And shouldn't it be unimportant which .NET language is used? If I look through the .NET docs I can decide if I'd like to see the stuff in VB.Net, C# or C++. So if you know C++ why shouldn't you use "managed C++"?</p>

<p>Is it possible to assign a blank string (i.e. "") as a Default Value in the Entity Framework's EDMX designer? The only technique I've found is to edit the edmx file manually using a text editor</p>
| <p>I realize that this is an extremely old question, but for posterity's sake, in the EF4 designer you can type a space in the properties window field, then hit backspace, leaving the field empty instead of the default value of (None). For strings, this seems to default to String.Empty.</p>
| <p>Yes, the only way that I've found to set an empty string as the default value is to edit the EDMX. Editing the designer file doesn't work as the code is regenerated.</p>
