I've instaled adomd.net
I can connect with local cube :
AdomdConnection conn=new AdomdConnection();

connection.ConnectionString = "DATASOURCE='c:\\cube.cub'";

but I can't create local cube.

I tried :

string s= "DATASOURCE=C:\\MySales2.cub;" +

"SOURCE_DSN=\"Provider=MSOLAP;DATA SOURCE=LOCAL;INITIAL CATALOG=FoodMart
2000\";"

"CREATECUBE=\"CREATE CUBE MySales(" +

" DIMENSION Time TYPE TIME," +

" LEVEL Year TYPE YEAR," +

" DIMENSION Product," +

" LEVEL [All Products] TYPE All," +

" LEVEL [Product Family]," +

" LEVEL [Product Department]," +

" MEASURE [Unit Sales] Function SUM)\";" +

"INSERTINTO=\"INSERT INTO MySales(" +

" Time.Year," +

" Product.[Product Family]," +

" Product.[Product Department]," +

" Measures.[Unit Sales])" +

" SELECT " +

" Sales.[Time:Year]," +

" Sales.[Product:Product Family]," +

" Sales.[Product:Product Department]," +

" Sales.[measures:Unit Sales]" +

" FROM Sales" +

" WHERE Sales.[Time:year]='1997'\"";

AdomdConnection conn=new AdomdConnection();

AdomdConnection.ConnectionString=s;

AdomdConnection.Open();

This connection string works with com adomd but in adomd.net I got
ErrorCode -2147217805.
