Fatal Error C1092
You changed or added a data type since the last successful build.

Edit and Continue does not support the addition of new data types if a program database file, such as vcx0.pdb (where x is the major version of Visual C++ in use) is read-only. To add data types, the compiler must open the .pdb file in write mode.
