Yes you are right, you need WMF 3. but you can import solution with SDK.
Code from my Solution.
private void button1_Click(object sender, EventArgs e)
{
try
{
groupBox2.Enabled = false;
exportLabel.Text = "Please wait..";
String solutionUniqueName = nameLabel.Text;
QueryExpression querySampleSolution = new QueryExpression
{
EntityName = Solution.EntityLogicalName,
ColumnSet = new ColumnSet(new string[] { "publisherid", "installedon", "version", "versionnumber", "friendlyname", "uniquename" }),
Criteria = new FilterExpression()
};
querySampleSolution.Criteria.AddCondition("uniquename", ConditionOperator.Equal, solutionUniqueName);
Solution _solution = (Solution)this.service.RetrieveMultiple(querySampleSolution).Entities[0];
// Export or package a solution
//Export an a solution
String outputDir = pathTextBox.Text;
ExportSolutionRequest exportSolutionRequest = new ExportSolutionRequest();
exportSolutionRequest.Managed = false;
exportSolutionRequest.SolutionName = _solution.UniqueName;
if (packageComboBox.SelectedItem.ToString() == "Unmanaged")
{
exportSolutionRequest.Managed = false;
}
else
{
exportSolutionRequest.Managed = true;
}
ExportSolutionResponse exportSolutionResponse = (ExportSolutionResponse)this.service.Execute(exportSolutionRequest);
byte[] exportXml = exportSolutionResponse.ExportSolutionFile;
string manage = "";
if (exportSolutionRequest.Managed)
{
manage = "_managed";
}
else
{
manage = "_unmanaged";
}
string filename = _solution.UniqueName + "_" + _solution.Version + manage + ".zip";
File.WriteAllBytes(outputDir + "\\" + filename, exportXml);
exportLabel.Text = string.Format("Solution exported to {0}.", outputDir + "\\" + filename);
groupBox2.Enabled = true;
}
catch (FaultException<Microsoft.Xrm.Sdk.OrganizationServiceFault>)
{
throw;
}
}
