Problem (c-sharp):

(Pop up)

Invalid version format expected "[Major]"."[Major]""[minor]"

With GUID Greyed out

Possible solution 1: I have had this happened to me in the past. This can be more of a Visual Studio problem more than anything else.

What this means is that the AssemblyInfo.cs file is either missing from the Properties folder in the project or there is a permissions issue. If there is a permissions issue, update the ACL (File > Properties > Security), close and re-open the project. If missing altogether, you just need to recreate it taking the following steps:

• Within Visual Studio 2010, select Tools > Create GUID.
• Click Copy (or New GUID then Copy).
• Click Exit.
• Expand the Properties folder in the Solution Explorer (Control+W+S to open).
• Delete the AssemblyInfo.cs file shown with the exclaimation point.
• Double click on the Properties folder – this should open the Properties window.
• On the Application Tab, click the Application Information… button.
• Fill in the application information, paste the GUID you copied into the GUID field – when done click OK.

Possible solution 2:

<ItemGroup>
    <Compile Include="AssemblyInfo.cs" />
</ItemGroup>
Usually, this file is in the subfolder "Properties"

<ItemGroup>
    <Compile Include="Program.cs" />
    <Compile Include="Properties\AssemblyInfo.cs" />
</ItemGroup>
