieve this but my code is crashing in the lines below. The only line that works is when i try to get Output Path. OutputFileName crashes in both cases as shown in code below. I also tried to cast it to a VCProject using Microsoft.VisualStudio.VCProjectEngine using the external dll but I dont know how to get the OutputFileName or TargetFileName nor do I not know if its going to work.

Examples on the internet show below should work. However it is not working. As I said OutputPath works. Is this because its an unmanaged C++ project and I have to get the path using some other way? I can confirm the projects i am working with are valid C++ unmanaged projects.

EnvDTE.DTE dte2 = Package.GetGlobalService(typeof(DTE)) as DTE;
          Projects projects2 = dte2.Solution.Projects;
string outputPath = projects2 [0].ConfigurationManager.ActiveConfiguration.Properties.Item("OutputPath").Value.ToString(); //This works
        string outputFileName = projects2 [0].ConfigurationManager.ActiveConfiguration.Properties.Item("OutputFileName").Value.ToString(); //This crashes

       string outputFileName = list[0].Properties.Item("OutputFileName").Value.ToString();//This crashes

What I have tried:

string outputFileName = projects2 [0].ConfigurationManager.ActiveConfiguration.Properties.Item("OutputFileName").Value.ToString(); //This crashes

 string outputFileName = list[0].Properties.Item("OutputFileName").Value.ToString();//This crashes

VCProject vcproject = list[0].Object as VCProject;//How to use this?
