- [ ] Build-time break
|
|
|
|
### Recommended Action
|
|
|
|
This issue is fixed in a .NET Framework 4.5 servicing update. Update the
|
|
.NET Framework 4.5, or upgrade to .NET Framework 4.5.1 or later, to fix this
|
|
issue. Alternatively, this issue may be avoided by using the
|
|
<xref:System.Data.SqlClient.SqlConnection?displayProperty=name> in a 'using'
|
|
pattern (which is a best practice) or by explicitly calling Dispose or Close
|
|
when the connection is no longer needed.
|
|
|
|
### Affected APIs
|
|
* `M:System.Data.SqlClient.SqlConnection.#ctor(System.String)`
|
|
* `M:System.Data.SqlClient.SqlConnection.#ctor(System.String,System.Data.SqlClient.SqlCredential)`
