Is there a way to transfer a Visual Studio project to the MonoDevelop environment? at FAQ - MonoDevelop it is said that:

What version of MonoDevelop are you using? MonoDevelop 2.8 can open .NET 4.0 projects (I believe 2.6 can as well). In fact, in 2.8 .NET 4.0 is the default for all new projects.
Using a text editor, change your *.vbproj file to add the following line:
<TargetFrameworkVersion>v3.5</TargetFrameworkVersion>
to the first PropertyGroup, e.g.
<?xml version="1.0" encoding="utf-8"?>
<Project DefaultTargets="Build" ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<PropertyGroup>
...
<TargetFrameworkVersion>v3.5</TargetFrameworkVersion>
</PropertyGroup>
MonoDevelop's VB.NET addin still doesn't support .NET 4.0. It would work for C# projects.
I had the same problem in version 3.0 of MonoDevelop. VBNET development have changed the runtime. NET Tools> Options> Runtimes. NET I have marked as default MONO 2.x
.net framework 4.0 not yet completly implemented in mono but includes most of the features try to download latest version of mono and retry:)
