I am trying to try DBLinq with the sqlite provider inside a simple ASP.NET web service. I am also using MonoDevelop 2.4 and Mono 2.6.7, The project in monodevelop references the DbLinq.dll which by default is set to be Local Copy. I can compile the webservice just fine. By when I try to run it from Monodevelop or using the xsp2 from the command line, xsp2 fails with a number of errors (see below). If I unchecked the Local Copy for the DBLinq.dll reference, xsp2 will execute but the Linq portion of the code does not work. This is also true for the MySQL provider. I think the problem is the when DbLinq is referenced and be locally copied, it also copies the dependent assemblies and one of the assembly is causing xsp2 to choke.<\/p>\n
Has anyone encountered this? How can I fix the problem or what is the workaround? Any help is very much appreciated. Below is the sample snippet of the webservice method in the asmx code behind.<\/p>\n
\n[WebMethod]
\npublic string getrecord() {<\/p>\nstring txt = string.Empty; \n\nusing( DataContext context = \n new DataContext(\"DbLinqProvider=Sqlite; Data Source=openemr.db\")) \n {\n var addrtbl = context.GetTable(); \n var addr = from a in addrtbl \n select a; \n foreach( var i in addr) \n { \n txt += i.City ; \n txt += \"; \"; \n } \n } \n<\/code><\/pre>\nreturn txt;
\n}<\/p>\n<\/blockquote>\nOf course, this might not be a good way to implement data access and will need to separate the concerns. But for testing purposes, this should at least work.<\/p>\n
Here is the error I get when I run xsp2. As I said above, one of the dependent assemblies that DbLinq references and copied locally is causing this to happen. My question is how do I best fix this so it works?<\/p>\n
